### Route 90 (Snow Shuttle)

Route 90 operates when snow routes are in effect in the Central Seattle area, and when the Emergency Service Network has been activated due to severe weather. Route 90 buses travel between Downtown Seattle and First Hill, via Capitol Hill, serving all marked stops along the route from approximately 5:30 a.m. to 11:30 p.m.

### 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.

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

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