People who use the interchange at I-5 and SR 523 (North 145th Street) in Shoreline need safe and efficient ways to move through this area, using all modes of transportation. This will be increasingly important with the arrival of Sound Transit Link light rail and the new Shoreline South/148th…

This project will remove a fish passage barrier along Thornton Creek under Interstate 5 near State Route 523/NE 145th Avenue in Shoreline. Contractor crews working for WSDOT will replace the two existing 2,000-foot-long, 6-foot culverts with three fish-passable structures. The current culverts are…

This project will remove three barriers to fish passage along two Unnamed Tributaries to Silver Lake and an Unnamed Tributary to Penny Creek under Interstate 5 near 112th Street Southeast in Everett. Contractor crews working for WSDOT will remove existing culverts and replace them with fish-…

We will rehabilitate I-5 between Yesler Way in Seattle and the Northgate vicinity with new concrete panels, pavement, expansion joints and deck repaving on the Lakeview viaduct and Lake Washington Ship Canal Bridge. This project will be advertised for contractors in summer 2023. Work will start in…

This project adds capacity for both directions of I-90 between Eastgate and West Lake Sammamish Parkway interchanges by restriping the roadway and adding an auxiliary lane. Crews also built sound walls in strategic locations to minimize traffic noise.

The pavement conditions within the limits of this project on I-90 have fallen below an acceptable rating. This project will rehabilitate the roadway along this section to preserve the pavement and pavement structure.

This project will rehabilitate roughly 13 miles of Interstate 90 from Ritzville to approximately five miles east of Sprague Lake in Adams County. Once the project is completed by grinding and inlaying new HMA (Hot Mix Asphalt), the roadway surface will have a smoother ride that will be preserved…

Phase 3 is part of a 15-mile corridor improvement project to improve safety and reliability and reduce congestion along I-90 from Hyak to the Easton vicinity. We are increasing traffic capacity and improving safety by adding a new lane in each direction, replacing concrete pavement, stabilizing…

Phase 1 was part of a 15-mile corridor improvement project to improve safety and reliability and reduce congestion along I-90 from Hyak to the Easton vicinity.

Phase 2 was part of a 15-mile corridor improvement project to improve safety and reliability and reduce congestion along I-90 from Hyak to the Easton vicinity.

Phase 4 is part of a 15-mile corridor improvement project to increase safety and reliability and reduce congestion along I-90 from Hyak to the Easton vicinity.

The I-90 Snoqualmie Pass East Project improves 15 miles from Hyak to Easton. Phases 1 and 2 from Hyak to the Stampede Pass interchange are complete. Phase 3 is underway.

As part of the state's fish recovery efforts, WSDOT has made it a priority to reconnect waterways where our roads act as barriers. In western Washington, that means building hundreds of fish passable structures under state highways in the next decade to create habitat gain essential for…

Several projects funded through Connecting Washington and partner funds will address the improvement needs on Interstate 90 at the Barker Road interchange, the Harvard Road interchange and local network connections.

Multiple bridge decks have fallen below an acceptable rating. This project will rehabilitate the bridge decks by patching potholes and replacing fatigued sections of bridge decks.

In Spring 2022, contractor crews working for WSDOT will begin replacing the 38 steel anchor cables on the Lacey V. Murrow and Homer M. Hadley Memorial floating bridge across Interstate 90. Work is expected to be complete this fall.

Due to significant growth on the West Plains, three new roundabouts will be constructed at the Geiger/Grove Road interchange with I-90. The reconfigured interchange at Geiger Boulevard and I-90 will provide for more efficient vehicle movement. Improvements include interchange ramp terminal…

This project sets out to reduce the risk and severity of run-off-the-road collisions throughout the highway corridor by removing vertical rock cuts and outcrops from the median or by shielding the rock with barrier.

The SR 902/Medical Lake interchange reconstruction project is located at the existing State Route 902 interchange with I-90 at exit 272 west of Spokane. This project includes the construction of three roundabouts, a new parallel bridge over I-90 and a shared-use path that will connect to the West…

This project will rehabilitate the deteriorating concrete bridge deck for the Mullan Road Bridge over I-90. Crews will remove approximately 1.5 inches of existing concrete through hydro-demolition. Once removed, existing reinforcing steel that is exposed will be evaluated to determine the need and…

Several blocked culverts below Interstate 90 and State Route 202 in east King County are a barrier to fish migration and will be replaced with new, larger culverts beginning in 2025. Contractor crews working for WSDOT will replace three culverts under I-90 in Preston and one culvert under SR 202…

Several new ramp meters have been implemented and activated throughout Spokane at on-ramps to both east and westbound I-90 with more coming. The ramp meters are used to space out vehicles as they enter I-90 to reduce the "platooning" of vehicles as they enter and reduce collisions. The…

Contractor crews will repave roughly eight miles of Interstate 90 from the Tokio interchange to the Lincoln County line during the summer of 2021.

This project replaces the existing bridge deck on the I-90 Vantage Bridge to maintain the structural integrity, ensure the safety of the highway and extend the life of the bridge. The Vantage Bridge was built in 1962 and the last time the bridge received a major overhaul was in 1982.

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 2024, WSDOT will build multiple…
