This list of the longest arch bridge spans ranks the world's by the length of their main. The length of the main span is the most common way to rank bridges as it usually correlates with the engineering complexity involved in designing and constructing the bridge. If one bridge has a longer span than another it does not necessarily mean that the bridge is longer from shore to shore or from to ab. An arch bridge is a with at each end shaped as a curved. Arch bridges work by transferring the weight of the bridge and its partially into a horizontal thrust restrained by the abutments at either side, and partially into a vertical load on the arch supports. A (a long bridge) may be made from a series of arches, although other more economical structures are typically used today.
