Road Safety Audit— Route 16 (Medford & Everett) & River’s Edge Drive (Medford)
Prepared by Fay, Spofford & Thorndike
Background
Fay, Spofford & Thorndike of Burlington, Massachusetts is the Massachusetts Department of
Transportation – Highway Division’s (MassDOT) prime design consultant for the Bridges M-12-017 and
E-12-004=M-12-018 (Woods Memorial Bridge) Reconstruction Project, Everett & Medford (604660).
The Project primarily consists of the reconstruction of Route 16 over the Malden River (Woods Memorial
Bridge, E-12-004=M-12-018), the reconstruction of Route 16 over the MBTA railroad tracks (Bridge M12-017) and the reconstruction of the bridge approaches on Route 16 (Revere Beach Parkway).
As part of the project design process, the crash history within the project limits was researched. The
research revealed that there were crash clusters within the Project limits that were in the top 5% of
clusters in the Metropolitan Area Planning Council (MAPC) boundaries. As a result of these clusters,
which were identified on MassDOT’s online database and established using crash data from 2006-2008, a
Roadway Safety Audit (RSA) was conducted. Additionally, MassDOT guidelines require a RSA to be
conducted where HSIP-eligible crash clusters are present, as they are in this instance.
A Roadway Safety Audit, as defined by the Federal Highway Administration, is a formal safety
performance examination of an existing or future road or intersection by an independent audit team. This
RSA was conducted during the Preliminary Design (25% Design) stage of the Project in order to
incorporate safety-related design features early in the design process. Elements of the RSA will be
considered for incorporation into the Project as the design progresses.
Project Data
The Roadway Safety Audit was conducted on July 21, 2011 at 10 AM, with the pre- and post-audit
meetings held at the Massachusetts State Police Barracks Station A-4, 520 Fellsway in Medford. As can
be seen in Table 1, the Audit Team consisted of a cross-section of State and Local engineering,
enforcement, maintenance and emergency response professionals and was assembled in conjunction with
input from MassDOT’ Safety Management Unit.

Audit participants were provided with materials to review prior to the Audit. The materials included a
summary of traffic volume data (daily and peak hour), vehicle classification (i.e. truck) data and vehicle
speed data. An existing conditions field survey plan was also provided. Participants were encouraged to
visit the site prior to the Audit and were urged to consider elements on MassDOT’s Safety Review
Prompt List (also included).
The day of the Audit, a pre-Audit meeting was held at the Massachusetts State Police Barracks to discuss
the Audit process, review the distributed materials and to discuss the some of the issues that Team
members had observed individually, prior to the Audit.
The Audit Field Walk consisted of field observations of the Audit locations. Handwritten notes and
digital photographs documented the observations made by Audit Team members during the Field Walk.
Following the Audit Field Walk, a post-Audit meeting was held at the State Police Barracks where the
Team confirmed the observations made in the field and offered solutions to remedy the safety deficiencies
noted in the Field Walk and Pre-Audit meeting.

Road Safety Audit— Route 16 (Medford & Everett) & River’s Edge Drive (Medford)
Prepared by Fay, Spofford & Thorndike
Project Location and Description
The Audit locations were as follows:
• The intersection of River’s Edge Drive and the Route 16 Westbound Ramps (Medford), and
• The segment of Route 16 (Revere Beach Parkway) between Santilli Circle (Everett) and the
Route 16 Ramps to River’s Edge Drive/Wellington MBTA Station (Medford).
Intersection of River’s Edge Drive and the Route 16 Westbound Ramps
River’s Edge Drive is an urban minor arterial that is under the jurisdiction of the City of Medford. The
roadway runs north-south between the Medford-Malden City Line to the north and the MBTA Wellington
Station to the south and, according to traffic counts conducted in 2011 as part of the Project, carries
approximately 17,600 vehicles per day (vpd). In Malden, the roadway is named Commercial Street and
provides connections to Malden Center. The roadway generally consists of one lane in each direction,
with auxiliary lanes provided at intersecting roadways or private properties. At the intersection, two
northbound approach lanes (one through lane and one shared through and right turn lane) are provided.
