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.

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.

Project information will continue to be posted on the project webpage as it becomes available.

I-70 pavement repairs from Chambers to E-470
The Colorado Department of Transportation and contract partner, Villalobos Concrete, Inc., are repairing and replacing concrete pavement in both directions of Interstate 70 from Chambers Road to the E-470 exchange. The purpose of this state and federally funded project is to improve safety and mobility along a heavily traveled 6.6-mile stretch of the I-70 corridor.
Work includes replacing and grinding concrete pavement panels to provide a safe, smooth driving surface, and repairing and repaving the decks of four bridge structures within the project limits. The project has an anticipated duration of 16 months.
Work will take place Monday to Sunday, with working hours split between daytime and overnight shifts. Schedule adjustments will be made during the winter months.
- Sunday, Nov. 15, to Thursday, Nov. 19 - Eastbound I-70 from Chambers Road (exit 283) to Picadilly Road (exit 288)
A single right-lane closure will be in place overnight Sunday, Nov. 15, on eastbound I-70 from the Chambers Road exit to the Picadilly Road exit.
A single left-lane closure will be in place within the Chambers Road to Picadilly Road limits Monday, Nov. 16, and a single right-lane closure will exist nightly from Monday, Nov. 16, through Thursday, Nov. 19, between the Chambers and Picadilly exits.
Lane closure hours are 10 p.m. to 6 a.m.
Changing conditions and delays can be expected and caution is advised.

Northbound I-225 Bottleneck Mitigation Project
CDOT is starting construction in early October on a project to improve traffic flow on northbound I-225 between I-25 and Yosemite Street. The project will add an additional through-lane of travel on northbound I-225 to address congestion from merging traffic off I-25. The final configuration after construction will include four continuous lanes. Additional upgrades will include resurfacing and restriping northbound I-225 and improving the drainage infrastructure in the area.
The construction work will continue into December. Crews will alternate between nighttime and daytime construction throughout the project. General nighttime hours will be from 9:30 p.m. to 5:30 a.m. Sunday night through Thursday night and daytime hours are expected from 7 a.m. to 5 p.m. Monday through Friday.
During daytime hours, motorists can expect shoulder closures on northbound I-225 in the project area, with intermittent nighttime closures of the northbound I-25 and southbound off-ramps to northbound I-225. Detours will be in place during those closures. Additional single- and double-lane closures on northbound I-225 may occur during nighttime hours only.
The project team does not anticipate significant delays due to construction; however, motorists are encouraged to account for an extra 10 minutes of travel time. Slow down, watch for workers and equipment, and leave plenty of room between vehicles. Visit CoTrip.org for real-time lane closure updates and the project webpage for more details on the project.
ARTA I-70 Aerotropolis Parkway Interchange Project
The Aerotropolis Regional Transportation Authority and contract partner, Ames Construction, is constructing the I-70 Aerotropolis Parkway Interchange in Adams County.
Part of ARTA’s planned regional transportation infrastructure improvements across the district, the purpose of the project is to provide much-needed access to developments from Aurora and Adams County, and to improve connectivity to Denver International Airport and the adjacent area served by the Aerotropolis Regional Transportation Authority.
Visit the ARTA website for schedule and working hours and ongoing traffic impacts. For questions, call the project hotline at 720.388.2660 or email [email protected].
