highway bridges
Elevated roadway crossings
Highway bridges are structures carrying roads over obstacles—rivers, valleys, other roads, or railways.
The term distinguishes them from pedestrian bridges, railroad bridges, or aqueducts.
Highway bridges range from simple overpasses to major spans like suspension or cable-stayed bridges: The state allocated funds to repair aging highway bridges.