Two southbound approach lanes are provided at the intersection (one 500 foot long exclusive left turn
lane and one through lane). Bike lanes on the roadway are provided in each direction, north of the Route
16 westbound ramps. A sidewalk is provided on the east side of the roadway, north of the Route 16
westbound ramps and on the west side of the roadway, south of the Route 16 westbound ramps. The
MBTA rail/subway tracks are west of River’s Edge Drive and run parallel to the roadway. The speed
limit on River’s Edge Drive is 30 MPH, established by regulation by the City of Medford. However,
there are no posted speed limits on the roadway.
The Route 16 Westbound ramps are classified as an urban minor arterial that is under the jurisdiction of
the MBTA and carries traffic between River’s Edge Drive and Route 16. The ramps carry approximately
10,700 vpd, according to traffic counts conducted in 2011 as part of the Project. The westbound off-ramp
approach to the intersection consists of one exclusive right turn lane and one exclusive left turn lane.
There are no sidewalks or dedicated bicycle lanes on the ramps. The travel lanes on the ramps are of
sufficient width to accommodate bicycle travel.
This T- intersection is under traffic signal control and includes a protected-permissive southbound leading
left turn phase (from River’s Edge Drive to the ramps) and an exclusive pedestrian phase which allows all
pedestrian movements to occur simultaneously while all vehicular traffic is stopped. The pedestrian
signal includes audible tones for the visually impaired.
Route 16 Corridor
The Route 16 corridor that is being evaluated as part of the Audit is approximately 1,500 feet long and is
the segment of Route 16 (Revere Beach Parkway) between Santilli Circle (Everett) and the Route 16
Ramps to River’s Edge Drive/Wellington MBTA Station (Medford). The Everett/Medford City line is
located along the Malden River. The roadway is classified as a Principal Arterial, carries approximately
73,500 vpd (according to traffic counts conducted in 2011 as part of the Project) and is a major east-west
Page 3
Road Safety Audit— Route 16 (Medford & Everett) & River’s Edge Drive (Medford)
Prepared by Fay, Spofford & Thorndike
roadway that links Medford to Everett and Revere to the east and Arlington to the west. This segment of
Route 16 crosses over the MBTA railroad tracks (Bridge M-12-017) and over the Malden River (Woods
Memorial Bridge, E-12-004=M-12-018).
This segment of Route 16 (Revere Beach Parkway), is under the jurisdiction of the Massachusetts
Department of Conservation and Recreation (DCR). The two bridges, however, are under the
jurisdiction of MassDOT.
The posted speed limit on Route 16 within the Audit segment is 35 MPH. According to the DCR, speed
regulation documentation establishing the speed limit does not exist.
The Route 16 Audit corridor features three travel lanes in each of the eastbound and westbound
directions, with acceleration and deceleration lanes provided at the on/off ramps to River’s Edge
Drive/Wellington MBTA. Sidewalks are also present on both sides of the roadway in this segment. The
roadway is a median divided, with guardrail separating the two travel directions on Route 16.
The Route 16 ramp system, located within the limits of the Audit, provides access between Route 16
(eastbound and westbound) and River’s Edge Drive and the MBTA Wellington Station. On and off
ramps are present on each of the eastbound and westbound directions of Route 16.
The Bridges M-12-017 and E-12-004=M-12-018 (Woods Memorial Bridge) Reconstruction Project,
Everett & Medford (604660).
As part of the Commonwealth’s ongoing Accelerated Bridge Program (ABP), Route 16 over the Malden
River (Woods Memorial Bridge, E-12-004=M-12-018) and Route 16 over the MBTA railroad tracks (M12-017) will be entirely reconstructed (superstructure and substructure replacement). The project also
includes the reconstruction of the approaches to each of the bridges and the Route 16 ramp system. As a
result, the segment of Route 16, between Santilli Circle in Everett and Brainard Avenue in Medford will
be reconstructed as part of the project. The Project is currently at the 25% Design stage.
Crash History
As part of the project design process, the crash history within the project limits was researched. The
research revealed that there were crash clusters within the Project limits that were in the top 5% of
clusters in the Metropolitan Area Planning Council (MAPC) boundaries. The clusters were identified on
MassDOT’s online database and established using crash data from 2006-2008. The cluster map is
contained in Appendix C.
