Update- August 28, 2011: Old Blenheim Bridge was a wooden covered bridge that spanned Schoharie Creek in North Blenheim, New York. With an open span of 210 feet (64 m), it had the longest span of any covered bridge in the world; although the structure’s total length of 232 feet (71 m), made it second in that respect to the Bridgeport Covered Bridge (233 feet (71 m) long with a 210 feet (64 m) span). The bridge, opened in 1855, was also one of the oldest of its type in the United States. It was destroyed on August 28, 2011 as a result of flooding from Tropical Storm Irene.
