Major construction is wrapping up on US 101 near Sequim. Details below in 'What to expect' section.
Project overview
This project addresses multiple barriers to fish under US 101 between Sequim and Discovery Bay.
What to expect
Construction crews are wrapping up work at three remaining sites along US 101 between Sequim and Gardiner. Workers will complete landscaping this fall and early winter.
People may notice shoulder closures during the day and intermittent overnight lane closures Monday through Thursday nights through mid-December.
Minor work remaining
When the weather is warm enough, crews will return to make a repair to the roadway near Blyn. Until that time, travelers are encouraged to reduce their speed to 45 mph in the Blyn area near Chicken Coop Road.
This project has replaced six blocking culverts beneath US 101 near Sequim between milepost 267 and 278.

Correcting fish passage barriers under US 101
The work helps protect and restore fish runs negatively affected by outdated culverts under state highways.
A federal court injunction required the state to significantly increase the state’s efforts in removing state-owned culverts that block habitat for fish.
Building bridges or fish passable structures increase the likelihood of migration. Fish will be able to pass through creeks more easily. The water will be slower. Creeks are rebuilt to simulate a more natural environment.
