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.

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.

Americans with Disability Act (ADA) improvement project begins on Colorado Highway 83 in early April
The Colorado Department of Transportation and prime contractor Chatos Concrete LLC, began an ADA sidewalk and curb ramp improvement project on April 6 along Colorado Highway 83 (Parker Road). Work is taking place at over 25 intersection locations between East Florida and East Quincy Avenue, Mile Points 68.8 to 74. The project is expected to be completed by July 2026.
Work will consist of removing and replacing concrete sidewalks and curb ramps at intersections throughout the project corridor, focusing on over 100 ramps that require upgrades to meet Americans with Disabilities Act (ADA) standards. Additional operations will include minor signage improvements, striping work, and push button enhancements.
Visit the project webpage for more information.
