A cable-stayed bridge is a bridge that consists of one or more pillars, with cables supporting the roadbed. There are two major classes of cable-stayed bridges, differentiated by how the cables are connected to the pillars. In a parallel attachment design, the cables are made nearly parallel by having the height of attachment on the pillar be similar to the distance from the pillar along the roadway. In a radial attachment design, the cables all connect to or pass over the top of the pillar.

The cable-stay design occupies a sweet spot of length between cantilever bridges and suspension bridges. Within this sweet spot a suspension bridge would require more cable, while a full cantilever bridge would require considerably more material.
