Cody Dock Rolling Bridge

About

The Cody Dock Rolling Bridge is a moveable pedestrian bridge in London, England at Cody Dock. The bridge is manually rolled using winches to alternate between pedestrian and boat traffic. It crosses a channel that runs from River Lea to a nearby dock.

It was designed by Thomas Randall-Page and Tim Lucas, and built by Cake Industries. The concept for a rectangular rolling frame came from an article titled Roads and Wheels by mathematicians Leon Hall and Stan Wagon and an interactive exhibit of square-wheeled tricycles at the MoMath museum.
