W. 72nd Avenue Bond Project

The speed limit on W. 72nd Avenue is 25 mph. Please obey speed limits through the construction zone. Alternate routes are advised.

Week of May 28

For your safety and that of workers, please keep out of the construction zone. Avoid wet concrete and stay on designated access paths.

Simms to Oak St.

  • Tuesday, May 30 to Tuesday, June 13 a full closure of the Oak Street and W. 72nd Avenue intersection will be in place. ​
    • Please reference the detour map and follow posted detour signage.
    • Use Simms and Kipling streets, and W. 80th and W. 66th avenues for alternate access.
    • Once the closure is in place, crews will work through the night. Noise and vibrations from back up alarms and construction equipment, and excess light from light plants is expected.
    • This closure is required for crews to remove roadway materials, and install the new drainage and water line system.
  • Pedestrian access is available on the south side from Simms to Oak streets. Please use signalized intersections to cross W. 72nd Ave. 
    • See the pedestrian access map
    • During the closure at Oak Street pedestrian access will be closed across the W 72nd Avenue and Oak Street intersection and on Oak Street from 72nd to Owens Street.


  • Utility companies will continue work east of Oak to Kipling streets for the foreseeable future, with an estimated completion date of July 2023—weather and supply chain-dependent.
    • Crews will be potholing for utilities between Swadley Court and Oak Street throughout the week.

The Public Works department presents to the City Council with updates about the bond projects at W. 72nd Avenue and Ralston Road. 

Project Background

  • In the November 6, 2018 election, Arvada residents approved Ballot Issue 3F for a bond issue to fund improvements to Ralston Road and W. 72nd Ave.
  • W. 72nd Ave. is a major east-west corridor for Arvada, serving 21,000 vehicle trips each day. This regional corridor provides access to Westminster and Golden/Jefferson County. 
  • The Citizens’ Capital Improvement Plan Committee (CCIPC) ranked improvements to W. 72nd Ave. as a high priority.
  • The project also meets concerns expressed in recent Arvada Citizen Surveys. 
  • The 2014 Comprehensive Plan generated transportation models indicating that the congestion, operation and safety of W. 72nd Ave. will deteriorate with the build-out of the City.

Why Improvement is Needed

  • West of Kipling St., W. 72nd Ave. shrinks abruptly from four lanes to two, creating a bottleneck.  
  • The at-grade Union Pacific Railroad crossing near Oak St. creates major traffic backups when a train passes through.  
  • The intermittent or absent sidewalks create unsafe conditions for pedestrians and cyclists. 

What the Project Entails

  • Widen W. 72nd Ave. between Kipling and Simms Streets to match the road east of Kipling, eliminating the bottleneck.  
  • Create an underpass at the Union Pacific Railroad crossing near Oak St. to eliminate traffic backups.
  • Add bike lanes and sidewalks.
  • Upgrade signalized intersections.
  • Resolve significant drainage issues along W. 72nd Ave.
