SEQUIM — A set of roadwork projects along U.S. Highway 101 to remove barriers to fish is about halfway completed, state Department of Transportation officials said, with more projects expected to affect highway traffic well into the fall.

The projects, slated through fall 2025, kicked off with a culvert replacement at Eagle Creek near Gardiner that is now complete.

This summer, work moved to Discovery Creek in Sequim and Chicken Coop Creek in Blyn.

State workers installed two active two-lane bypass roads near West Sequim Bay Road at milepost 268.5 and near Deerhawk Drive at milepost 271.9, respectively, allowing crews to replace culverts with minimal traffic impacts.

Travelers are now using new highway bridges at both locations.

“It’s a common tool we use during this type of work,” state officials said in their blog (wsdotblog.blogspot.com/2024/08/us-101-fish-passage.html). “While we dig up the highway, people use a two-lane bypass road next to the work zone. We’re keeping people moving while we remove barriers to fish.

“Correcting these barriers is an important part of the state’s efforts to restore salmon runs, ultimately benefiting both the Pacific Northwest landscape and economy.”

In April, work began on the bridge at Contractor’s Creek. Crews have temporarily widened U.S. Highway 101 to shift travelers away from the work zone. The shifted lanes will stay in place until next spring, transportation officials said. The work along Discovery Bay will continues through fall 2025.

Later this summer and fall, construction will begin on the final two fish barriers in the project — Johnson Creek near Sequim as well as a stream in the Blyn area.

Johnson Creek will require a closure to left turns at the intersection of Whitefeather Way and U.S. Highway 101; there will be no left turns to or from the highway and Whitefeather Way from September through June 2025.

Vehicles accessing the John Wayne Marina or the Olympic Discovery Trail parking lot on Whitefeather Way will detour along West Sequim Bay Road.

“We’re restricted to a short time when we can do this type of work,” Department of Transportation officials said.

“This window is usually July through September. We do a lot of other work outside this fish window.”

State transportation crews will use a two-lane bypass to keep people moving through the work zone because of the proximity of the work zone to Whitefeather Way.

In addition, the project will require a temporarily closure of Whitefeather Way at U.S. Highway 101, state officials said, an estimated two-week closure scheduled for spring 2025.

“We understand it is an inconvenience; we work to keep intersections open when possible,” state officials said in their blog. “However, this task will require the temporary closure. We’ll let you know when the closure is scheduled.”

Portions of U.S. Highway 101 are detoured onto the Olympic Discovery Trail.
