Biddeford Saco Old Orchard Beach Transit, or BSOOB Transit, is the primary provider of public transportation in the Tri-Town area of Maine, just south of Portland. It operates a system of fixed bus routes in Biddeford, Saco, Scarborough and Old Orchard Beach, an express commuter bus service that connects the Tri-Town area to downtown Portland, and seasonal trolleys that serve tourist destinations in the area. Many of the system’s routes connect to the agency’s hub at the Saco Transportation Center, which opened in 2019. Along with the Greater Portland Metro Bus and the South Portland Bus Service, BSOOB Transit accepts fares electronically via the DiriGO TouchPass system.
