Built in 1889, the Contoocook Railroad Covered Bridge is the oldest surviving covered railroad bridge left in the United States. It was probably designed by Boston & Maine Railroad engineer Jonathan Parker Snow )1848-1933) and built by carpenter David Hazelton (1832-1908). Under Snow, the Boston & Maine utilized wooden bridges on its branch lines longer than any other major railroad.
