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 restrained by the abutments at either side. A viaduct (a long bridge) may be made from a series of arches. The Varda Viaduct, aka Giaour Dere Viaduct, is a railway viaduct situated at Hacikiri (Kiralan) village in Karaisali district of Adana Province in southern Turkey. Taurus mountains.
