Cathedral arch
A cathedral arch is an arch used in bridge architecture. It consists of an arched structural system, wherein vertical load bearing occurs only at the crown, or peak of the arch. As applied to bridge design, cathedral arch bridges feature no intermediary spandrel column elements between the foundation abutments and the crown of the arch system, where the roadway superstructure is constrained to the substructure.
