London's Bridge is Folding Down, Folding Down....

 

British firm Knight Architects and structural engineers AKT II have completed a moving footbridge in Paddington, London, that opens and closes like the blades of a traditional hand-held fan.
Consisting of five steel beams that rise and fall using hydraulic jacks, Merchant Square footbridge by Knight Architects and AKT II spans a 20-metre width of the Grand Union Canal in Paddington Basin, close to Thomas Heatherwick's Rolling Bridge that curls into a ball.  Not much more to say about this one ;)....
