3. The Rolling Bridge: A Footpath That Curls Into an Octagon
At London’s Paddington Basin, a short footbridge has a transformation that seems better suited to a folding toy. When extended, the Rolling Bridge provides a straight route across a canal inlet. When it opens, its connected sections curl upward until the bridge forms a compact, eight-sided shape on the bank.
The design comes from Heatherwick Studio, and the trick lies in its eight linked sections. A hydraulic system changes their positions together, gathering the walkway into a sculpture rather than simply lifting one end into the air. The bridge measures only about 12 meters long, so its appeal comes from movement rather than monumental scale.
The photograph shows both arrangements, which is useful because the curled version does not immediately look like something you could walk across. That is the pleasure of the design: the same pieces make two convincing objects. In one position it is useful pavement; in the other, it looks like an oversized metal bracelet beside the water.
