      The Charles River Bridge is a pair of railroad single-leaf, through-truss, rolling bascule bridges across the Charles River that connects North Station in Boston, Massachusetts to MBTA Commuter Rail lines in northern Massachusetts.

      Design and construction

      These bridges were designed by Keller & Harrington of Chicago, Illinois and built by the Phoenix Bridge Company of Phoenixville, Pennsylvania. Each bridge uses a 629-short-ton (571 t) over-head concrete counterweight. Originally, there were four bridges, but only two of them remain.[1]
