At one time, New York State had over 300 covered bridges, but over the years, floods, fires, and modernization have claimed all but 32 of them. Both the Hyde Hall Covered Bridge and the Old Blenheim Bridge are proud record holders. Located in Glimmerglass State Park, the Hyde Hall Covered Bridge is the oldest existing covered bridge in the United States. The Old Blenheim Bridge was the longest single-span covered bridge in the world until it was washed away by Tropical Storm Irene in 2011 when the Schoharie Creek flooded. Today, Oxford, New York, is home to the Theodore Burr Covered Bridge Resource Center, which was specifically designed for covered bridge researchers�the first-ever center of its kind.