Additionally, Sgt. Richard Huber of the Massachusetts State Police participated in the Audit and noted
that a large proportion of the crashes within the Audit corridor occur at the Route 16 ramps. Sgt. Huber
noted that the crashes at the ramps are typically of the rear-end type, where the driver on the on-ramp
attempting to enter into mainline Route 16 traffic will begin accelerating and then will stop unexpectedly.
As a result, the vehicle behind the stopped vehicle will collide with the stopped vehicle. Sgt. Huber did
not recall any crash related fatalities within the Audit corridor, in recent memory.

Audit Observations
Audit Team members were solicited for their observations during the Pre-Audit and Post-Audit meetings
and during the Audit Field Walk. The Audit Team members offered the following observations on
roadway and intersection issues as they relate to safety.
Intersection of River’s Edge Drive and the Route 16 Westbound Ramps
Pavement Markings and Signs
• The “Left Lane Must Turn Left” sign on the southbound River’s Edge Drive approach (at the
STOP line) is blocked by vegetation and not visible to an approaching motorist;
• The “Right Lane Must Turn Right” sign on the westbound Route 16 Westbound ramps approach
(at the STOP line) is blocked by vegetation and not visible to an approaching motorist;
• “No Turn on Red” sign facing northbound River’s Edge Drive traffic is mounted on the far right
side of the approach but is not mounted adjacent to a signal face and may not be seen by drivers
who are accustomed to the sign being adjacent to a signal head;
• Signal Ahead (graphical sign) mounted on the off-ramp approach to the intersection is obscured
by vegetation and is not visible to an approaching motorist;
• Wayfinding is difficult at the
intersection for drivers who are
unfamiliar with the roadway
network – an insufficient
number of guide signs was
noted;
Looking North - Sidewalks are not present on the east side of River’s Edge Drive
• Pavement markings are worn
in certain areas and edge line
pavement markings are not
present on the Route 16
westbound ramps, which may
provide less guidance to
drivers during nighttime and
adverse weather conditions;
• There are no signs facing Route 16 westbound on-ramp traffic to warn of a sharp change in the
horizontal alignment at the horizontal curve on the westbound ramp. During periods of limited
visibility, it is possible that drivers may not realize there is a curve and drive straight, instead of
traveling along the curve.
Page 6
Road Safety Audit— Route 16 (Medford & Everett) & River’s Edge Drive (Medford)
Prepared by Fay, Spofford & Thorndike
Multi-Modal Accommodation
• Sidewalks are not present on the east side of River’s Edge Drive, south of the Route 16
Westbound ramps. A sidewalk is present only on the northbound side of River’s Edge Drive,
north of the Route 16 westbound ramps. Currently, pedestrians who are walking south on River’s
Edge Drive (north of the ramps) must cross at the intersection to the sidewalk on the west side of
the roadway in order to continue walking south on River’s Edge Drive towards the Wellington
MBTA Station or to Route 16 eastbound;
• Bicycle lanes are not present in the northbound and southbound direction of River’s Edge Drive,
south of the Route 16 westbound ramps. Bicycle lanes are present north of the Route 16 ramps,
in both directions of River’s Edge Drive. Bicycles must currently use the vehicular travel lanes
south of the Route 16 ramps to/from the Wellington MBTA Station and Route 16 Eastbound;
• Bicycle lanes are not present in the eastbound and westbound directions on the ramps between
Route 16 Westbound and River’s Edge Drive. Bicycles currently have to ride in the travel lane
with vehicular traffic.
Obstructions
• The existing Route 16 eastern bridge abutment and retaining wall limits the intersection sight
distance for westbound right-turning ramp traffic (looking south) during right turns made on the
red signal. Vehicles have been observed making right turns on the red signal from the off-ramp
while northbound vehicles coming from the area of the MBTA station (who are shown a green
signal) were in close proximity;
• Visibility of traffic signal heads
looking north on River’s Edge
Drive (south of Route 16) is
limited by a horizontal curve on
River’s Edge Drive and the
presence of the bridge and
bridge abutments. The signal
indications cannot be seen until
the tangent section of River’s
Edge Drive under the bridge,
which is approximately 250 feet
of visibility;
Looking south from the ramps – sight distance is
limited due to the wall and abutment

Prepared by Fay, Spofford & Thorndike
Speed
• The clearance intervals for the existing traffic signal is 3 seconds of yellow and 1 second all red.
