Boston University Bridge

The Boston University Bridge, located on Commonwealth Avenue in Boston, spans the Charles River connecting Boston and Cambridge. It’s notable for being one of the few bridges in the U.S. that supports both road traffic and a railway line, with MBTA commuter trains running overhead. The bridge also features a pedestrian walkway and bike path. Its historic design dates back to the early 20th century, and it’s a key crossing in the region, integrating transportation modes while offering scenic views of the river and cityscape.
