The Silver Spring Transit Center has taken a crucial step forward, with Montgomery County officials opening the project for construction bids.

The three-level structure, to be built on the stretch of pavement adjacent to the Silver Spring Metro Center, is slated to include space for Metrobuses, Ride On buses, taxis, Kiss ’N Ride drop off, and connections to the MARC and Metro stations. It also will make room for an intercity bus service such as Greyhound.
