When rail service ended in Troy on July 27, 1963, it was converted for automobile traffic. Until then the northern span was a rail bridge, and the southern span was a toll bridge for cars, trolleys, and pedestrians. It had a lift span added in 1924-25 for river shipping. This bridge failed on March 15, 1977 due to flooding caused by 2.7 inches (69 mm) of heavy weekend rains, coupled with melting snows and heavy runoff. The flood-induced scour undermined the lift span pier, causing the western lift tower and roadbed span of the bridge to collapse into the Hudson River.
