RapidRide Expansion in Seattle

Last updated: September 13, 2017

Seattle is one of the nation's fastest-growing cities with ever-increasing demands on our transportation system. SDOT is working with King Country Metro to improve the RapidRide transit network throughout our city, planning seven new lines to help better connect people, places, and products.

Program Description

The RapidRide Expansion Program is a partnership between the City of Seattle and King County Metro to deliver convenient, high-quality mobility options to Seattle's growing population through the implementation of seven new RapidRide corridors.

Through a combination of service improvements, capital investment, and design treatments, these corridors build on the success of existing Metro RapidRide service and help meet the goals and vision of local and regional planning efforts. RapidRide design considers the unique needs and context of each location. In addition to the transportation plans that inform it (like the King County METRO CONNECTS and City of Seattle PedestrianBicycle, and Freight Master Plans), development is shaped by transit performance data, agency partnerships, and public input.

Metro RapidRide will connect major destinations and link diverse and growing neighborhoods with employment, shopping, and transit hubs. The network will serve areas of the city where large numbers of people work and live. By 2035, approximately 1.5 million jobs and almost 650,000 residents will be located within half a mile of a new RapidRide corridor. With such convenient, comprehensive service, over 50,000 additional daily trips are expected on the RapidRide network in Seattle by 2035.

Project Funding

The nine-year, $930 million Levy to Move Seattle provides partial funding for the RapidRide Expansion Program, along with funds for other projects to improve safety for all travelers, maintain streets and bridges, and invest in reliable, affordable travel options for a growing city.

SDOT will work with King County Metro to pursue grant funding programs and other partnership opportunities to stretch taxpayer dollars to cover the full cost of the program.

How can I get involved?

We’ll be working with communities during the planning, design, and construction phases of each new RapidRide line. For each new line, we’ll share data, ask for your feedback, and show how community input has been incorporated into the design.
