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

Project news

  • Bridge construction at Minter Creek is nearly complete. Most work is on winter suspension. Crews have minor task items such as guardrail installation and others that may require intermittent lane closures.
  • Beginning this summer, crews will remove the outdated culvert at Minter Creek and the two culverts at Little Minter Creek. View Pierce County travel alerts for most current, real-time events near SR 302/SR 16.
  • The SR 302 Purdy Spit Bridge deck repairs will be addressed in a future project that is currently under environmental review. 
  • Travelers and local residents are encouraged to sign up for email notifications

Needs & benefits

This large 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 8 miles of highway and make ADA improvements for bicyclists and pedestrians at the intersections of SR 302/Purdy Drive NW and SR 302/94th Ave NW.

The speed limit from mileposts 10 to 11 is reduced from 45 mph to 25 mph. Travelers should expect weekday daytime lane and shoulder closures through summer of 2021.

During construction, drivers should expect daytime lane and shoulder closures at the culvert sites, and weekday, overnight on- and off-ramp closures from SR 16 to SR 302. Contractor crews 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).
