Durham’s got something only Forth Worth, Texas, has: an arch-supported, stress-ribbon pedestrian bridge. If you walk down the American Tobacco Trail or drive down Interstate-40 through Durham, you’ll see the $11 million bridge – a work of steel art, consisting of a large metal arch of rolled steel that bows over I-40 with no support in the center. The walking deck is only 12 inches thick and is made of concrete and reinforced steel. This bridge is being touted as the second of its kind in the country, and it opened for public use last Thursday. The bridge completes the trail’s missing link between Chatham and Durham counties. The American Tobacco Trail is a 22-mile long rail-to-trail conversion that runs on the former Norfolk & Southern railroad corridor route and crosses through Durham, Chatham and Wake counties.
