W 57th Ave Corridor Study

The City is studying the W 57th Avenue corridor from Garrison Street to Upham Street and a small section of Grandview Avenue from Independence Street to Garrison Street.

The study is looking at ways to improve mobility and safety along the corridor for people bicycling, walking, and driving. The 2017 Bicycle Master Plan identified this corridor as the most important bike route in the city and this corridor study is the next step in developing improvements in this area.


The project has installed temporary curb extensions, speed cushions and traffic circles at the following locations:

Curb extensions

  • W. 57th Avenue and Glen Ellen Drive
  • W. 57th Avenue and Cody Street
  • W. 57th Avenue and Carr Street
  • W. 57th Avenue  and Brentwood Street
  • W. 57th Avenue and Arvada K8 Entrance

Speed cushions

  • 57th & Everett
  • 57th & Dover
  • 57th & Carr

​​Traffic circles

  • 57th & Balsam
  • 57th & Ammons
  • 57th & Yarrow
  • 57th & Yukon


To help guide drivers through the intersections, signs and pavement markings will be installed. The No Parking Zone at these intersections will increase from 30' to 50' to provide better visibility and enhance safety for pedestrians, bicyclists, and motorists. 

Speed studies will evaluate the efficacy of these roadway treatments. More information will be posted once those studies have been completed.
