About the Project

This major improvement project includes modernizing and improving Wadsworth from 35th Avenue to I-70 with efficient and safe intersection designs at 38th and 44th Avenues, safer entrances and exits for vehicles accessing businesses, and a continuous sidewalk on the west and a bike/pedestrian path on the east side of Wadsworth from 35th Avenue to the Clear Creek Trail. The project will transform Wadsworth into a multimodal roadway that enhances traffic operations, improves access, and supports the vision of a livable, walkable mixed-use corridor.

The City of Wheat Ridge led the planning and design effort for the project and will oversee the construction phase. Please visit for the latest information on the project.

Following concerns about the number of intersections with traffic signals that were proposed in the 2015 Planning and Environmental Linkages (PEL) Study, the city presented alternative design options. One of those alternatives—a Continuous Flow Intersection (CFI) for both 38th and 44th Avenues—was chosen as it will help reduce congestion while serving drivers, cyclists, pedestrians, and transit. CFIs are innovative intersection designs that are increasingly being used around the country. In Colorado they can be found in Durango, and Loveland, and will soon be built in both Douglas and Arapahoe counties.
