Contoocook Railroad Bridge and Depot

Built in 1889 on the granite abutments of an older span, the Contoocook Railroad Bridge 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 the Boston & Maine acquired in 1887.
