Metro - your mobility agency

King County Metro is creating a world-class, integrated public transportation network with far-reaching and innovative solutions to help build healthy communities, a thriving economy, and a sustainable environment.

Mobility is a human right

For Metro, mobility means the ability to get where you need to go, when you need to—safely, equitably, and sustainably.

Our mission

Our mission is to provide the best possible public transportation services to improve regional mobility and quality of life in King County.

King County’s communities and geography are diverse, so we are designing a mobility network that connects people to opportunities and knits together our growing communities. We are committed to eliminating disparities by race and place, and prioritizing service where the needs are greatest.

We are the largest bus network in the region, and we are reducing greenhouse gas emissions to improve and protect our air quality. Metro is leading the transit industry—and the country—in moving to a 100% zero-emissions fleet by 2040.

To meet the increased service needs for our growing region, we will improve and expand our current bus bases and build new ones. Metro’s facilities will be constructed to be consistent with the highest green building and sustainable development practices, and will provide local job opportunities.

By developing a mobility network that supports livable communities, a thriving economy, and a sustainable environment, we can all move forward together.


It is our commitment to you to provide the best possible public transportation services and improve regional mobility.
