Cork Plain Bridge

This Contoocook River crossing was established by the Second New Hampshire Turnpike Corporation, chartered in 1799 to build a toll highway sixty miles from Amherst to Claremont.Opened in 1801 and made free in 1837, the turnpike joined rich Connecticut River Valley farms with Massachusetts markets. Named for the wide plain to the south, a steel Warren Truss bridge of late 19th or early 20th century design stood here until 2009.
