A suspension bridge is a bridge that has the road or track suspended between two very high pillars. The road or track is attached to the pillars by heavy wires.
Two main reasons for building a suspension bridge, instead of for instance a cheaper low bridge, are:
- It can span a very wide, deep rift.
- It can be built high over water to allow very tall ships to pass under it.
The largest suspension bridges in the world are:
One of the most famous suspension bridges is the Golden Gate Bridge (USA). One of the first is the Brooklyn Bridge.
