Route Improvements

STBD generates over $50 million dollars annually, and the bulk of this revenue is used to pay for more trips on King County Metro routes throughout Seattle. In total, about 79 cents of every dollar collected through the program is used to increase frequency on popular routes, extend the span service (i.e. the hours during which a route operates) for key bus connections throughout the city, and address trips that are chronically overcrowded.

STBD Spending Breakdown

Improving Service, Year over Year

Since the program began in 2015 until now, we have added more trips on more routes throughout Seattle every single year. While the bulk of STBD-funded service was added within the first year of the program, as revenue has increased and more investment capacity has been made available, we have continued to increase the number of routes that meet our various policy goals, while responding to the changing demands of Seattle's traveling public.

King County Metro makes service additions and/or changes twice per year - once in March and once in September (in 2015 and earlier, service could be adjusted in June as well). See below how we have continued to improve service along this timeline since the beginning of the program.
