Major Projects

In 2018, in the midst of an historic service expansion, TriMet purchased property for a new bus garage at 4421 NE Columbia Boulevard, in Portland. This site is well-situated in an industrial area within TriMet’s service district, allowing buses to begin and end their routes close to their home base and minimize their time in traffic.

The site includes some buildings that could be refurbished, and others that may need to be replaced. Due to the ridership reduction caused by the pandemic, full redevelopment of the site has been paused. In the meantime, the site is being used for bus parking, storage and office space. A primary activity is receiving new buses — including electric buses — to perform safety inspections and prepare them for testing and service. Details about further site redevelopment will be informed by TriMet’s ridership growth, service expansion and transition to zero-emission buses.
