Old Enon Road Stone Arch Culvert
Also known as: Rocky Point Stone Arch Culvert; Odot Sfn 1253670; Stone Arch Culvert over Muddy Run on Enron Rd.
Why it's listed
Spanning the rocky gorge of Mud Run at Rocky Point, this stone arch culvert carries Rocky Point Road, part of the old Enon Road, in Mad River Township, Clark County. Samuel S. Taylor built it in 1871 under a county contract of $450 plus the old wooden bridge it replaced. The structure is about 20 feet wide, 24 feet long and 16 feet high, with a barrel vault 12 feet wide. It is made of locally quarried dolomitic limestone, laid in mortar in well-formed courses, and rests directly on bedrock. Later changes include steel deck sections and guardrails added by 1972, concrete patching, and fill of reused architectural stone at the approaches. A 2006 engineering inspection found the masonry arch generally in good condition. The culvert is considered important as a rare surviving example of a once-common Ohio road structure. It is the oldest structure in the county's bridge inventory and its only remaining stone culvert.
Significance in brief: The nomination argues the culvert is a fine and rare example of a mid-sized single-span barrel-vaulted stone arch culvert, a type once common on Ohio roads. It is the oldest structure in the county's inventory of 241 active bridges and culverts and the only remaining stone culvert there. It also retains sound original stonework and good historical integrity despite later alterations.
