The longest bridges in the world are viaducts or trestle bridges. It is easier to design a high, elevated roadway by directly supporting it with many towers or piers (as in a viaduct or trestle bridges). It is more difficult to design an elevated roadway with a large unobstructed span (as in a suspension bridge or arch bridge). However, the bridges with the longest unobstructed spans in the world are invariably suspension bridges, because ...
There are many different lengths of suspension bridges.
In simple terms, cable stayed use less cables then a suspension bridge. They are a combination of both beam and suspension.

We're not sure about their discovery, but the absence of suspension bridges was discovered in 1492, when Columbus, attempting to walk from Portugal to India, realized he couldn't. Engineers such as Roebling and Eiffel, many years later, discovered steel. And cheese. Suspension bridges were thus implied, if not actually observed.
