concrete arch
Solid curved span
A concrete arch is a curved structural element made of concrete, designed to span an opening while transferring weight outward and downward to its supports.
Concrete arches appear in bridges, dams, and buildings, prized for their strength and ability to cover long spans without intermediate supports: The concrete arch bridge crosses the gorge in a single sweep.
