Road Construction Updates

Road Construction Updates
Posted on 10/15/2021

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 150 active work zones within the city.

Traffic engineering staff do make an 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.
Please be patient, slow down and respect the workers and equipment required to maintain well-functioning infrastructure in the city.

Fitzsimons-Peoria Stormwater Outfall Project
Work is being done to upgrade the stormwater conveyance capacity in the Fitzsimons-Peoria corridor to meet current city standards. When completed, the project will provide improved flood protection to about 230 residents and 40 businesses. Visit for details. 

Major Road Projects in East Aurora
Significant work is underway in several areas to improve mobility on the east side of Aurora. Visit this story map to learn more (updated July 16, 2021).

Quincy Avenue/Gun Club Road Intersection Improvements
The traffic switch to the new and permanent alignment of Quincy Avenue and Gun Club Road was completed earlier this summer.  Please use caution as the traffic switch has created new traffic patterns.

The PCFI design was selected because of its efficiency in reducing delays and travel times for busy intersections like Quincy Avenue and Gun Club Road. These intersections are primarily different in the turn lane layouts.  

The new left turn crossover lanes were constructed for both northbound and southbound Gun Club Road. Drivers will enter the left turn lane about 1,000 feet before reaching the intersection. Separating the left turn lane reduces wait times and allows more drivers to pass both straight and left through the intersection during each green light. Similarly, bypass right turn lanes were added in all directions, allowing drivers to merge with flowing traffic without stopping at a light. 

The project also includes new E-470 on/off ramps, where a new signal has been placed south of the intersection. All these improvements are intended carry much heavier traffic volumes through this entire area, which is close to E-470, Aurora Reservoir and Arapahoe County Fairgrounds.

RTD 15L (East Colfax) Route Improvements

RTD is upgrading 37 bus stops between Broadway in Denver and I-225 in Aurora to include enhanced shelters with lighting, security cameras and benches. Other improvements such as queue bypass lanes, bus bulbouts (curb extensions) and expanded boarding areas will be added in key locations along the corridor.

Bus shelter installations started June 7 and are continuing through the summer. Telecommunication and electrical installations inside the shelters will continue through the fall. Installation schedules are subject to change. During shelter installations, temporary bus stop closures will be in place. Adjacent stops in the same direction and at the same intersection will not be closed at the same time to accommodate RTD customers. Temporary sidewalk and roadway lane closures also are anticipated while the work is taking place. Please follow all construction and detour signage for your safety. To receive closure updates, sign up for RTD Rider Alerts

Changes coming to I-70: Improvements recommended at I-70/Airpark and I-70/Watkins interchanges
The area in Arapahoe and Adams counties surrounding the interchanges at I-70/Airpark and I-70/Watkins Road is planned for substantial new development. Arapahoe County is leading a study to proactively identify recommended improvements at each interchange to meet future travel demands. 

Following detailed forecasting of future traffic volumes and patterns, interchange design alternatives were developed and evaluated. The study is now nearly complete, and recommendations were presented at an Aug. 25 virtual public meeting (visit the project webpage to replay the meeting). Improvements at each interchange would likely be constructed in phases to provide adequate traffic operations as the area continues to grow. 

Improvements recommended by this initial study will next need to be evaluated in a formal environmental clearance process before final design and construction can begin. Timing of construction is uncertain since funding for these next steps has not yet been identified. Current projections of area development show initial phases of improvements could be necessary before 2025. Arapahoe County is actively working with local partners to create a funding plan.

State Highway 83 (Parker Road) Concrete Panel Replacement
The Colorado Department of Transportation and contractor Ralph L. Wadsworth are conducting work to improve several sections of roadway along Parker Road (State Highway 83) from E-470 to Arapahoe Road. This includes removal and replacement of damaged concrete panels, ADA curb ramp improvements, guardrail improvements, and joint sealing to minimize the effects of surface water infiltration.