These intervals are insufficient for a design speed of 35 MPH and the width of the intersection.
The clearance intervals calculated according to the Manual of Traffic Signal Design, Second
Edition (Institute of Transportation Engineers; Washington, DC; 1998) should be 4 seconds of
yellow and 3 seconds of all red.
Route 16 Corridor
Pavement Markings and Signs
• Pavement markings at the Route 16 eastbound ramp deceleration lane do not guide through
traffic to stay in through lanes as vehicles travel over the MBTA bridge crest vertical curve. As a
result, some through vehicles were observed to be in the ramp’s deceleration lane before having
to make a sudden
maneuver to the left to
remain in the through
lane;
• The Route 16 Eastbound
guide sign for the
Wellington MBTA station
is partially covered by
vegetation and is not
entirely visible to drivers;
Guide signs to Route 99 and to Mystic View
Road are confusing and partially obstructed
Page 8
Road Safety Audit— Route 16 (Medford & Everett) & River’s Edge Drive (Medford)
Prepared by Fay, Spofford & Thorndike
• Guide signs and pavement markings directing vehicles to Route 99 and Mystic View Road on
Route 16 eastbound (near Santilli Circle) are poor. The signs are small, confusing and partially
covered by vegetation. Currently drivers must make the first right turn before Santilli Circle to
access Mystic View Road and the second right turn to access Route 99. The existing guide signs
appear to be insufficient in distinguishing between the correct turn to make to access Route 99
versus the turn to access Mystic View Road;
• The guide signs for Route 99 and Mystic View Road are currently too closely spaced together;
• There is a general lack of guide signs in the corridor;
• Traffic control (signs and markings) are missing/not present for vehicles entering Route 16
westbound from the on-ramp. Drivers are not informed of whether there is a merge, yield, STOP
or added lane condition as the vehicle enters on to Route 16 westbound. The pavement markings
also do not provide any visual cues to the driver;
• Traffic control signs are missing/not present for vehicles entering Route 16 westbound from
Santilli Circle (from Route 99 and Mystic View Road). Drivers are not informed of whether
there is a merge, yield, STOP or added lane condition as the vehicle enters on to Route 16
westbound;
• There are no signs indicating
that there is a sharp change
in horizontal alignment on
the Route 16 westbound onramp. During periods of
poor visibility, there is no
guidance for drivers that
there is a sharp change in the
horizontal alignment of the
ramp;
Traffic signs and appropriate pavement markings are missing at the Route 16 Westbound ramps
• The STOP sign facing Route 16 eastbound on-ramp traffic is visible to Route 16 eastbound
through traffic and may cause vehicles to stop on Route 16. The sign is barely visible to on-ramp
traffic;
Page 9
Road Safety Audit— Route 16 (Medford & Everett) & River’s Edge Drive (Medford)
Prepared by Fay, Spofford & Thorndike
• There is no STOP line to supplement the STOP sign on the Route 16 eastbound on-ramp
approach to Route 16 eastbound. Drivers are not being provided with guidance for the location at
which to stop their vehicle before entering onto Route 16 eastbound;
• There are no signs present that indicate turns that can be made to reverse direction on Route 16.
Multi-Modal Accommodation
• Crosswalks and wheelchair ramps are not present at the Route 16 eastbound and westbound
ramps. Pedestrians must cross the roadway without the visibility and regulatory protection that a
crosswalk typically provides;
• Sight distance for pedestrians crossing the off-ramp is restricted for a westbound pedestrian on
the Route 16 westbound sidewalk, due to the location of the sidewalk on the triangular island at
the ramp, overgrown vegetation and the horizontal alignment of the roadway. As a result, a
crossing pedestrian is not visible to vehicles on Route 16 who may be using the exit ramp and be
in potential conflict with a
crossing pedestrian;
Sight distance for pedestrians crossing the westbound offramp is restricted
• Bicycle
lanes/accommodation are
not present on Route 16.
