First Street Bridge

The First Street Bridge is a bascule drawbridge carrying traffic westbound over Broad Canal. The bridge suffered from several forms of deterioration including damage to the concrete counterweight, the concrete deck on the approach span, and the open metal grate deck. Under an on-call engineering service contract with the Metropolitan District Commission (now the Department of Conservation and Recreation), SGH prepared remedial designs and developed construction documents for rehabilitation of the bridge.
