North Station Draw 1 Bridge Replacement

The North Station Draw 1 Bridge traverses the Charles River to connect Boston’s North Station to the Massachusetts Bay Transportation Authority’s (MBTA) commuter rail. The MBTA selected STV to provide engineering design services to replace the existing bridge spans with a new, six-track crossing. The firm services include the design of movable bridge spans, a replacement signal tower, a new pedestrian walkway, subsequent track and signal work, and the addition of two platform tracks at North Station.

To help alleviate costs, the firm designed shorter bridge spans over the channel. Once complete, the six tracks across the Charles River will allow for an increase in the number of platforms available for passenger service as well as improved train traffic flow, all while providing the same vertical clearance to boats passing through.
