Project news

• Beginning the week of June 29, Granite Construction crews will make pavement repairs during overnight hours along State Route 302 and the adjacent SR 16 ramps in Purdy. Weeknights from 8 p.m. to 6 a.m. the following day, crews will reduce SR 302 to a single alternating lane of traffic controlled by flaggers between milepost 10.7 near Key Peninsula Highway to milepost 16.9 at SR 16. All work is weather dependent and could be rescheduled. Ramp closure details: TacomaTraffic.com
• Travelers and local residents are encouraged to sign up for email notifications 
• View construction progress photos
• The greatest traffic impact will be up to three weekend closures of the SR 302 Purdy Spit for bridge deck repairs scheduled for summer 2020. The bridge deck work will take place day and night. A signed detour will be in place during construction.

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, complete deck repairs to the Purdy Spit Bridge 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 on SR 302 from mileposts 10 to 11 is reduced from 45 mph to 25 mph. Travelers should continue to expect weekday daytime lane and shoulder closures as work progresses throughout the summer.

During construction, drivers should expect daytime lane and shoulder closures at the culvert sites, three full weekend closures scheduled for summer 2020 for deck repairs, and weekday, overnight on- and off-ramp closures from SR 16 to SR 302.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).
