CDOT to begin intersections improvement project in Aurora

August 22, 2019 - Denver Metro Area, Colorado - Intersections include Colfax Ave. at Chambers Rd., Colfax Ave. at I-225, and Tower Rd. at I-70

AURORA On Sunday, August 25, the Colorado Department of Transportation will begin an intersections improvement project at three locations in Aurora, starting with the E. Colfax Avenue (US 40/US 287) and Chambers Road intersection. To minimize traffic impacts, crews will conduct nighttime operations Sundays through Thursdays, from 8 p.m. to 5:30 a.m.

The project will improve safety for motorists and pedestrians and support traffic growth in the area. Crews will replace traffic signals, curb ramps and sidewalks in compliance with the Americans with Disabilities Act (ADA), add and widen left-turn lanes at the E. Colfax Ave. intersections, and widen the Interstate 225 northbound ramps.


During working hours, motorists can expect reduced speed limits through the work zone and various lane closures. The tentative schedule is as follows; however, these activities are weather dependent and are subject to change.

Location 1: Intersection of E. Colfax Ave. (US 40/US 287) and Chambers Road

Dates: Late August – October 2019

Work: Replacing traffic signal and sidewalks in compliance with the ADA, and adding a second left-turn lane on westbound E. Colfax Ave. onto Chambers Rd.

Impacts: Speed limit reduced to 30 mph, west and eastbound single lane closures, and sidewalk closures


Location 2: Intersection of E. Colfax Ave. (US 40/US 287) and Interstate 225

Dates: September – November 2019

Work: Replacing traffic signal and sidewalks in compliance with the ADA, widening of I-225 northbound ramps, extending and adding left-turn lanes at E. Colfax Ave. intersection.

Impacts: Speed limit reduced to 30 mph, west and eastbound lane closures, sidewalk closures, and possible ramp closures

Location 3: Intersection of Tower Road and Interstate 70

Dates: November 2019

Work: Replacing traffic signal and sidewalks in compliance with the ADA

Impacts: North and southbound single lane closures, sidewalk closures, possible I-70 ramp closures

Crews will complete the left-turn lane improvements by late November. At that time, the project will be suspended until spring 2020, when work will resume with the installation of new traffic signals at the three locations.



  • Timeline: August 2019 to June 2020

  • Watch for workers. Drive with caution.
  • Don't change lanes unnecessarily.
  • Avoid using mobile devices such as phones while driving in work zones.

To heighten safety awareness, CDOT recently announced its Whole System — Whole Safety initiative. This project takes a systematic statewide approach to safety combining the benefits of CDOT’s programs that address driving behaviors, our built environment and the organization's operations. The goal is to improve the safety of Colorado’s transportation network by reducing the rate and severity of crashes and improving the safety of all transportation modes. The program has one simple mission—to get everyone home safely.



CDOT has approximately 3,000 employees located throughout Colorado, and manages more than 23,000 lane miles of highway and 3,429 bridges. CDOT also manages grant partnerships with a range of other agencies, including metropolitan planning organizations, local governments and airports. It also administers Bustang, the state-owned and operated interregional express service. Governor Polis has charged CDOT to further build on the state’s intermodal mobility options.
