BOSTON- BRIDGE REHABILITATION, B-16-016, NORTH WASHINGTON STREET OVER THE CHARLES RIVER
The North Washington Street Bridge is a historic structure constructed in 1898. The bridge consists of 10 approach spans and a swing span, which is not operational. The bridge is structurally deficient and is posted for restricted loads. There have been extensive emergency repairs done to the bridge in the past few years. Currently the two center lanes on the swing span are closed due to steel deterioration. The City of Boston proposes to rehabilitate the bridge. On the approach spans this rehabilitation will include replacement of the existing concrete deck slabs and sidewalks with lightweight reinforced concrete and replacement of all deteriorated structural steel, which will amount to approximately 37% of all floor beams and 50% of all stringers. At the swing spans, the rehabilitation will include replacement of all floor beams and stringers and replacement of the open metal grating with an Exodemic deck with lightweight concrete. Also proposed is the complete deleading and repainting of the entire structure.
