Stone Arch Bridge over McCormick's Creek in Indiana. Listed on the National Register of Historic Places.

An arch bridge is a bridge with abutments at each end shaped as a curved arch. Arch bridges work by transferring the weight of the bridge and its loads partially into a horizontal thrust held by the abutments at either side. A viaduct (long bridge) may be made from a long arcade of arches. However other less expensive structures are typically used today.
