In October of last year street artist Megx converted a bridge in Wuppertal, Germany into a giant Lego structure using colored panels that create the illusion of being the underside of Lego bricks. The bridge itself is part of the Wuppertal Bewegung e.V., an old train line that has been converted to a pedestrian and cycle path. How great is this? There’s been no shortage of giant toys and games in the streets lately. See much more on his website. Photos above courtesy Lukas Power and Rolf Dellenbusch.

Megx's website is fun, too.
