Stride bus rapid transit
Creating fast, frequent and reliable transit connections north, east and south of Lake Washington

WSDOT partner and traffic impacts

Stride will connect cities surrounding Lake Washington to the regional Sound Transit 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 is partnering with cities and transit agency partners to improve infrastructure and 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 worst commutes. The I-405 Renton to Bellevue Widening and Express Toll Lanes project includes multimodal transportation and safety improvements to offer more reliable travel choices and keep drivers, transit riders and freight moving.

The Renton to Bellevue project will add new capacity to create a two-lane Express Toll Lane (ETL) system between SR 167 in Renton and Northeast 6th Street in Bellevue. In general, the project will add one new lane in each direction and combine the existing HOV lane with the new lane to create a dual ETL system.

The new ETLs will connect to the existing express toll lane 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 ETL system. This project is designed to improve speeds and trip reliability for all travelers and support the new I-405 Bus Rapid Transit (BRT) line between Lynnwood and Tukwila included in the voter-approved Sound Transit 3 package.

S2 / I-405 Brickyard to SR 527 Improvement Project

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 in added express toll lane capacity, direct access to state highways and improved connections to regional transit service at both the UW Bothell Station (SR 522) and Canyon Park Park- and-Ride (SR 527), integrating corridor investments with Sound Transit’s planned opening of the S2 Line. The Brickyard station in Bothell will be a new transit-only inline Stride station facility to support the Stride S2 line, improving connections to the existing park and ride.

The 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, and build a partial direct access interchange at SR 527 to and from the south connecting to the Canyon Park Park-and-Ride. The project will include additional local roadway improvements, fish barrier corrections, noise walls, and new stormwater facilities.

S2 / I-405 Northeast 85th Street Interchange and Inline BRT Station Project

The proposed I-405, Northeast 85th Street Interchange and Inline Station Project is located within the City of Kirkland along Interstate 405 (I-405). In partnership with the City of Kirkland, the project will replace the existing two-level cloverleaf interchange at Northeast 85th Street with a three-level interchange and construct local improvements along Northeast 85th Street and its intersection with 114th Avenue Northeast/ Kirkland Way.

S3 / 145th Street and I-5 Interchange Project

The City of Shoreline is designing improvements for the SR 523 (N/NE 145th Street) and I-5 interchange including NE 145th Street between 5th Avenue NE and the on- and off-ramps on the west side of I-5. The project will replace the signalized intersections on either side of I-5 with roundabouts and update lane configurations on the bridge over I-5.

The 145th Street and I-5 Interchange Project will improve safety and multimodal access along the 145th Street corridor and help connect to the future Sound Transit Shoreline South/148th Light Rail Station, planned to open in 2024. The interchange improvements will alleviate traffic congestion and enhance transportation mobility, reliability, and safety for all users, including pedestrians, bicyclists, transit, and freight.
