Which type of bridge is known for its ability to span greater distances than a simple beam bridge?

The ability of a bridge to span greater distances than a simple beam bridge is primarily associated with suspension bridges. Suspension bridges utilize cables suspended between towers to hold up the bridge deck, which allows them to cover long distances without the need for extensive intermediate supports. This design enables suspension bridges to effectively distribute loads through the cables, resulting in less material usage and a lighter structure compared to other bridge types.

Cantilevered bridges do allow for significant spans and can extend further than simple beam bridges, but not to the extent of suspension bridges. Arch bridges also provide excellent strength and can span considerable distances, but their design is generally more limited in the total span compared to suspension bridges. Truss bridges are efficient and can span substantial distances as well; however, they are usually designed for specific load conditions and are not optimized for the longest spans like suspension bridges.

Thus, while cantilevered, arch, and truss bridges have their own advantages, the characteristic that allows for the greatest spans over water bodies or valleys distinctly belongs to suspension bridges.
