I took these photos of Boner Bridge last Sunday. Boner Bridge, built in 1869, crosses the Little Pigeon Creek on the Warrick/Spencer county line in Southern Indiana.
Boner Bridge is thought to be one of only five of its kind in the United States. The 260 foot, one-lane, iron bow, string-trussed bridge has sandstone abutments, iron bents and a wood plank floor. It is unique because it is known as a three-span bridge as it contains three arches. The two arches on both ends of the bridge measure 50 feet in length. The middle arch is the bridge's longest, measuring 160 feet.
