Description: The Long Island Bridge, which carried traffic from Moon Island to Long Island, has been closed to vehicular and pedestrian traffic since October 8, 2014. The Boston Public Works Department, with Walsh Construction as its contractor, has executed a contract to demolish the existing bridge. The bridge is 16 spans and 3,450′ in length and also carried utilities to both Long Island and Spectacle Island. The demolition contract will include taking down the bridge, as well as the relocation of utilities to the seabed. The current timeline calls for the demolition of the bridge to be completed by April 30th, 2015, with the installation of utilities to be completed by June 15th.
Neighborhood: Charlestown/North End
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.
