New Henniker Bridge or New Bridge was a covered bridge in West Hopkinton, New Hampshire, which carried Henniker Road over the Contoocook River. The truss bridge was completed in 1863, and was the second bridge on the site. The original stone arch bridge was built in 1845 and was washed away by flood in 1852. The bridge was just over 20 feet (6.1 m) wide and 180 feet (55 m) long, and consisted of a single span supported by two triple lattice trusses resting on granite abutments. The patent drawings show an all-timber truss with fixed intersection angles in the center of the span. At the ends of the span the angles of the diagonals vary. The end post is vertical, and each brace further from it is sloped a little more.[1][2]
