World's Strangest Bridges
Rolling Bridge: London
Architecture firm Heatherwick studio rose to the challenge of designing a bridge to span the narrow Grand Union Canal at London’s Paddington Basin—while still allowing ships free passage. The strange, ingenious bridge is made of eight identical segments capable of rolling and unrolling like a party noisemaker. Every Friday at midday the hydraulic-powered construction is activated (regardless of boat traffic) to the amusement of waiting pedestrians.
