Route 97 (Link Shuttle)

King County Metro operates Route 97 when service on Sound Transit's 1 Line is suspended for a prolonged period of time. If the entire line is closed, Route 97 buses emulate trains, stopping at every station along the line. If only a section of the line is closed, Route 97 buses serve as a "bus bridge" shuttling passengers between the operating sections of the line and stopping near intermediate stations on the closed section of the line, in the case of a multi-station closure. Limited stop variants of route 97 may also be operated in the case of a multi-station closure.^[3]

600s (Community Shuttle and Trailhead Direct)

This series of numbers is used for routes considered temporary or experimental. Currently community shuttle routes use these numbers. These routes are operated using Metro owned minibuses, operated by drivers from the non-profit Hopelink and partially funded by the communities they serve. While all routes operate on a fixed route, they also offer a flexible service area where passengers can be picked up and dropped off, if they make a reservation in advance.

The 600s are also used for the Trailhead Direct shuttle system, which runs on weekends and holidays during the spring and summer.^[6]

During the winter months (late October to early April) mid-day and weekend service is suspended on the West Seattle Water Taxi and on the shuttle routes.

Routes in the 700s are also used for special event services, such as Washington Huskies football games at Husky Stadium.^[8]
