Road Construction Work in Progress

Weather delays may be expected for all work zones.

Please note: Although the city informs online mapping services about our road closures and designated detours/alternate routes, the routes they provide to the general traveling public are generally the shortest or quickest routes between two points. That results in drivers sometimes not following the city's designated detour/alternate routes.

Check the road construction updates webpage and the city's social media channels for any unexpected changes to schedules.

Project update

Great progress continues on the Parker-Quincy-Smoky Hill Intersection Improvements Project. Asphalt paving throughout the project area is now complete, marking a major milestone as the project moves into its final stages.

Crews are currently working on remaining items, including traffic signal work, installation of final signage, and landscaping throughout the project area. Traffic signal work will continue over the coming weeks, with all traffic signals anticipated to be fully operational by the second week of November.

Motorists will continue to see crews working throughout the intersection while these final improvements are completed. Please use caution when traveling through the work zone and watch for workers, equipment and temporary traffic control.

We appreciate the community's continued patience and cooperation as we near completion!

REGIONAL PARTNER CONSTRUCTION UPDATES

East Colfax BRT

Project information:

East Colfax BRT Construction continues in Aurora from Yosemite to I-225:

Construction will be completed in a single phase, with work occurring simultaneously at both eastbound and westbound stations.
Traffic control cones and lane closures will be used in active construction zones as work progresses.
Traffic will remain open in the center lanes of East Colfax Ave. throughout the project.
Work will progress block by block, with each section expected to take about 3 to 6 months to complete.
Construction work for the side-running stations will occur within designated work zones that include portions of the sidewalk.

The BRT project continues the work started in Denver to replace the existing 15 and 15L buses and save bus riders up to 30 minutes in travel time from Union Station to the R Line Station at I-225.

More information—including a small business toolkit with resources for how to thrive during construction—is available at DenverGov.org/ColfaxBRT. Business owners also may take a self-assessment to consider how your business might be impacted by construction and what you may need to do to prepare. Additional resources are available from the Aurora South Metro Small Business Development Center (SBDC).
