London’s colorful and controversial mayor Boris Johnson has endorsed a new scheme to attack the city’s transport mess with sky high bike lanes connecting the City of London with east London. The proposed SkyCycle project won’t be free though, access fees are planned to be £1 per ride. Still, it seems to be an eminently practical way to challenge congestion. The first bike lane in the sky should be in place by 2015, if the funding gets approved.
