Historic Covered Bridges In New York StateNew York State is home to one of the longest single span covered bridges in the world. This is the old Blenheim Bridge over the Schoharie Creek at North Blenheim built in 1855 (located 23 miles from Cobleskill, NY). There are many other covered bridges in New York State and all are on the National Historic Register.
The earliest known covered bridge built was in 1825 and the last to be built was in 1912. Timber and stone were abundant in New York State and were great inexpensive materials for the use in building the covered bridges. Actually the first wooden bridges were not covered and had a short lifespan due to weathering. It was found that covering the wooden bridges increased their lifespan from about 9 years to more than 80 years.
