London once built a pedestrian bridge that twisted like a corkscrew to clear the canal for boats; the unusual crossing was later removed in 2013

The Helix Bridge, a marvel of engineering with its twisting and retracting design, became an iconic visual landmark connecting Paddington Basin. However, the intricate mechanisms posed operational issues, leading to its decommissioning by 2013. As urban demands evolved, authorities opted for a more straightforward pedestrian structure, shedding light on the persistent obstacles faced by innovative designs in today's urban landscapes.
