56th Avenue Widening: Peoria Street to Peña Boulevard Operational & Safety Improvements

Denver's Department of Transportation and Infrastructure (DOTI) is continuing design for a project that will widen 56th Avenue from Peoria Street to Peña Boulevard. Construction is expected to begin late Summer/early Fall 2021. 

56th Avenue serves as a major east-west regional thoroughfare. As a connection to Denver International Airport (DEN) and the Montbello and Parkfield neighborhoods, 56th Avenue is in need of improved mobility and capacity. 

The project, which is funded by the Elevate Denver Bond Program, consists of widening 56th Avenue between Peoria Street and Peña Boulevard from two to four lanes and constructing a multi-use path along the north side of 56th Avenue for connections to the neighborhood bike lanes and the trail system at the Rocky Mountain Arsenal National Wildlife Refuge.

  • Develop more convenient, safer access to the Montbello neighborhood from 56th Avenue