Currently, bicyclists were
observed travelling in the
vehicular travel lanes on
Route 16 and on the
sidewalks. Some
bicyclists were observed
travelling in the opposite
direction of the flow of
vehicular traffic;
• Tactile warning panels that assist visually impaired pedestrians are not present on the existing
wheelchair ramps across the Route 16 west leg of Santilli Circle;
Page 10
Road Safety Audit— Route 16 (Medford & Everett) & River’s Edge Drive (Medford)
Prepared by Fay, Spofford & Thorndike
Obstructions
• Existing trees on the triangular island at the Route 16 eastbound ramps limit the visibility of
vehicles on the entrance ramp to Route 16 to oncoming traffic, making it difficult to enter the
mainline Route 16 traffic stream.
Speed
• Stopping sight distance on Route 16 over both crest curves on the Woods Memorial Bridge and
the MBTA bridge appears to be substandard and may limit driver visibility over the bridges for
the speed at which vehicles are travelling. The Woods Memorial Bridge vertical curve was
designed for 40 MPH and the MBTA bridge vertical curve for 40 MPH. The 85th percentile
speed on Route 16 is approximately 44 MPH;
• Stopping sight distance to the traffic signal heads that control the pedestrian crossing on the slip
lane to Mystic View Road appears to be insufficient for the travel speed. Sight distance is
limited by the combination of a horizontal curve and overgrown roadside vegetation, making it
difficult to see the traffic signal heads until the vehicle is relatively close to the crossing, which
may be an insufficient distance to stop in time for a crossing pedestrian, depending on the speed
of the vehicle.
Auxiliary Lanes
• Acceleration lanes/deceleration lanes on Route 16 at the ramps between Route 16 and Wellington
MBTA Station/River’s Edge Drive are substandard for the travel speed. Vehicles exiting Route
16 are not provided with sufficient area to decelerate before exiting, thus vehicle deceleration
occurs in the right through lane, which may be unexpected by a driver of a through vehicle and
may be a contributing factor to accidents. Vehicles entering Route 16 are not provided with an
acceleration lane of sufficient length to enter onto Route 16 mainline traffic and thus vehicles
may have difficulty entering the traffic stream and which may also lead to vehicles stopping
unexpectedly before merging into mainline traffic, which could also be a contributing factor to
accidents;
• The roadway grade of the eastbound on-ramp to Route 16 appears to be steep, which makes it
difficult for vehicles to maintain an appropriate speed while accelerating onto mainline Route 16;
• The acceleration lane for vehicles coming around Santilli Circle from Route 99 is substandard for
the travel speed. Vehicles entering Route 16 are not provided with an acceleration lane of
sufficient length to enter onto Route 16 mainline traffic and thus vehicles may have difficulty
entering the traffic stream.
Lighting
• According to prior observations, the existing roadway did not appear to be well lit and may be a
contributor to accidents that occur during the nighttime hours;
Page 11
Road Safety Audit— Route 16 (Medford & Everett) & River’s Edge Drive (Medford)
Prepared by Fay, Spofford & Thorndike
Other
• The existing W-Beam shape of the guard rail on the Route 16 median (dividing the two travel
directions) may be substandard in preventing departures of an errant vehicle into the opposing
travel lanes;
• Trucks are restricted on Route 16 westbound to the right lane only. It is not known if the existing
bridge can now structurally accommodate truck traffic in the left and center lanes, due to ongoing
bridge maintenance efforts
• The chain link fence on the Route 16 median island that currently prevents pedestrians from
illegally crossing Route 16 at mid-block is difficult to see at night. Pedestrians had been
observed (outside of the Audit Field Walk period) crossing at mid-block, using holes in the fence.
A scenario that may possibly occur is that a pedestrian would begin a mid-block crossing of
Route 16 at night without realizing that a fence is present, until the pedestrian is in close
proximity to the fence ;
• The paved area adjacent to the Route 16 westbound off ramp (near the sharp change in horizontal
alignment on the ramp) is large enough such that multiple vehicles were observed to be parking
adjacent to the ramp, which is undesirable, as there is limited sight distance for parked vehicles
exiting this area.
Outside the Audit areas:
• The geometry and layout of the Wellington MBTA Station/parking access roads should be
improved. It currently could be very confusing for users who are unfamiliar with the station’s
roadway layout;
• As an eastbound Route 16 driver crosses Route 28 at Wellington Circle, the three eastbound
through receiving lanes (east of Route 28) do not align properly with the three through approach
lanes (west of Route 28). The eastbound rightmost approach lane aligns with an acceleration lane
that ends. The lanes appear to be offset by the width of one full lane.

