Old Blenheim Bridge is a covered wooden bridge that spans Schoharie Creek in North Blenheim, NY. At 232 feet long, it is the longest single span wooden covered bridge in the world. The bridge is also one of the oldest of its type in the United States.
A report of Historic American Engineering Record suggests that the Bridgeport bridge has clear span of 210 feet on one side and 208 feet on the other, while Blenheim was measured to have 210 feet in the middle in HABS drawings from 1936. In August 2003, new measures taken of Blenheim abutments were 209 feet 2 inches on upstream side and 205 feet 6 inches on the downstream side.
