SR 302 - E of Elgin Clifton Rd to SR 16 - Remove Fish Barriers, Paving and ADA Compliance

Project news

  • WSDOT encourages travelers, residents and local businesses to sign up for email notifications regarding this project.
  • This project removes and replaces three fish barrier culverts under SR 302 with fish passable structures and repaves nearly 7 miles of highway along with ADA improvements for bicyclists and pedestrians.
  • The greatest traffic impact will be up to three weekend closures of the SR 302 Purdy Spit for bridge deck repairs. The bridge deck work will take place day and night. A signed detour will be in place during construction.
  • Crews will also be addressing the on- and off-ramps from SR 16 to SR 302. 

Needs & benefits

This cumulative project will remove and replace three fish barrier culverts on State Route 302 in Pierce County with fish passable structures (two with larger culverts and one with a bridge). Additionally, crews will repave nearly 7 miles of highway, complete deck repairs to the Purdy Spit and make ADA improvements for bicyclists and pedestrians at the intersections of SR 302/Purdy Drive NW and SR 302/94th Ave NW.

During construction, drivers should expect daytime lane and shoulder closures, extended weekend closures, extended on- and off-ramp closures and up to a full, weeklong closure of the Purdy Spit for deck repairs. Contractor crews for WSDOT will conduct earthwork, culvert installation, paving, guardrail repairs and installation, stream profile realignment, stream restoration, erosion control and water management.  

The End Result

This work is part of WSDOT’s Fish Passage Barrier Removal Program, which identifies and removes barriers to fish caused by culverts under state highways. WSDOT works in partnership with the Washington State Department of Fish and Wildlife to identify fish species under state-owned highways and project anticipated habitat gain. Once complete, the potential habitat gain for fish is 25 miles (21.3 miles for Minter Creek and 3.7 miles for Little Minter Creek).
