It is one of only six existing bridges known as double-barreled covered bridges, because a wall separates the two lanes. Blenheim's covered bridge was listed on the National Register of Historic Places in 1965. It is one of 24 historic covered bridges in New York. The Blenheim covered bridge was taken out of service in 1931, when the steel truss bridge was built. The covered bridge and the surrounding area have been maintained as a park.
People can walk on the covered bridge, but the western end of the bridge no longer reaches the bank.
In 1930, the iron extension cracked beneath a heavy load of ice and the bridge was abandoned in favor of the new steel truss bridge. In 1932 the iron extension was removed, leaving the end of the bridge in mid-air. Fuller said the state's offer to structurally repair the covered bridge is pointless because the bridge suffered extensive damage during the January 1996 flooding.
