A '''truss arch''' may contain all horizontal forces within the arch itself, or alternatively may be either a thrust arch consisting of a truss, or of two arcuate sections pinned at the apex. The latter form is common when the bridge is constructed as [[cantilever]] segments from each side as in the [[Navajo Bridge]].
