The Dingleton Hill Covered Bridge, also known as the Cornish Mills Bridge, is a historic wooden covered bridge, carrying Root Hill Road over Mill Brook in Cornish Mills, New Hampshire. The multiple Kingspost truss bridge was built in 1882 by James Tasker. It has a single span 79ft long, resting on an original stone abutment and a 1954 concrete abutment. Its original wood-shingle roof has been replaced by corrugated metal. Only the lower half of the trusses are sheathed with vertical planking; the upper half is exposed.
