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. 

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.
