The Jediah Hill Covered Bridge is also known as the Groff Mill Bridge. Jediah Hill Bridge spans the West Fork of Hill Creek and is one of several sources that supplies water for Hill Creek Lake at Winton Woods, a recreational area. The creek bed at the bridge site is 40 feet wide.
Built in 1850, the Jediah Hill Bridge has been refurbished around the late 1970's. It was dismantled, new stone abutements were built and the bridge was reconstructed. Thee plank siding and a shake roof were added. The interior has horizontal floor planking and a queenpost truss with an "X" support in the center panel. Today, 2020, the roof is full of holes and needs to be replaced.
Listed on the National Register of Historic Places, Jediah Hill Bridge is the only covered bridge left in Hamilton County, Ohio.
