Abstract: The lower level of the Broad Street Bridge, which dates to 1823, was an aqueduct which carried the Erie Barge Canal over the Genessee River in Rochester, New York. The history of this structure parallels the development of transportation in the Northeast - water-borne, rail, automobile. In 1924 an upper deck of reinforced concrete was added to carry vehicular traffic, and the stone lower level was converted to railway use. In 1971 deterioration of the upper level necessitated its reconstruction. It was imperative that one half of the bridge remain open to traffic during reconstruction. Precast, prestressed concrete units were selected for the new deck. This landmark structure was rehabilitated within an acceptable schedule with minimum inconvenience to the public.
