Sound Transit, WSDOT, the City of Kirkland, and project partners celebrated the start of construction of the Stride bus rapid transit (BRT) project and the NE 85th interchange in Kirkland.

The I-405 Stride BRT project includes the S1 Line between Burien and Bellevue scheduled to open in 2028 and the S2 Line between Bellevue and Lynnwood scheduled to open in 2029. A third Stride BRT line between Shoreline and Bothell (S3) will also open in 2028.

The Benefits of Stride BRT

BRT is part of Sound Transit’s 2016 voter-approved system expansion program, ST3. Stride will provide fast, reliable high-capacity transit service with connections to light rail in Bellevue, Tukwila, Shoreline, and Lynnwood.

When Stride begins operating, trips between Bellevue and Burien will take approximately 40 minutes; trips between Lynnwood and Bellevue will take approximately 35 minutes; and trips between Shoreline and Bothell will take approximately 37 minutes. These travel times are an average of 20 minutes faster than current ST Express bus service in these areas.

“Stride will be a great new resource for transit riders, bringing more and more communities throughout the region into our high-capacity transit network,” said King County Executive and Sound Transit Board Chair Dow Constantine. “Launching this project is another step toward delivering on the vision voters approved with ST3 and will be an exciting step forward for the Puget Sound region.”

Improving Transit Access

As part of the I-405 BRT project, Sound Transit and WSDOT are building a redesigned NE 85th interchange, which will include an inline Stride station. The redesigned interchange will allow for improved transit access and direct access to express toll lanes, improving speed and reliability for I-405 travelers.

The interchange and BRT stop will open in 2026, before the S1 Line, to serve existing transit routes. Other elements of the project include pedestrian and bike access, a passenger pick-up and drop-off area, new stops for local transit service, and express toll lane direct access ramps.

“A sustainable and equitable transportation network gives all our communities a wide range of mobility opportunities to meet our wide-ranging connection needs,” said Sound Transit CEO Julie Timm. “Stride BRT is an integral piece of our expanding and interconnected regional transit system being built to bring more people to more places more effectively and more efficiently.”
