Public Hearing for the I-70 East Supplemental Draft Environmental Impact Statement (SDEIS)
Sept. 23, 5 to 8 p.m.
Sable Elementary School, 2601 Sable Blvd.
The Colorado Department of Transportation (CDOT) on Aug. 29 released a study of the future of the I-70 East
corridor from Brighton Boulevard to Tower Road, including the 50-year-old viaduct in north Denver. This study, known
as a Supplemental Draft Environmental Impact Statement, looks at three different alternatives and their impacts to
environmental and social resources. In addition, a preferred alternative is preliminarily identified that would remove
the viaduct between Brighton and Colorado boulevards, lower the highway below grade, add two tolled express lanes
in each direction, and build an almost four-acre landscaped cover over the interstate. The public is encouraged to
review and comment on the study, including attending this public hearing. An open house is scheduled from 5 to 6
p.m. to speak with project team members and examine exhibits providing detail about the project. The presentation
and formal comment period will happen from 6 to 8 p.m. Comments also may be submitted by mail to I-70 East EIS
Team, Colorado Department of Transportation, 2000 S. Holly St., Denver, CO 80222; email at contactus@i70east.com; telephone at 303-757-9413; and online at www.i-70east.com. Copies of the study are available at www.i70east.com and at libraries, city halls and government offices. The comment period ends Oct. 14.
Interstate 70: Tower Road to East Colfax Avenue update
The Colorado Department of Transportation (CDOT) is reconstructing the 2.5-mile segment of Interstate 70 between
Tower Road and Colfax Avenue (U.S. 40/287). Work for The this project consists of removing the existing asphalt
and replacing it with concrete pavement, shoulder widening, and new bridges over the Union Pacific Railroad and
Smith Road. The project also includes new drainage ponds, guardrails, curbs and gutters, signing and striping.
The left hand lane of I-70 eastbound from Tower Road to Colfax Avenue will be closed until mid-2014. This will take
that stretch of eastbound I-70 down to one lane for the duration of the closure. This work is necessary to demolish
and reconstruct the westbound bridge. During this time, the westbound traffic will be crossed over to the eastbound
lanes.
One lane of westbound traffic will be closed for the duration of this phase of the project. Originally, the design for this
project included two year lane reductions along this stretch taking each direction of I-70 down to one lane through
summer 2015.
The bridge demolition and reconstruction that is part of this project will replace a bridge that is at capacity. The bridge
currently in place will be replaced with a bridge that can handle the volume and speed of traffic traveling that stretch
of road. The new bridge will also include wider shoulder lanes that will improve safety for all motorists as well as allow
for future expansion to three lanes each direction.
During this phase of construction, the on ramp from northbound Tower Road to eastbound I-70 and the on ramp from
northbound E-470 to I-70 will not have dedicated acceleration lanes. Please use caution in these areas and be aware
of surrounding traffic. Motorists traveling in this area are encouraged to allow for extra time to get to their destinations
and to use caution. By removing and replacing the bridge in two segments traffic flow can continue on this stretch of
road with lane reductions.
Speed limits in the area have been reduced from 75 miles per hour to 55 miles per hour. This is an active
construction area on a busy stretch of roadway; please go Slow InThe Cone Zone.
City Road Construction Work
Peoria Grade Separation Construction Update
The Peoria Frontage road between Smith and 33rd opened to traffic Aug. 29. Access will be from the 33rd Avenue
teardrop and Smith Road. Smith Road closed to traffic Sept. 2 for reconstruction and should reopen Sept. 8 unless
delayed by weather or unforeseen circumstances.
Drivers need to be alert to the new Peoria alignment and the “One Way” status of Quentin between 33rd and Smith
Road. Peoria no longer has an at-grade crossing of the Railroad Tracks and access to the areas south of Smith Road
is by using 33rd Avenue.
Work on 39th Avenue east of Peoria continues and the new Peoria Frontage Road between 37th and 39th is now
open providing easier access to the businesses on the east side of the new overpass.
Unless delayed by weather the project is expected to be substantially complete by the end of September.
Bridge over Coal Creek closed
The bridge over Coal Creek on Jewell Avenue east of Gun Club Road and Murphy Creek is closed for some time for
repairs. Additional information will be posted when it is available.
Water main work rescheduled
According to Aurora Water, the water line replacement project at South Buckley Road and East Wagon Trail Parkway
has been postponed for several weeks. We will alert motorists when the work has been rescheduled.
Weekly construction updates for city of Aurora projects are posted on the city’s website weather permitting. For more
information, call the Street Division at 303-326-8200.
Aurora Water projects also are available on the website.
New Updates as of Sept. 11, 2014: The Aurora Line/I-225 Rail
Peoria Light Rail Bridge
Upcoming Construction Activities: Construction is in full force along the Aurora Line/I-225 Rail project. Crews will
begin construction of the light rail bridge that will cross over Peoria Street/Sand Creek at Fitzsimons Parkway as soon
as the week of Sept. 2, 2014. Construction activities will include building bridge piers, decking, abutments, walls and
guideway east and west of Peoria Street, and installing girders spanning over Peoria Street. Click here for more
information about the bridge construction process.
Peoria Street Traffic Impacts: For various construction activities, intermittent lane restrictions and nighttime full
closures will be required. Watch for weekly website updates and construction alerts detailing these
restrictions/closures as they approach. To avoid traffic congestion in this area, use I-70 or I-225 as alternate routes.
Keep in mind that:

Possible nighttime work may occur

Activities may cause noise and vibration

Bus routes may be temporarily relocated
Corridorwide Traffic Impacts: Construction will require periodic lane restrictions and detours throughout the 10.5mile project. For your safety, and the safety of our workers, motorists should use extreme caution when driving
through construction zones. Pay attention to message boards and increased truck traffic.
Work Performed by Others: Additional work performed by Aurora Water, Xcel Energy and other construction
companies will also occur throughout the project and be communicated separately by each responsible entity.
Business Impacts: Business access will be maintained at all times, however alternate access may be required to
facilitate construction. Please continue to support local businesses.