Potential Safety Enhancements
The Audit Team members offered potential safety enhancements that could be implemented to mitigate
the safety related observations that were noted in the previous section of this report. Audit Team
members were encouraged to develop short, medium and long term safety enhancements.
Intersection of River’s Edge Drive and the Route 16 Westbound Ramps
Pavement Markings and Signs
• Trim vegetation around signs to provide visibility to approaching motorists;
• Install guide signs at the intersection to improve wayfinding. New signs to improve wayfinding
may include a sign directing vehicles to Route 16 Eastbound (facing southbound River’s Edge
Drive traffic), south of the Route 16 westbound ramps. The guide signs directing drivers to
Malden Center and the MBTA station, facing the ramp approach to the intersection, are also
missing and should be replaced. Guide signs on Route 16 should also include River’s Edge Drive
as a destination, in addition to the Wellington MBTA station;
• Reapply the existing markings at the intersection to replace the worn out pavement markings;
• Apply pavement marking edge lines on the Route 16 Westbound ramps;
• Install horizontal alignment warning signs facing Route 16 westbound on-ramp traffic to warn of
a sharp change in the horizontal alignment of the ramp in order to better guide drivers during
periods of limited visibility;
• Construct an extension to the existing triangular island that divides on and off-ramp traffic to
improve channelization of traffic along the sudden change in horizontal alignment of the ramp.
Multi-Modal Accommodation
• Construct a sidewalk along the east side of River’s Edge Drive, south of the Route 16 Westbound
Ramps. This sidewalk should meet the existing sidewalk south of the bridge. Providing a
sidewalk while maintaining two northbound vehicular travel lanes on River’s Edge Drive would
necessitate the relocation of the east bridge abutment;
• Provide bicycle lanes on River’s Edge Drive south of the Route 16 Westbound Ramps, which
would eliminate the gap in the provision of bicycle lanes between the MBTA station and River’s
Edge Drive. Providing bicycle lanes while maintaining the existing number of travel lanes on
River’s Edge Drive would necessitate the relocation of the bridge abutments;
• Provide bicycle lanes on the Route 16 westbound ramps in order to provide accommodation for
bicyclists on the ramp. The existing ramps appear to be of sufficient width to accommodate a
bicycle lane;
Page 13
Road Safety Audit— Route 16 (Medford & Everett) & River’s Edge Drive (Medford)
Prepared by Fay, Spofford & Thorndike
• Replace existing pedestrian signal heads with pedestrian signal heads that include countdown
pedestrian timer display.
Obstructions
• Evaluate the impact on intersection capacity of posting a NO TURN ON RED sign facing the
Route 16 westbound off-ramp approach so that vehicles would be prohibited from making this
movement, due to the limited intersection sight distance looking to the south. If the impacts of
restricting turns on red on this approach are acceptable, a NO TURN ON RED sign should be
mounted;
• Relocate the east MBTA bridge abutment to improve the intersection sight distance (looking
south) for vehicles making the right turn on red signal from the Route 16 westbound off-ramp
approach and to improve visibility of the intersection and signal for northbound River’s Edge
Drive vehicles;
• Improve the visibility of the traffic signal by mounting signal backplates on all signal heads at the
intersection. The backplates provide a dark contrasting background for the signal head that is
expected to make the head more visible. The ability of the existing mast arms and foundations to
accommodate the additional loading generated by the backplates should be evaluated prior to any
potential installation;
• Improve the visibility of the traffic signal for northbound vehicles on River’s Edge Drive by
adding a signal head facing northbound traffic on the existing mast arm that is closest to the
bridge. The ability of the existing mast arm and foundation to accommodate the additional
loading generated by the addition of the signal head should be evaluated. The need for this
improvement should also be more closely evaluated.
Speed
• Conduct a formal study to determine the appropriate traffic signal clearance intervals for River’s
Edge Drive northbound and southbound traffic and implement the revised clearance intervals at
the intersection.
