The Rolling Bridge is an award winning design by Thomas Heatherwick that uses hydrolics to retract and extend similar to the way a Rollie Pollie curls and uncurls. Completely retracted it takes the shape of an octagon. It’s an interesting design, but I sure hope they speed up the uncurling process. It retracts and extends at such a snail’s pace, it should have been called The Slow Rolling Bridge.
