An arch bridge is a bridge whose main load-carrying element is an arch, a curved structure carrying load primarily in compression, and among the oldest bridge forms.

Arch dam

An arch dam is a concrete dam curved in plan so water pressure is carried as arch thrust into the canyon walls, using far less concrete than a gravity dam.

Arch-gravity dam

An arch-gravity dam is a curved concrete dam that resists water partly by arch action into the valley walls and partly by its own weight.

Archbasilica of Saint John Lateran
