Dean Road Bridge

Why it's listed
Dean Road Bridge carries a lightly traveled township road over the Vermilion River in a wooded, largely unspoiled area west of South Amherst, Ohio. Built in 1898 by the Massillon Bridge Company, it is a double intersection Pratt box truss with a clear span of 171 feet, a wood strip deck and a metal structure, probably rolled iron. The bridge is level, but its roadway slopes downward to the north, because the south abutment sits on a fifty-foot shale cliff while the north bank lies in the flood plain. This inclined roadway is a rare feature. The bridge is the only box truss of its type remaining in Lorain County. Its parts were made at the factory and assembled quickly on site, giving local governments an inexpensive, sturdy structure. Repairs have replaced road sections and strengthened the abutments. Rust and missing elements remain, but the bridge is open to traffic and still connects the two ends of the road.
Significance in brief: The nomination calls it an excellent example of turn-of-the-century metal truss bridges and the only box truss bridge of its type left in Lorain County. Its inclined roadway is a unique feature. Its craftsmanship, ornamentation and largely natural setting add to its distinction, and it represents the Massillon Bridge Company's prefabricated truss technology.

What listing means for this property
For a publicly owned building or structure, listing mainly matters when federal funds, permits or licences are involved: projects then go through Section 106 review so effects on the property are considered. Listing also strengthens applications for preservation grants and, for leased income-producing uses, can enable the federal rehabilitation tax credit.
