Quick Summary

An overpass is a bridge that carries one road, pedestrian path, or railroad over another at a different level. This design allows traffic on the lower level to pass underneath without interruption. The term "overcrossing" is a synonym for overpass.12

Overpasses are a type of bridge, and their construction often involves beam bridge engineering. For an overpass beam bridge, construction starts with concrete footings for supports and abutments. Steel beams, often manufactured off-site, are then placed and a concrete deck is cast on top to create a composite structure.3
