Dingleton Hill Bridge #22
Root Hill Road
The Dingleton Hill bridge was built by James Tasker, who is known to have built at least eleven bridges in the area. It was assembled in a schoolyard and then transported to the site. The farmers who used it would occasionally repair it. Milton Graton restored it in the summer of 1983 at which time he repaired the stone abutments and roof, leveled the bridge and installed new bearing shoes and plank flooring.
