It has carried traffic for over a century, and the nomination cites engineering, commerce and transportation as areas of significance.","narrative":"Just west of New Concord, Ohio, U.S. Route 40 crosses Fox Creek on an S-shaped stone bridge built in 1828 as part of the National Road. The structure is about 140 feet long and 26 feet wide, with a single 30-foot arch over the creek. The roadway curves slightly less than 20 degrees south at the east end and slightly less than 22 degrees north at the west end. Walls and vault are cut stone laid in courses, and the floor is brick. The S shape had practical purposes: it avoided sharp approach curves, shortened the arch needed, avoided steep grades and protected the back fill from erosion. Because the road meets the stream at an angle, a straight crossing would have cost more. The bridge is one of five original National Road S bridges remaining in eastern Ohio. In 1936 the Ohio chapter of the Daughters of the American Revolution persuaded the highway department to build around such bridges rather than replace them. It remains passable without load limits.","period_of_significance":"1828 (19th Century)","architect_builder":null,"architectural_style":null,"criteria":[],"status_note":"Listed in excellent condition; altered only by a brick floor and some repointing.
