Swing bridge

A swing bridge is a bridge that has its primary structural support at or near to its center, about which it can then pivot horizontally.

In its closed position, a swing bridge carrying a road over a river or canal, for example, allows road traffic to cross. When a water vessel needs to pass the bridge, road traffic is stopped (usually by traffic signals and barriers), and then motors rotate the bridge approximately 90 degrees horizontally about its pivot point.
