Slab bridges may be composed of single or multiple spans.
Concrete arch bridges may consist of either a single arch or multiple arches supported by abutments and intermediate piers.
A more recent type of bridge currently gaining popularity as a "signature" structure is the cable-stayed bridge with a cast-in-place, reinforced, or segmental deck.
A simple beam bridge is commonly used for moderate spans. Variations of the precast I-girder include the PCI bulb-tee or bulb-tee sections developed by various states.
A box beam bridge is supported by abutments and piers in the same way as a simple- or continuous beam bridge.
Segmental bridges are popular when the construction site is restricted. They can be cast-in-place or precast, and can employ span-by-span or balanced cantilever construction.
