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 February 6

Recent winter weather has caused rough road conditions in some areas. The project team is aware of various potholes through the corridor. The team is working to repair potholes as soon as possible. Thank you for your patience and please use caution driving through the work zone. 

Simms to Oak St.

  • Monday, Feb. 6-Tuesday, Feb. 7: asphalt roadway removal continues between Simms and Oak Streets
  • Pedestrian access has switched to the south side from Simms to Oak Streets. Please use signalized intersections to cross W. 72nd Ave. 
  • Flaggers will continue directing one-way traffic intermittently on W. 72nd Avenue from Swadley Court to Oak 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.

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. 

2022 Updates

Take a look at just a few of the numbers that reflect some of the work completed this year on W 72nd Ave. 108,000 square feet of pavement and 14,400 square feet of sidewalk removed. 11,000 square feet of retaining wall and 1,900 linear feet of cedar fencing installed. Progress is being made and we look forward to the completed upgrades through the corridor.
