Dingleton Hill Covered Bridge, Wooden covered bridge in Cornish Mills, New Hampshire.

Dingleton Hill Covered Bridge is a single-span King post truss structure 79 feet long, carrying Root Hill Road over Mill Brook. Only the lower half of its trusses is sheathed in vertical planking, leaving the upper half exposed, and the portals are finished in vertical board siding. It rests on an original stone abutment and a 1954 concrete abutment, with a corrugated metal roof replacing the original wood shingles.

James Tasker, a local builder, constructed the bridge in 1882 for $812. Milton Graton restored it in 1983, and a rededication ceremony was attended by one of Tasker's descendants. In 2016 a school bus that was overweight and overheight crossed the bridge and damaged it; repairs allowed it to reopen several months later.

A sign at the junction of Town House Road, Dingleton Hill Road and Root Hill Road marks the span as Covered Bridge No. 22. The bridge is also known as the Cornish Mills Bridge, after the village of Cornish Mills it serves.

The bridge still carries road traffic on Root Hill Road today. Visitors can walk across to view the interior construction up close and see how the wooden frame supports the span.
