Welcome to our online open house!
Travelers headed to Washington’s Pacific Ocean beaches or around the Olympic Peninsula will need to add extra travel time.
This year, our construction and maintenance crews will make improvements to sections of US 101, US 12 and State Routes 8, 104, 112 and116 and in Grays Harbor, Mason, Jefferson and Clallam counties. People will travel through multiple work zones that may have reduced speeds and shifted lanes with temporary traffic signals.
To help plan and navigate work zones around the Olympic Peninsula, we invite you to explore this online open house. Construction work zones are sorted by county.
Clallam and Jefferson Counties
Here are the 2025 work zones in Jefferson and Clallam counties located on state highways. Give yourself extra time to help prevent delays. Timing of projects are subject to change. WSDOT will update this online open house as new information becomes available, so be sure to check back here before you travel.

What can travelers expect?
Construction crews will continue work at three locations along US 101 in 2025. Two are located between Sequim and Blyn. The third is located near Gardiner off Discovery Bay.

WSDOT built a new bridge to improve fish passage and wildlife connectivity in Sequim. The vantage point looks northeast and includes Sequim Bay Lodge to the left of the road and the Olympic Discovery Trail to the right.All locations have a two-lane bypass road around each work zone. Travelers will see reduced speed limits and shifted lanes with occasional nighttime one-way alternating traffic.
People riding bicycles or walking will follow temporary detours using the Olympic Discovery Trail between Blyn and Sequim.
The intersection of US 101 and Whitefeather Way is closed through summer 2025.

What can travelers expect?
This project replaces an outdated culvert along US 101 south of Forks at May Creek identified as a barrier to fish migration. The culvert currently runs under the roadway at the Jefferson-Clallam County line. A 175-foot-long concrete girder bridge will replace the existing 9-foot diameter metal pipe. A temporary single lane bypass road, temporary bridge and associated traffic signals will remain in place until construction of the permanent bridge is complete. The speed limit is reduced to 25 mph through the work zone.

Construction timeline
Spring 2024 – Fall 2025
Project webpage: https://wsdot.wa.gov/construction-planning/search-projects/us-101-northwest-us-101-remove-fish-barriers
What can travelers expect?
This project replaces five outdated culverts under US 101 in Jefferson and Clallam counties that are identified as a barrier to fish migration. Four sites between Ruby Beach and the Jefferson-Clallam county line were completed in 2024. Crews will return in late spring/early summer 2025 to complete a new bridge at the final site located near Wisen Creek Road east of Forks. Travelers will encounter one-lane alternating traffic with a temporary signal and a reduced 25 mph speed limit until the project is complete in fall 2025.
US 101 Elwha River Bridge – Bridge Replacement
Construction timeline
April 2023 – Summer 2025
Project webpage: https://wsdot.wa.gov/construction-planning/search-projects/us-101-elwha-river-bridge-bridge-replacement
What can travelers expect?
The new bridge is open to traffic and all of the engineered logjams have been installed. Remaining work includes demolition of the old bridge this summer.
Why is this work needed?
The bridge was built in 1926 and has served the community for nearly 100 years. Replacing the bridge will ensure that the US 101 route continues to be a reliable transportation facility for decades to come.

Grays Harbor County
Here is a list of projects that will be active in 2025 in Grays Harbor County. Timing of projects are subject to change, and we will update the contents of this online open house as new information becomes available.
US 12-SR 8 – Grays Harbor Fish Passage Barriers – Remove Fish Barriers
Construction timeline
Summer 2023 to Summer 2025
Project webpage: https://wsdot.wa.gov/construction-planning/search-projects/us-12-sr-8-grays-harbor-county-fish-passage-barriers-remove-fish-barriers
What can travelers expect?
This project replaces five culverts under US 12 and SR 8 that are barriers to fish migration. Travelers will see a 50-mph speed limit and reduced lanes. Travelers can expect occasional rolling slowdowns throughout spring and summer. The rolling slowdowns allow crews to quickly deliver materials to the work zone. Once paving and striping is complete, travelers will see two lanes open on each side of the highway. Throughout fall, travelers will see daytime lane closures until all work is complete.

Spring 2025 to Fall 2025
Project webpage: https://wsdot.wa.gov/construction-planning/search-projects/us-101-quinault-indian-nation-remove-fish-barriers-pdb1-b3
This project replaces six outdated culverts between Lake Quinault and the Queets River. Travelers will see five work zones in Grays Harbor County and one in Jefferson County just north of the county line. All work zones will have alternating one-way traffic on a temporary bypass road controlled by traffic signals.
Mason and Thurston Counties
US 101/Skookum Creek Br to N of Jct SR 8 – Paving
Construction timeline
Summer 2025 to Fall 2025
This project will remove and replace worn sections of pavement along approximately seven miles of US 101. Travelers will see single-lane closures between milepost 353 in Mason County and milepost 362 in Thurston County. The speed limit will be reduced from 60 mph to 45 mph in the work zone.
Why construction is happening
The work zones are necessary to maintain the movement of people and goods across the peninsula and Hood Canal. They include projects that are related to WSDOT’s fish passage program. There are also critical projects and ongoing maintenance occurring to keep bridges operational and pavement up to standards. This work helps improve the resiliency of our highways.
Fish Barrier Removal Program
A fish passage barrier is anything that hinders fish from moving. Culverts, large pipes under roadways, allow water to flow but may not allow fish to swim through. Water might be too swift, too shallow, or has a waterfall into or out of the culvert.
We correct fish barriers on state highways to help salmon recovery. WSDOT also must follow with state laws. A federal court injunction also requires correction of barrier culverts to help fish.
