Contoocook Railroad Bridge and Depot
Built in 1889 on the granite abutments of an older span, this is the world's oldest
surviving covered railroad bridge. 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 until after 1900, longer than any other major
railroad. The nearby depot was built in 1850 on the earlier Concord & Claremont
Railroad, which was acquired by the Boston & Maine in 1887.
