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.

New interactive map now available
The city has launched a new 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
The 2024 road construction projects map is now posted. See the Weekly Roadwork Construction Schedule

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.

East Colfax Bus Rapid Transit
Aurora, in partnership with the city and county of Denver, RTD, CDOT and DRCOG, is preparing for the rollout of the East Colfax Bus Rapid Transit (BRT). The city of Aurora negotiated an intergovernmental agreement with Denver to fund the design and construction of BRT elements along the Aurora portion of Colfax.
Construction on the BRT has begun in Denver and will move east, likely reaching Aurora in late 2025. City officials joined federal, state and other local officials Oct. 4 for a groundbreaking ceremony for this project.
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.
Businesses along the Colfax corridor can take a self-assessment to ready themselves for construction. More information—including a small business toolkit with resources for how to thrive during construction—is available at DenverGov.org/ColfaxBRT. Additional resources are available from the Aurora South Metro Small Business Development Center (SBDC) at AuroraGov.org/SBDC.
