This project improves habitat and passage for fish in Purdy Creek under SR 302 and SR 16.
Purdy Creek attempts to flow under SR 16 inside 40-year-old culverts. Unfortunately, the fish cannot navigate the old culverts. This project will remove and replace the old culverts with large bridge…

Three culverts carrying tributaries to Hylebos Creek near Federal Way will be replaced with new structures under SR 161 that do not create a barrier to fish. This work builds on our commitment to remove fish barriers on streams that run under state highways.

SR 164/Auburn Way South provides primary access to the Muckleshoot Indian Reservation and growing areas of east Auburn. The Muckleshoot Indian Tribe is leading this project to reduce congestion, increase safety, and accommodate growth on the SR 164 corridor from SR 18 to the Poplar Street curve.

This project built a bridge for SR 164 over Pussyfoot Creek on the Muckleshoot Indian Reservation east of Auburn. This opens an additional 9.3 miles of habitat for salmon and other fish. The old culvert had conditions that make it difficult or impossible for fish to travel upstream.

This project makes repairs to State Route 165 south of Carbonado in Pierce County. The highway experienced settlement, dips and shoulder-drop-offs and washouts as a result of winter storm system that brought heavy rains on January 7, 2022. An emergency contract was issued for this repair work. Work…

The existing traffic signal at the Bethel/Bay/Maple intersection has reached the end of its useful life. Following research and analysis, WSDOT will replace the existing traffic signal with a modern single-lane roundabout.

Travelers on northbound State Route 167 between Puyallup and Auburn experience regular congestion, especially during morning peak commute hours. To help reduce delays during peak commute hours, WSDOT is building a new northbound high occupancy vehicle lane on SR 167. The new HOV lane will begin…

The SR 167 Completion Project in Pierce County is part of the Puget Sound Gateway Program, which also includes the SR 509 Completion Project in King County. Together these projects complete two major unfinished highways in the Puget Sound region to create new connections to Interstate 5, the ports…

The SR 167 Corridor Improvements Project is comprised of the SR 167 Toll Equipment Upgrade Project and the SR 167, SR 516 to South 277th Street Southbound Auxiliary Lane Project. As part of the SR 167 Toll Equipment Upgrade Project, we plan to update the SR 167 toll system to create consistency…

WSDOT plans to construct an additional one mile of general-purpose capacity by adding an auxiliary lane on southbound SR 167 between SR 516 and South 277th Street in Kent. The project aims to address operational challenges and will be constructed using existing shoulder pavement.

In 2021 and 2022, between Maple Valley and Black Diamond we will replace the culvert that carries Ravensdale Creek under SR 169, along with two other nearby culverts. The existing culverts are narrow, which forces the water through too quickly for salmon and other fish to continue upstream.

Reconnecting waterways where our roads act as barriers is a priority for the state. In western Washington, that means building hundreds of fish passable structures under state highways to create habitat essential for meeting fish recovery goals. Beginning in late 2024, WSDOT will begin installing…

This project will remove the existing signal at the intersection and build a multilane roundabout on SR 17 at the intersection of Grape Dr. Construction is scheduled to be complete September 2022.

SR 18 is a crucial highway connecting the south Puget Sound area with I-90, the state's main east-west route. SR 18 has experienced frequent congestion and collisions for decades.

We are receiving construction funding from the 2022 Move Ahead Washington transportation package…

In 2021 we replaced an aging concrete barrier and screens that reduce headlight glare between the eastbound and westbound lanes on SR 18 between Weyerhaeuser Way and SR 164 in Auburn.

The Samish Indian Nation is partnering with WSDOT and Skagit County to develop a practical solution to improve safety and access at the intersection of SR 20 and Campbell Lake Road.

The Deception Pass Bridge and Canoe Pass Bridge connect Whidbey Island to the rest of Washington state via State Route 20. These bridges provide the only land access on and off the island. Crews last gave these bridges a fresh coat of paint more than 20 years ago. The years of wind, sun and…

This project provides for the improvement of fish passage in two locations along SR 20 in the town of Concrete, located in Skagit County - one at Fish Creek (MP 87.82) and one at Lorenzan Creek (MP 88.78) by replacing existing culverts with two buried fish passage structures.

This project will take the existing intersection on State Route 20 at Kearney Street in Port Townsend and convert it into a single-lane roundabout.

As part of the state's fish recovery efforts, WSDOT has made it a priority to reconnect waterways where roads act as barriers. In Western Washington, that means replacing culverts and building hundreds of fish-passable structures under state highways by 2030 to create more habitat which is…

Two culverts near the intersection of State Route 202 and Northeast 124th Street between Redmond and Woodinville will be replaced with a single culvert. Two creeks in the area — an unnamed tributary of the Sammamish River and High School Creek — will be realigned to merge with the new, larger…

This project will remove the weight restrictions and restore the structural integrity of the Mabton bridges. The team has determined they will need to replace the slough bridge, while the Yakima River Bridge will be retrofitted.

After discussion and review of feedback from the…

This project improves safety along State Route 26 in Whitman County by installing shoulder rumble strips. There is a documented history of fatal and serious injury, single-vehicle, run-off-the-road crashes at these locations. Engineering analysis indicates that the installation of shoulder rumble…

This project will create three truck climbing lanes, or passing lanes, for vehicles who travel along SR 26 between Dusty and Colfax in Whitman County. One climbing lane will be built westbound and two will be built eastbound on SR 26.
