Stride will connect communities surrounding Lake Washington to the regional Link light rail system and to other transit services provided by King County Metro and Community Transit. To prepare for Stride service in the region, Sound Transit has partnered with the Washington State Department of Transportation (WSDOT), neighboring jurisdictions, and other transit agencies to build new infrastructure and improve transit connections.
S1: I-405 Renton to Bellevue Widening and Express Toll Lanes Project
Travelers on I-405 between Renton and Bellevue experience one of the state’s roughest commutes. The I-405 Renton to Bellevue Widening and Express Toll Lanes Project includes transportation and safety improvements for different modes to offer more reliable travel choices and keep drivers, transit riders, and freight moving smoothly through the region. This project is designed to improve speeds and trip reliability for all travelers and shorten Stride S1 Line travel times between Renton and Bellevue.
This project will construct a new two-lane express toll system between SR 167 in Renton and NE 6th St in Bellevue by adding one new lane in each direction and combining the existing HOV lane with the new lane to create the two-way express toll lane system. The new express toll lanes will connect to the existing express toll system between Bellevue and Lynnwood — as well as the SR 167 HOT lanes via the I-405/SR 167 Interchange Direct Connector — to create a 40-mile express toll lane system.

S2: I-405 Brickyard to SR 527 Improvement Project
The I-405/Brickyard to SR 527 Improvement Project will enhance 4.5 miles of the corridor with a focus on both the main project expansion and overall operational improvements.
The project will…
- Build one new express toll lane in each direction between south of SR 522 and SR 527 (extending the existing dual express toll lane system).
- Widen I-405 through the SR 522 interchange and build direct access ramps to the express toll lanes at SR 522.
- Build a partial direct access interchange at SR 527 to and from the south connection to the Canyon Park Park-and-Ride Lot.
This project will also include additional local roadway improvements, fish barrier corrections, noise walls, and new stormwater facilities.
The I-405/Brickyard to SR 527 Improvement Project lies primarily in Bothell on I-405, starting just south of the SR 522 interchange and ending at the SR 527 interchange. The communities in this vicinity will see major improvements to express toll lane capacity and direct access ramps to state highways. The project will also improve connections to regional transit and Stride bus services. A new transit hub at the UW Bothell/Cascadia College campus will serve as a transfer option between the Stride S2 and S3 lines. Community Transit and King County Metro will also use this hub, making it easier than ever to transfer between transit providers and travel to more destinations. This project will construct new Stride stations along I-405 near the Canyon Park Park-and-Ride Lot (SR 527) and a new inline station at NE 160th St (Brickyard Road).

S2: I-405/Northeast 85th Street Interchange and Inline BRT Station Project
The I-405/Northeast 85th Street Interchange and Inline BRT Station Project runs along I-405 within the City of Kirkland. In partnership with the City of Kirkland, the project is replacing the two-level cloverleaf interchange at NE 85th St with a three-level interchange and making local improvements to NE 85th St and its intersection with 114th Ave NE/Kirkland Way.

S3: 145th Street and I-5 Interchange Project
The 145th Street and I-5 Interchange Project will improve safety and access for multiple modes of transit along the NE 145th St corridor and help connect to Sound Transit’s Shoreline South/148th Station. The roundabout and interchange improvements will alleviate traffic congestion and enhance transportation mobility, reliability, and safety for all users, including pedestrians, bicyclists, transit vehicles, and freight.
