A swing bridge (or swing span bridge) is a movable bridge that can be rotated horizontally around a vertical axis. It has as its primary structural support a vertical locating pin and support ring, usually at or near to its center of gravity, about which the swing span (turning span) can then pivot horizontally as shown in the animated illustration to the right.
The bridge rotates slowly laterally, allowing pedestrians to remain on the bridge while it is rotating. [1] The design includes a barrier on the western side to prevent entry, while, on the eastern side, pedestrians can step on and off the bridge while it is in motion. The speed of the bridge opening and closing is 0.15 m (0.16 yd) per second. [3]