Route 16 Corridor
Pavement Markings and Signs
• Install painted dotted lane marking extension lines along the deceleration and acceleration lanes
at the Route 16 ramps. The dotted extension lines will provide delineation between the
acceleration/deceleration lanes and the through lanes and is expected to provide enhanced
guidance to drivers entering and exiting Route 16. The 2009 MUTCD requires the use of dotted
extension markings (Section 3B.04) at acceleration and deceleration lanes;
• Trim vegetation around signs to provide visibility to approaching motorists;
Page 14
Road Safety Audit— Route 16 (Medford & Everett) & River’s Edge Drive (Medford)
Prepared by Fay, Spofford & Thorndike
• On the Route 16 eastbound approach to Santilli Circle, remove existing guide signs for Route 99
and Mystic View Road and install improved guide signs that provide better guidance for drivers
for the right turn towards Mystic View Road and the right turn to access Route 99;
• Remove and reset existing diagrammatic guide sign (Route 99/Mystic View Road/Route 16 East)
to a location that provides greater separation between existing guide signs;
• Install a cantilevered overhead sign over the exclusive right-turn lane on the Route 16 eastbound
approach at Santilli Circle. The sign legend should direct drivers to turn right to access Route 99;
• Add guide signs along Route 16 in both directions that direct drivers to River’s Edge Drive and
Malden Center prior to the off-ramps;
• Install the appropriate signs facing drivers on the Route 16 westbound on-ramp approach to Route
16 westbound, based on existing roadway conditions, to provide drivers the required traffic
control as they accelerate onto Route 16 westbound;
• Install a yield sign facing drivers coming from Santilli Circle (from Route 99 and Mystic View
Road) onto Route 16 westbound;
• Rotate the STOP sign facing Route 16 eastbound on-ramp traffic such that it is not visible to
drivers on Route 16 and visible to on-ramp traffic;
• Install a STOP line on the on-ramp approach to Route 16 eastbound;
• Install signs at the Route 16 off-ramps in both directions (“TO REVERSE DIRECTION USE
NEXT EXIT”) and near Santilli Circle (“TO REVERSE DIRECTION USE NEXT RIGHT”) that
indicate the turns to make to reverse direction on Route 16.
Multi-Modal Accommodation
• Install painted crosswalks and construct wheelchair ramps at the Route 16 ramps. The location of
the crossing should ensure that a crossing pedestrian is visible from the Route 16 ramp
deceleration area;
• Evaluate and potentially construct a multi-use path of a width such that pedestrians and high
speed bicyclists (such as commuters) and low speed bicyclists (such as recreational bicyclists)
can be comfortably accommodated along Route 16, in both directions. Under this scenario, a
dedicated bicycle lane would not be provided on Route 16 as all bicyclists would be
accommodated on the path;
• Evaluate and potentially construct a multi-use path of a width such that pedestrians and bicyclists
(low speed only) can be comfortably accommodated along Route 16, in both directions. Under
this scenario, the roadway would also be widened to provide a minimum 5 foot bicycle lane on
Route 16 (in each direction of travel) to accommodate higher speed bicyclists (such as
Page 15
Road Safety Audit— Route 16 (Medford & Everett) & River’s Edge Drive (Medford)
Prepared by Fay, Spofford & Thorndike
commuters). The widening of Route 16 and the bridges is expected to have considerable impacts
and is a substantial project;
• If bicycle lanes on Route 16 are provided, ensure that the design of bicycle lanes on Route 16
account for the safe crossing of the Route 16 ramps for a bicycle travelling through on Route 16;
• If bicycle lanes on Route 16 are provided, ensure that the design of bicycle lanes on Route 16
account for the safe transition of bicycles back to segments of roadway that do not have bicycle
lanes (i.e. Wellington Circle, Santilli Circle);
• Install tactile warning panels for visually impaired pedestrians on each of the wheelchair ramps
along the Route 16 west leg of Santilli Circle. The panels are now required on new wheelchair
ramp installations. The installation of the panels on each existing wheelchair ramp will
necessitate the entire reconstruction of each wheelchair ramp.
Obstructions
• Trim or remove the trees on the triangular island at the Route 16 eastbound ramps to increase
sight distance.
