Hillsborough Railroad Bridge

The Hillsborough Railroad Bridge was a historic covered railroad bridge spanning the Contoocook River in Hillsborough, New Hampshire. It was destroyed by arson in 1985. The bridge was a two-span Town-Pratt lattice truss span, mounted on granite abutments and a central wooden pier, which replaced a granite pier washed away in 1938. It had a total length of 219 feet (67 m). It was built in 1903 by the Boston and Maine Railroad, and was at least the second bridge on the site.

The bridge was listed on the National Register of Historic Places in 1975. At the time of its nomination it was one of six covered railroad bridges in the state; it and at least one other (the Goffstown Covered Railroad Bridge) were destroyed by the actions of arsonists.
