56th Avenue at Peña Boulevard: 
Operational & Safety Improvements


Translate This Page


Denver's Department of Transportation and Infrastructure (DOTI) is planning improvements to 56th Avenue across the Peña Transportation Corridor, from Old Buckley Road east to approximately 400 feet east of the Regional Transportation District (RTD) A-Line rail bridge. The purpose of the project is to improve traffic operations, improve safety at the interchange and enhance multimodal use and connectivity.

The Project includes the Peña Boulevard interchange and transition to 56th Avenue:

  • extending four travel lanes west under Peña which will taper back into the existing two-lane section near Old Buckley Road
  • ramp improvements to Peña Boulevard
  • a median
  • a stormwater detention pond;
  • a multi-use trail connection on the north side of 56th Avenue through the existing Peña interchange, connecting to Old Buckley Road.

The sidewalk along the south side of 56th Ave between the Peña interchange and Memphis Street will be constructed in a separate City-funded project.
