CDOT's contractor Design Construction Company will begin construction of modifications to the W. 55th Ave and Wadsworth Bypass intersection beginning as early as February 6. Expect lane reductions between 55th and 56th Avenues on Wadsworth Bypass and lane closures on 55th Avenue. Construction is anticipated to last approximately eight weeks weather permitting.

Overview

Construction of a new traffic signal at W 56th Ave and Wadsworth Bypass was completed in Fall 2016 to improve access to buses from the Olde Town Transit Hub.

The existing traffic signal at W. 55th Avenue and Wadsworth Bypass is as follows:

  • Eastbound and westbound right turn movements will continue to be allowed.
  • Northbound and southbound left turn movements are allowed and will be protected with turn arrows at the W. 55th Avenue and Wadsworth Bypass intersection.
  • U-turns at the adjacent traffic signals at W. 56th and W. 53rd Avenue will be allowed and protected with turn arrows.

Project Purpose

The purpose of the traffic signal at W 56th Ave is to serve commuters accessing the G Line Station (Olde Town Arvada) and improve progression on State Highway 121 (Wadsworth Blvd). An added benefit is that “cut through” traffic on W 55th Ave within the residential neighborhood will be reduced and traffic volumes will shift to W 56th Ave, which is a collector street.

Potential Impacts

The City of Arvada studied how this project impacts neighborhood circulation and travel. Alternative travel routes were evaluated and the results show that changes to the Wadsworth Bypass intersections will increase travel times between 1 minute and 2.5 minutes as shown in the attached Travel Time Heat Map.
