Wadsworth Boulevard Widening Project, 35th Avenue to I-70

Brandmark for 2E Projects Wadsworth

Project Update  

The City of Wheat Ridge completed the Environmental Assessment (EA) for the Wadsworth Boulevard Widening project from 35th Avenue to I-70 and in September 2019, received the federal approvals to move into final design.

The current schedule for finalizing the project and moving into construction is below:

  • Right-of-way acquisition process: Summer 2019 - Spring 2020
  • Construction: 2020-2022

Proposed Design

During the early stages of the EA for the Wadsworth Widening project, the Colorado Department of Transportation (CDOT) voiced concern over the number of signalized intersections described in the original 2015 Planning and Environmental Linkages (PEL) Study, which was intended to be the design basis for the EA. 

This concern led the City to consider alternative design options for the corridor to better align the goals of the City with the needs of CDOT. Of the designs considered, a simple version of a Continuous Flow Intersection for both 38th and 44th Avenues seems to meet CDOT and the City’s objectives best by helping to reduce congestion while improving the corridor’s ability to serve drivers, bikes, pedestrians, and transit. CFIs are innovative intersection designs that are increasingly being used around the country. In Colorado they can be found in Durango, Loveland, and will soon be built in both Douglas and Arapahoe Counties. To see how a CFI would work at 38th and Wadsworth, please watch the video below.

Project History

On March 9, 2018 the City of Wheat Ridge hosted four "Block by Block" meetings for business and property owners in the Wadsworth Boulevard Widening project area. Over 70 property and business owners participated in the four meetings, where the City shared the latest project updates including access plans, possible property impacts, schedule updates, ideas about eventual construction phasing, and the most current roadway design. These discussions also gave the City a chance to gather additional feedback from property and business owners prior to finalizing the Environmental Assessment for the project.

Meeting materials from select prior public meetings are provided below.

Environmental Assessment

In April 2016, the City of Wheat Ridge initiated an Environmental Assessment (EA) for the widening of Wadsworth Boulevard. The study has reviewed environmental impacts associated with transportation improvements planned for Wadsworth between 35th Avenue and I-70.

The EA is part of Wheat Ridge’s project to prepare for the widening of Wadsworth Boulevard, with construction projected to begin in 2020. This work builds off of a Planning and Environmental Linkage (PEL) study for Wadsworth that was completed in 2015 with input from the local community. The major components of the proposed project are to reconstruct the street to a 6-lane section; provide better bicycle, pedestrian, and transit facilities; manage driveway access to the street; and provide enhanced amenity zones along the corridor, particularly in the City Center section between W. 38th and W. 44th Avenues.

A public open house to discuss the EA was held on May 22, 2019. Materials presented include:
