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.
Our construction and maintenance crews will make improvements to sections of US 101, US 12, State Routes 104, 109, 112 and 116. People will travel through multiple work zones that may have reduced speeds and shifted lanes with temporary traffic lights.
Give yourself extra time to help prevent delays.

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 work zones planned on state highways in Jefferson and Clallam counties. Timing of projects are subject to change.
SR 104 – Hood Canal Bridge – Center Lock Rehabilitation
Construction timeline
Spring 2026 - Summer 2026
What can travelers expect?
In the late spring and summer of 2026, travelers will see overnight bridge closures from 11 p.m. to 4 a.m. as work continues on the bridge’s shock absorbers.
Work also continues on the bridge’s center lock system. Travelers may see short maintenance openings lasting 30 to 40 minutes during daytime hours.
When specific closure dates are scheduled, please visit the project webpage or the Hood Canal Bridge status page.
The video below shares more about why the SR 104 Hood Canal Bridge needs ongoing preservation.

This project replaces an outdated culvert along US 101 south of Forks identified as a barrier to fish migration. Crews have completed a 175-foot-long concrete girder bridge that replaces a 9-foot diameter metal pipe. Travelers will continue to see single-lane alternating traffic at the Jefferson-Clallam county line while crews rebuild the stream under the highway. The speed limit is reduced to 25 mph through the work zone.
Visit the project webpage for more details.
In late September 2025, crews completed the new bridge over May Creek.
US 101 E of May Creek – Emergency Repair
Contractor crews build a soil nail wall next to the northbound lane of US 101 in Jefferson County near Dowans Creek Road. The emergency repair will stabilize the slope above the Bogachiel River.Construction timeline
February 2026 – Fall 2026
What can travelers expect?
Travelers will see one-way alternating traffic controlled by a signal around the clock until permanent highway repairs are made. A 25 MPH speed limit remains in place. The timeline for the permanent repairs is not yet finalized.
Visit the project webpage for more details.
US 101/Grader & Unnamed Trib to Pac Ocean- Remove Fish Barriers
Construction timeline
Spring 2025 – Fall 2026
What can travelers expect?
This project replaces two outdated culverts under US 101 in Jefferson and Clallam counties that are identified as a barrier to fish migration. Travelers will see reduced speed limits and one-way alternating traffic controlled by traffic signals at each work zone. In summer 2025, crews built a new bridge at each site that will allow fish to swim freely under the highway. In summer 2026, crews will rebuild the streambeds under the highway.

Construction timeline
Late Winter 2026 - Fall 2026
What can travelers expect?
Alternating one-way traffic controlled by a signal is in place at milepost 165 near the Olympic National Park Ruby Beach entrance. The highway experienced erosion along the shoulder during December 2025 winter storms. Maintenance crews continue to monitor the location. A permanent repair is being scheduled. We will share more information on this once it becomes available.

SR 104 – Paradise Bay – Shine Road – & SR 19 Intersection Safety Improvements
Construction timeline
Spring 2024 - Fall 2026
What can travelers expect?
Both roundabouts are complete and open to traffic. The meter at SR 104 and Paradise Bay Road has been installed. It will be turned on sometime in 2026 after traffic camera installation.
Visit the project webpage for more details.
The video below shows how the opening and closing of the Hood Canal Bridge plays a role into the design and operations of the roundabout.
SR 112 E of Sail River to E of E Twin River – Paving and Preservation
Construction timeline
Summer 2026 - Fall 2026
What can travelers expect?
Crews will return after the 2025/2026 winter to do some roadway patching. In the summer of 2026, crews will complete final paving and guardrail installation. Paving work will begin in mid-August. Crews will pave from milepost 0 near the Sail River to milepost 7.
Grays Harbor County
Here is a list of projects that will be active 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.

SR 109 - Ocean City to Taholah – Remove Fish Barriers
Construction timeline
Spring 2026 to Fall 2027
What can travelers expect?
This project replaces outdated culverts under State Route 109 at five locations on the Quinault Indian Nation with bridges or larger culverts. Travelers will see flaggers or temporary traffic lights alternating traffic on a single lane through fall 2026. The speed limit will be reduced to 25 mph through the work zones. At some sites, travelers will see occasional closures of the highway up to 45 minutes. The closures allow crews to deliver large materials for bridge construction. Crews expect to complete work at two sites in fall 2026. All sites will return to one lane open in each direction with work stopping for winter. Crews will return to the other three sites to complete construction from spring through fall 2027.

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.
Learn more in the latest Fish Passage Annual Report (PDF 9.3MB) and our YouTube video on fish passage restoration.
