A dull bridge in the industrial city of Wuppertal in Germany has been turned into a tribute to everyone’s favourite childhood toy. And for once, the occasional German weakness for bright clashing colours (e.g. the VW Polo Harlequin), has found a productive outlet. The bridge in question had been converted from a disused railway to become a walking path, but the ugly concrete was not really in keeping with the spirit of a nice Sunday afternoon stroll.
