4-3-25 Fish Barrier Construction – Bicycle Routing

Hello from the Washington State Department of Transportation,

As summer approaches, we want to remind you about temporary changes for some pedestrians and bicyclists using US 101. While we completed several fish barrier removal projects in 2024, we have more work ahead of us this construction season. There are two locations between Gardiner and Sequim where bicyclists and pedestrians are detoured onto the Olympic Discovery Trail.

People on bicycles or walking from Blyn to Sequim will detour onto the Olympic Discovery Trail. US 101 will remain open for people heading from Sequim to Blyn.

Detour map for bicyclists and pedestrians going from Gardiner to Blyn.

Both detours will continue until late summer 2025. More information is available at the project webpage.

We would greatly appreciate your help in getting the word out!

Also, this summer, whether heading to the Hoh Rainforest or windswept Pacific Ocean beaches, travelers will see some additional views: orange cones and multiple work zones.

The Washington State Department of Transportation will have multiple fish habitat, safety and preservation projects under construction on six state highways in four counties.

To help travelers prepare for the construction, WSDOT has an online open house highlighting 12 projects on US 101, US 12 and State Routes 8, 104, 112 and 116 and in Grays Harbor, Mason, Jefferson and Clallam counties.

Please let us know if you have any questions.
