BOSTON- BRIDGE REPLACEMENT, B-16-020=C-09-004, CHELSEA STREET OVER THE CHELSEA RIVER

The proposed vertical lift bridge will be a truss type structure that spans 450 feet from bank to bank and will provide 175 feet of vertical clearance in the raised position. The bridge and approach roadway match the footprint of the existing bridge and will provide for four lanes of traffic (two in each direction) and two pedestrian sidewalks. Approach roadways will be reconstructed as needed to meet the existing local streets. A complete warning signal and gate system will be provided at the approach roadways. The warning gate and bridge traffic signal operations will be interconnected with the Central Avenue/Marginal Street/Eastern Avenue intersection in Chelsea to provide for continuous traffic operations in the intersection during bridge openings.
