Greyhound Lines formerly ran extensive intercity service in Washington state that was cut in 2004 as part of a regional restructure to focus on profitable routes. In 2007, the Washington State Department of Transportation began planning for an intercity bus network pilot project.
The first Travel Washington bus route to open was the Grape Line, which began service in December 2007. It was also the first bus service to be funded through a private-public partnership between the Federal Transit Administration and private operators, with the former matching the latter's investments with grant money.
Travel Washington consists of 4 routes connecting major cities in Washington to other intercity transit services offered by Amtrak, Greyhound and Northwestern Trailways, as well as regional airports in Seattle and Pasco. Most stops are sited at major transfer points with local bus systems.
