As the city of Aurora improves its infrastructure offerings to its current and future residents, demands for more infrastructure, improvements and repairs also grow. On any given work day, there can be as many as 100 active work zones within the city.
Traffic engineering staff make every effort to minimize the impact of these work zones to the traveling public. In addition to reviewing and approving the plans to ensure they are safe and compliant with all regulations, staff also work with contractors to seek alternatives to street closures and minimize the number of lane closures and their duration. Staff also try to keep conflicting work zones from overlapping in time or space. In most cases, these efforts are successful. However, on occasion, alternatives are not available and since we are dealing with the outdoor environment, even the best planned projects get delayed by weather, special events or unknown conditions, resulting in confusion and/or unplanned congestion.

Interactive map available
The city has an online map that shows work happening throughout the city that may impact travel on roadways. The map captures annual street maintenance work, transportation projects, public and private utility work, and development projects impacting roadways. Visit this link to view the map.
Annual Street Maintenance Work

Other Road Construction Work (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.

56th and Hudson Road Closures and Project
(view map for aerial view of closure impacts and alternate routes)
Please note: Flood damage has restricted access to both 56th Avenue and Hudson Road. Heavy rainfall undermined the roadways and destroyed the road surface in some locations. The road closures are necessary to protect the traveling public while the project team works to reopen the roadways. Project information will continue to be posted on the project webpage as it becomes available.
-56th Avenue between Monaghan and Hudson
Both directions of 56th Avenue between Monaghan and Hudson roads are fully closed around the clock due to extensive road damage. The replacement road is currently being designed, and construction is now estimated to start in late fall 2026. Follow the signed detour; use alternate routes. The detour route uses Monaghan Road or Imboden Road between 26th Avenue and 56th Avenue.
-Hudson Road between 56th Avenue and 26th Avenue
Both directions of Hudson Road between 56th and 26th avenues are fully closed around the clock due to extensive road damage. The replacement road is currently being designed, and construction is now estimated to start in late fall 2026. Follow the signed detour; use alternate routes.

I-70 Picadilly Interchange
Frequent traffic pattern changes are expected in the coming weeks as crews work toward opening the entire interchange to traffic. Drivers are encouraged to use extra caution traveling through the work zone, especially with potential winter weather conditions.
Colfax detour in place for eastbound I-70 access
Eastbound traffic on East Colfax Avenue that normally can merge directly onto eastbound Interstate 70 continues to be rerouted via a short detour until late 2025 as part of this project.
Traffic is being diverted south to follow the new Picadilly Road, 13th Avenue, the old Picadilly Road and then back onto the I-70 Frontage Road. Drivers should turn north at E-470 to re-enter eastbound I-70. Expect delays and use alternate routes if possible.
A short stretch of the I-70 Frontage Road between the new Picadilly Road and old Picadilly Road also is closed. Westbound traffic on that frontage road will follow the same detour in reverse to connect with westbound Colfax.
** Due to the holidays, traffic impacts for the next two weeks will be listed below.
Eastbound I-70
-There will be no closures from Thursday, Jan. 1, through Sunday, Jan. 4.
-Please be cautious: Trucks may be entering I-70 from the shoulders.
Westbound I-70
-There will be no closures from Thursday, Jan. 1, through Sunday, Jan. 4.
-Please be cautious: Trucks may be entering I-70 from the shoulders.
Picadilly Road south of Smith Road
Picadilly Road, between Smith Road and East 19th Avenue, will remain closed as crews complete utility relocations, roadway removals and reconstruction. Currently, crews are moving into building the roadway.
-Traffic is detoured to Sicily Street. Parking on Sicily Street is not allowed during this closure.
Construction activities are site- and weather-dependent and subject to change.
Diverging Diamond Interchange Opening
Due to unforeseen circumstances, the diverging diamond interchange full opening to travelers is now projected for early January, weather-permitting.
Once the interchange is open, Picadilly Road, from East 19th Avenue to Smith Road, will remain closed until early 2026. Finishing work associated with temperature and weather-dependent activities will continue through spring 2026.

Work to rehab four I-225 bridges now complete
The Colorado Department of Transportation completed work in late November to improve the driving surface of the northbound and southbound Interstate 225 bridges over Second and Sixth avenues. Thank you for your patience as crews helped improve the safety for motorists through the area!
Over the course of 69 working days, crews logged 6,134 hours to complete a significant scope of work:
- Eight bridge expansion joints were replaced.
- 2,206 linear feet of roadway grinding and overlay was complete.
- More than 100 cubic yards of concrete was poured and finished.

I-70 drainage improvements near Airport Boulevard
The Colorado Department of Transportation and its contractor, Myers and Sons Construction, are improving drainage along a one-mile span of Interstate 70 near Exit 285 toward Airport Boulevard to help manage stormwater and make the highway safer. The anticipated project completion is late December.
This project will enhance driver safety by preventing hydroplaning, ice formation and improving driver visibility and in addition, extend roadway lifespan and durability by protecting the pavement from water.
Upcoming work hours:
-Daytime work hours are 7 a.m. to 5 p.m., Monday and Tuesday.
-In observance of the Christmas holiday, crews will not be working Wednesday, Dec. 24 through Friday, Dec. 26.
Upcoming traffic impacts:
-The off-ramp at Exit 285 to Airport Boulevard will have a right shoulder closure 24/7.

East Colfax Bus Rapid Transit
Aurora, in partnership with the city and county of Denver, RTD, CDOT and DRCOG, is celebrating the ongoing construction of the East Colfax Bus Rapid Transit (BRT). Construction is not expected to reach Aurora until early 2026.
Watch the Colfax BRT series, Col-FAQS: On the Street.
BRT systems are designed to move more people with more safety, efficiency and reliability. Buses will run down dedicated center transit lanes in Denver and in mixed flow through Aurora, significantly reducing travel times within the project’s boundaries—from Union Station in Denver to RTD’s R-Line Station at I-225 in Aurora.
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) at AuroraGov.org/SBDC.
