Cathedral arch : ウィキペディア英語版 | Cathedral arch
A cathedral arch is an arched structural system where 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. The largest cathedral arch bridge in the world is the Galena Creek Bridge near Reno, Nevada.〔 == References ==
