Recent travelers on east London's Leaway footpath may have seen a bridge with iconic, vertical square hoops roll over onto its side and then upside down as they waited to cross the ex-industrial Cody Dock. The inversion, however, need not have caused any worry, as the bridge - the first of its kind - rolls to raise the height of its deck for boats underneath. The installation of the Cody Dock Rolling Bridge in August 2022 concluded an eight-year design journey involving a playful idea, strict tolerances, and some tricky math. "It's kind of one of those mad ideas that's actually come to fruition," says David Knight, CEng, MICE, MIStructE, the design director of London-based Cake Industries. |
