Introductions
Purpose of the meeting
Overview of Public-Private Partnership (P3)
opportunity
Overview of toll lane study
Discuss opportunity for project in Long Range
Transportation Plan
Q & A and Discussion
Goals for South Shore Coalition Briefing
Provide overview of the P3 concept, origins
and benefits
• Introduce the Route 3 Express Toll Lane study
• Describe study process, next steps and
interest in Long Range Transportation Plan
• Answer questions
•
3
Why Express Toll Lanes on Rte. 3?
Address identified safety
problems
• Restore the breakdown
lane to its intended use
• Improve mobility for
autos and buses
• Reduce congestion
•

Public-Private Partnerships (P3): Overview
Legislature authorized P3 in 2009 Transportation
Reform
• A private concessionaire leases asset for 30-50
years, implements the project and returns the
facility in a state of good repair
• The financing mix can vary:
•
•
•
•
•
•
5
state payments;
private equity;
private loans; and
federal TIFIA loans
Toll revenues cover financing & maintenance costs
P3 Advantages
Opportunity to share or transfer risk
• Ability to pursue projects in times of limited
federal and state funding
• As in Design-Build projects, increased
opportunities for private-sector innovation and
improved project delivery
•
What is Project Mobility?
•
Project Mobility is a study to explore Express Toll
Lanes on Route 3 South
•
Proposed project runs from the Norwell-Marshfield
line, north of Exit 12, to Exit 18/19 at the Braintree
Split and beyond Exit 6 on I-93/Route128 in Quincy,
about 17 miles
•
Toll lanes would be in median with restored shoulder
•
Two toll-lane options are being studied:
•
•
•
7
two-lane reversible facility (reverses a.m. & p.m.)
single, permanent dedicated lane in each direction
Toll lane free for buses
Project Mobility Objectives
8
Key Issue is Safety:
Peak Period Breakdown Lane Use
More crashes and higher crash rate on Rte. 3
segments with active breakdown lane
• Data suggest peak-period breakdown lane use
influences crash rates
 Rte. 3 SB: 17% more crashes
•

Rte. 3 NB: 37% more crashes
• Project would restore shoulder for emergency use only
9
Key Issue is Safety:
High-Crash Locations Throughout Corridor
Rte. 3 interchanges are on State list of the highest
crash locations in Greater Boston region*
• Burgin Pkwy/Washington Street, Exit 18/19
• Union Street, Exit 17
• Main Street, Rte. 18, Exit 16
• Derby Street, Exit 15
• Hingham Street, Rte. 228, Exit 14
• Washington Street, Rte. 53, Exit 13
* MassDOT Highway Safety Improvement Program-identified crash clusters, 2011–2013 for the area between Merrimack Valley & Northern
Middlesex; Central Mass., and Old Colony.

Transportation & Mobility
Express toll lanes give drivers flexibility to
choose toll lane or existing lanes
• Research finds that few drivers choose to
use toll lanes all the time
• Detailed traffic and revenue
studies will determine appropriate tolls
• Travel time savings must be
significant to attract users and
reduce congestion in free lanes
•
17
Operational Issues
Goal is to use pricing to manage toll lane volumes
to maintain a minimum continuous speed of about
45 mph
• Goal is to improve travel speeds in general
purpose lanes by attracting drivers to the toll lanes
• All Electronic Tolling (AET) will prevent delays
associated with toll plazas
• Toll pricing structure has not been
established
•
18
Environmental Issues
•
•
•
•
•
•
19
Corridor has sensitive resources: wetlands,
water supplies, protected habitat
Majority of widening is within existing right-ofway and median
Unavoidable impacts to wetlands
Improvements to wildlife passages
Stormwater management benefits
Potential for noise barriers

Consistency with MPO Goals
Safety
Improves high-crash cluster locations identified
by MassDOT
• Adds capacity to help reduce peak-period
congestion and resulting rear-end collisions
• Restores breakdown lane for its intended
emergency-only use which may help reduce
crashes
•
23
•
Manages congestion using active lane
management and congestion pricing
•
Improves mobility for bus passengers with freeflow express lanes
•
Improves mobility for pedestrians and cyclists
with new accommodations on bridges
•
Reduces congestion on arterials
by improving travel time on Rte. 3

Consistency with MPO Goals
Capacity Management/Mobility
Consistency with MPO Goals
System Preservation
Helps achieve state of good repair
• Rehabs or replaces 27 bridges
• New pavement on existing lanes
• New ITS elements
•
•
25
•
Permanent Variable Message Signs
•
Fiber optic cable

Consistency with MPO Goals
Economic Vitality
Modernizes and expands Route
3 to improve access to existing
employment centers and homes
• Reduces auto and bus riders’
travel time
• Helps address perception of
South Shore as hampered by
mobility issues
•
