Who invented bridge?

Answer 1

The name of the first person to build a bridge is not recorded by history.

Answer 2

When someone says the word bridge, you think of the famous bridges, like London Bridge, Brooklyn Bridge, Golden Gate Bridge. Right? But a bridge by definition is a structure that provides passage over a river, road, or basically any gap. So these (relatively) new bridges that we know are just advances over old ones. Of course, bridges can be really small, and easy to make. It is also a simple concept, so has been around for thousands of years. Nobody was credited with inventing the bridge. Think about it this way - asking who invented bridges is similar to asking who invented boats - of course someone invented the motor, and parts of new boats but a boat is really anything that is designed to provide transportation in water. That would have been done a long time ago - all someone need to do is jump in a barrel and the're ready to go! Same with a bridge. Stick a plank of wood over a stream and you've made a bridge.
