Current Activity

Update May 13, 2022:

Crews continue building the detour on the north side of W. 72nd Avenue from Oak Street to Swadley Street. Most work will take place on the shoulder north of W. 72nd Avenue, but the work may require single lane closures. Flaggers will be on-site if a lane is closed. Expect delays in the area.

Please be aware:

Pierson Court at W. 72nd Avenue is permanently closed. Access to W. 72nd Avenue from Pierson Court and access to Pierson Court from W. 72nd Avenue is prohibited. All residents and local traffic still have access to their properties from W. 71st Place. This closure supports the City’s project goal of minimizing impacts to local residents throughout the corridor while providing an improved roadway system for all users.

  • The westbound W. 72nd Avenue shoulder continues to be closed from Oak Street to Swadley Street and Quail Street to Simms Street for the next several weeks.
    • Flaggers will be on-site starting Monday, May 9 on westbound W. 72nd Avenue, between Swadley Street and Oak Street directing one-way traffic while crews pave the roadway.
    • Temporary and permanent fence installation and utility work continue this week in various sections of the project corridor.
    • Third-party utility operations will be in place on the south side of W. 72nd Avenue from Quail to Oak streets.
    • Asphalt pavement removals start Monday, May 23 on eastbound W. 72nd Avenue between Swadley and Oak streets.

The speed limit on W. 72nd Avenue is reduced to 25 mph all along the corridor. Please drive safely and responsibly through the work zone.

Project Delivery

The City will be using an alternate contracting method, called Construction Manager/General Contractor (CM/GC), to deliver this project. The CM/GC will be an integral part of the project team for the remainder of design and it is expected they will also perform construction services once the first design package is approved for construction. It is anticipated that project construction will be phased.

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.

On February 13, 2019 bonds were issued to provide funding for the 72nd Ave. and Ralston Road projects.

Over the next several months, the City's CM/GC contractor and utility companies will begin performing field work for utility relocation, and installation of new utilities. Coordination efforts will continue with land owners and other stakeholders, including the Union Pacific Railroad, Xcel Energy, etc.

What Makes the W. 72nd Ave. Project Important?

W. 72nd Ave. is an arterial parkway and a major east-west corridor for Arvada’s transportation network, serving 21,000 vehicle trips each day. It provides connectivity to major north-south corridors including three State Highways (SH-95/Sheridan Blvd., SH-121/Wadsworth Blvd., and SH-72/Indiana St). This regional corridor not only serves all of Arvada, it provides access to Westminster and Golden/Jefferson County. Major destinations served by W. 72nd Ave. include the Arvada Center for the Arts and Humanities, the Apex Center, West Woods Golf Club, Majestic View Nature Center, and regional shopping. Several school are also accessed via this corridor, including Oberon and North Arvada Middle Schools; Lincoln Academy; and Campbell, Van Arsdale, and West Woods Elementary Schools.

The Citizens’ Capital Improvement Plan Committee (CCIPC) twice ranked improvements to W. 72nd Ave. as a high priority. The project also meets concerns expressed in recent Arvada Citizen Surveys. And 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 and roadways will perform at the lowest levels of service.

Why W. 72nd Ave. Needs to Be Improved

  • 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.
  • Add sidewalks for pedestrians.
  • Upgrade signalized intersections with the latest traffic signal equipment and technology.
  • Resolve significant drainage issues along W. 72nd Ave. 

This project required the taking of several properties in the vicinity of the railroad underpass. The City team has met with all affected property owners and will continue to be open and transparent about the process. As the project moves forward, affected property owners will be provided a fair market value for their property that is acquired.
