Boston’s North Washington Street Bridge carries the historic Freedom Trail over the Charles River and provides a critical link between Boston’s North End and Charlestown. Originally constructed in 1898, the 1100 foot-long, 12-span bridge structure was approaching the end of its useful life. Benesch is designing a signature replacement bridge, incorporating “Complete Streets” design elements to support vehicular, bicycle and pedestrian traffic. The preferred bride-type provides a substructure with concrete V-Piers that support four lines of continuous trapezoidal steel box girders. The new replacement structure will feature two lanes of traffic in each direction, dedicated bike lanes, and 12-foot wide sidewalks. Observational sidewalk buildouts, Boston’s historic Freedom Trail, curbside plantings and other architectural appurtenances will serve to complement and further enhance the significance of the bridge’s natural and built surroundings.
