Moving forward together

One of King County’s great advantages to residents and visitors is a public transit system recently recognized as the best in North America. Wherever you need to go, you can get there by bus, light rail, paratransit van, rideshare, streetcar, water taxi, or new flexible options.

In his dual role as the executive in charge of King County Metro and a member of the Sound Transit Board of Directors, Executive Constantine helped create today’s seamless regional transit network by directing the agencies to better integrate their services.

In the years ahead, continuing to expand and improve our transit network will strengthen our economy, connect even more people to opportunity, protect our environment, reduce congestion, and support healthy communities.

Under the leadership of the executive, Metro is driven by its values of safety, equity, and sustainability.


The number one priority is the safety of passengers, transit employees, and communities. In early 2020, our regional transit network safely delivered more than 400,000 daily trips on Metro and another 100,000 on Sound Transit.

Our transit system was also the first in the country to respond to COVID-19 and quickly implemented an array of health enhancements guided by experts. Metro is committed to continuous improvement and is constantly examining new practices and technologies.


Driven by the belief that mobility is a human right, Metro prioritizes service where needs are greatest. Metro’s Mobility Framework, which guides the agency’s pro-equity approach, received the Innovation Award for Equity and Social Justice from Executive Constantine.

Metro’s dedication to equity is evidenced also by a fare model that provides discounted or free trips to customers with disabilities, residents with low incomes, seniors, and youth, and by the nearly one million trips delivered each year by its Access paratransit service.


Transit is one of the greenest forms of transportation in our region. Metro takes the equivalent of 190,000 cars off the road every day and has an annual net reduction of 600,000 metric tons of carbon per year. Public transportation reduces pollution locally and combats the climate crisis globally.

Metro retired its last diesel-only bus in 2020 and its first order of next-generation battery-electric buses will start serving customers in spring 2021. In support of King County’s Strategic Climate Action Plan (SCAP), Metro fully transition to a zero-emission fleet by 2040 or sooner.
