Description: The Boston Public Works Department is designing a replacement for the North Washington Street Bridge (Charlestown Bridge). Sitting in the footprint and shadows of the Zakim Bunker Hill Bridge, the replacement bridge needs to complement the form and functionality of the iconic Interstate Bridge. The key aspects of the new bridge will be that it is a livable, walkable, multimodal, green and sustainable bridge, accommodating all users, pedestrians, cyclists and motorists. The design calls for wider sidewalks, gathering places, innovative accent lighting, protected bicycle facilities, and smoother walking surfaces to support the Freedom Trail.
