There are several types of bridges, each with its own advantages and disadvantages. The main types of bridges are:
- Arch Bridge
- Beam Bridge
- Cantilever Bridge
- Suspension Bridge
- Cable-Stayed Bridge
- Tied-Arch Bridge
- Truss Bridge
Arch bridges use one or more arches as the main structural component, with the arches positioned beneath the deck. Beam bridges are the simplest type of bridge, consisting of a crossbeam long enough to cover the span, and support from abutments under each end. Cantilever bridges are built using cantilevers, which are horizontal beams supported on only one end. Suspension bridges are bridges where the roadway, or deck, is suspended by cables. Cable-stayed bridges are similar to suspension bridges, but the deck is supported by cables attached to towers. Tied-arch bridges combine features from beam bridges and suspension bridges. Truss bridges are the strongest type of bridge, consisting of a structure whose parts are put together to form triangles.
