US 101 - May Creek in Vic of Dowans Creek Rd - Remove Fish Barrier

Project news

  • This design-bid build fish passage correction project replaces an outdated culvert along US 101 near Forks at May Creek. The existing 9-foot diameter metal pipe will be replaced with a 175-foot-long concrete girder bridge for improved fish migration.
  • Olympic Peninsula travelers are encouraged to sign up for email alerts.

Needs & benefits

US 101 at May Creek near Forks has been identified as a barrier to fish migration. This project will eliminate barriers for resident salmon and other fish species while increasing potential upstream habitat. The work in the channel will simulate what is found in a natural stream bed.

May Creek is a tributary to the Bogachiel River, which is a popular breeding zone for fish. Once complete, this project is expected to produce nearly 8 miles of potential habitat gain for salmon and other species.

May Creek potentially supports Coho, Winter Steelhead, Coastal Cutthroat, and Resident Trout.

During construction, travelers will encounter one-way alternating conditions with a temporary signal. Crews will build a temporary bypass at the construction site to keep travelers moving. Any highway closures will be announced in advance.

Why is WSDOT correcting fish passage barriers under US 101 near Port Angeles?

Correcting fish passage barriers is an important part of the state's efforts to protect and restore fish runs negatively affected by outdated culverts under state highways. 

In 2013, a federal court injunction required the state to significantly increase the state’s efforts in removing state-owned culverts that block habitat for salmon, bull trout and steelhead.

Replacing the outdated culvert with new full-span bridge will increase the likelihood of migration through the channel. Fish will be able to pass through the creek easier as the water will be slower. The completed bridge will span a more natural creek environment. 

WSDOT will work with a Design-Build Contractor to identify efficiencies and delivery methods that will accomplish the overall project objectives with the least amount of impacts to travelers.
