From Heatherwick Studio web site:”The studio was commissioned to design a pedestrian bridge to span an inlet of the Grand Union Canal at Paddington Basin, London, and provide an access route for workers and residents. Crucially, the bridge needed to open to allow access for the boat moored in the inlet.
The aim was to make the movement the extraordinary aspect of the bridge. A common approach to designing opening bridges is to have a single rigid element that fractures and lifts out of the way. Rolling Bridge opens by slowly and smoothly curling until it transforms from a conventional, straight bridge, into a circular sculpture which sits on the bank of the canal.
The structure opens using a series of hydraulic rams integrated into the balustrade. As it curls, each of its eight segments simultaneously lifts, causing it to roll until the two ends touch and form a circle. The bridge can be stopped at any point along its journey.
The whole structure was constructed at Littlehampton Welding on the Sussex coast and then floated up the Grand Union Canal, before being lifted into position and attached to the hydraulic system which powers its movement.
The Rolling Bridge won a number of awards including a Structural Steel Award, and an Emerging Architecture Award.
It opens every Friday at midday.”
