Budget Information

SR 112 - Nordstrom Creek - Remove Fish Barrier

Status

October 2017

  • Crews are currently building a single-lane detour at the stream site just east of Dempsey Road. Detour construction will occur weekdays from 7 a.m. to 6 p.m. through July, during which time drivers will encounter one-way alternating traffic with flaggers.
  • When the detour is complete, traffic will be shifted onto the temporary roadway and drivers will experience one-way alternating traffic around the clock until the project is completed in late summer.

 

Why is WSDOT replacing the culvert under State Route 112?
WSDOT will install a new box culvert under SR 112 to improve fish habitat in Nordstrom Creek. Replacing the culvert will make the stream more maneuverable for migrating fish, extending usable habitat.

This work is part of WSDOT's Fish Passage Barrier Removal Program, which identifies and removes barriers to fish passage caused by 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 and steelhead.

WSDOT has a responsibility to be a good environmental steward. This culvert runs under a state highway. It must be replaced to eliminate the barrier it poses to fish.

The End Result
This new structure will open up approximately 3 miles of habitat for fish passage in Nordstrom Creek.

In addition, the work will help preserve the integrity of the highway and reduce maintenance costs by reducing or eliminating the possibility of the blockages.

Project Benefits
This project will replace an outdated culvert that is a barrier for fish with a culvert that is built wider than the existing stream channel. The new culvert and restored creek channel simulates what is found in a natural stream bed.

What is the project timeline?

  • Summer 2017 - Construction begins.
  • All in-stream work will occur in late summer to meet environmental requirements and accommodate fish windows.
  • Traffic control is expected to be complete by mid- to late-September. 
  • Fall 2017 - Project complete.
