Bridges
Suspension bridges are built to make use of tension, whereas most other types of bridges make use of compression to bear their load. Suspension bridges are usually designed with the deck suspended below a series of towers by cables. Other types of bridges are generally either designed with the deck being supported from below by pillars, or made up of an arch.
civil engineers, structural engineers, and architects are the main bridge builders.

We can reasonably infer that the first bridges were logs, thrown across narrow streams.