Speed
• Construct the replacement for the Woods Memorial Bridge and the MBTA Bridge, both of which
are to be reconstructed as part of the Project. The current design of the replacement for the
Woods Memorial Bridge features a vertical curve that can accommodate 50 MPH speeds. The
current design of the replacement for the MBTA bridge features a vertical curve that can
accommodate 40 MPH speeds;
• Trim the vegetation along the slip lane to Mystic View Road (near Santilli Circle) to improve
visibility of the traffic signal on the slip lane (that controls the pedestrian crossing), giving drivers
sufficient opportunity to see the traffic signal and stop when a pedestrian is in the crossing;
• Relocate the painted crosswalk closer to Route 16 eastbound, so that the crossing is visible to
mainline traffic. Relocation of the crosswalk would also necessitate the construction of new
wheelchair ramps, and necessitate the relocation of the sidewalk on the traffic island to link the
relocated crosswalk to the crossing of Route 16.
Auxiliary Lanes
• Widen Route 16 roadway and bridges at the ramps and at Santilli Circle to provide standard
length acceleration lanes that can accommodate the travel speeds on Route 16. The widening of
Route 16 and the bridges is expected to have considerable impacts and is a substantial project;
• Regrade the ramps and Route 16 to reduce the steep uphill grade for drivers attempting to merge
on to Route 16 eastbound;
Page 16
Road Safety Audit— Route 16 (Medford & Everett) & River’s Edge Drive (Medford)
Prepared by Fay, Spofford & Thorndike
• Ensure that any potential improvements to auxiliary lanes do not significantly impact traffic
safety and operations at the intersection of Route 16 westbound and Brainard Avenue. Ensure
that Route 16 westbound on-ramp traffic merges onto mainline Route 16 westbound before
Brainard Avenue.
Lighting
•
Identify overhead street lights that are out of service and replace with new bulbs or fixtures;
•
Replace the roadway lighting along the corridor with a new lighting system and hardware.
Other
• Evaluate the existing guardrail in the median for its suitability in preventing vehicle departures
into oncoming traffic and replace the median guardrail with guardrail or barrier that is suitable for
preventing vehicle departures into oncoming traffic. F-Shaped concrete barrier or Thrie-beam
steel guardrail may be suitable for use in the median on Route 16;
• Review the bridge inspection reports to determine if the truck restrictions (on the left and center
lanes) on Route 16 westbound can be eliminated, allowing for truck traffic to use all lanes;
• Install a new fence on the median island that is visible to pedestrians at night, so that pedestrians
can see that mid-block pedestrian crossings of Route 16 are not possible. Methods to make the
fence material and/or posts more visible will be investigated and may include retroreflective
painting of the fence post and/or visible fencing materials;
• Install temporary concrete barrier along the Route 16 westbound off ramp to prevent vehicles
from parking on the ramp. Supplement the barrier with pavement marking edge lines;
• Installing curbing to improve the delineation of the ramp travel lane and eliminate the excess
paved area.
Other Areas
• Reconstruct the MBTA Wellington Station access roads to parking, live parking, bus stops;
• Conduct a formal study to improve the lane markings Wellington Circle such that the lane offset
for Route 16 eastbound vehicles is eliminated. Implement the findings of the study;

Summary of Road Safety Audit
For each safety enhancement noted in the previous section, the following (Tables 2 and 3) is a summary
of the proposed enhancement, its potential safety payoff, the estimated time frame for completion, the
estimated construction cost, and the responsible agency.
Safety payoff estimates are based on engineering judgment and are categorized as follows: low, medium,
and high (>71%). The time frame is categorized as short-term (<1 year), mid-term (1 to 3 years), or longterm (>3 years). The costs are categorized as low (<$10,000), medium ($10,000 to $50,000), or high
(>$50,000).
For enhancements that are expected to be incorporated into the design of the Bridges M-12-017 and E-12004=M-12-018 (Woods Memorial Bridge) Reconstruction Project, Everett & Medford (604660), the
responsible agency will be listed as “Project”. The Project will be constructed as part of the
Commonwealth’s Accelerated Bridge Program and the awarding authority for the Project is MassDOT.
The Project is currently under design, with the preliminary highway design (25% Design) to be submitted
in September of 2011. As of the writing of this report, the project construction is expected to begin in
2013 and be complete by 2016.
