To support its transition to operating a zero-emissions fleet by 2035, King County Metro is upgrading its bus facilities in Washington County.
Work is now underway at the agency’s South Base in Tukwila to bring cleaner air to the communities needing it most.
Metro is currently constructing a test-charging facility at the base for the site’s initial battery-electric buses.
Construction will then start on the Interim Base which will support battery-electric bus operations in 2025/2026.
Next, the South Annex Base will be constructed to house up to 250 battery-electric buses. This will be one of the largest zero-emissions bus bases in the US.
This final phase of the project is currently in early stages of the design process, which will last around three years.
These expansions build upon King County Metro’s recent success in opening its first electric bus charging facility which can charge up to nine buses simultaneously.
The upgrade work to the South Base in Tukwila will allow the agency to expand its battery-electric bus operations beyond this initial deployment.
