SR 16 and SR 302 (SPUR) Purdy Creek - Remove Fish Barriers and Paving

Project overview

This project improves habitat and passage for fish in Purdy Creek under SR 302 and SR 16.
Purdy Creek attempts to flow under SR 16 inside 40-year-old culverts. Unfortunately, the fish cannot navigate the old culverts. This project will remove and replace the old culverts with large bridge structures. The new bridge structures are 206-foot long. The Washington Department of Fish and Wildlife (WDFW) estimates this work will create approximately 5.6 miles of new habitat for juvenile Chinook, Coho, Chum, and adult and juvenile Steelhead, coastal cutthroat and sculpin.

Purdy Creek also runs under SR 302, through an old culvert before it enters the tidal flats of the Burley Lagoon. The culvert is challenging for fish to navigate. WSDOT will remove and replace the old culvert with a 77-foot-long bridge structure. WDFW estimates a total of 6.5 miles of habitat will be created for the same species of fish listed above.

This work will help preserve the integrity of the highways and reduce maintenance costs by reducing or eliminating the possibility of culvert blockages.

What to expect

During construction, travelers on SR 302 (SPUR) will use a detour route that will be in place for up to 10 months. The detour route will use Purdy Lane Northwest from 144th Street Northwest to SR 302/Purdy Drive Northwest. Drivers on both directions of SR 16 near Purdy Creek will see shifted lanes and a reduced speed limit in the construction zone and work areas.

This map shows the locations of where old culverts will be removed and replaced with a larger structure that will improve habitat for fish in Purdy Creek.
