Commuters could soon bounce to work on the world's biggest open air trampoline.
The bizarre project has the backing of London mayor Boris Johnson and could be partially funded by council taxpayers.
An artist's impression shows a giant trampoline close to the London Eye on the South Bank.
The project has been conceived by a charity, Architecture for Humanity and is backed by Transport for London.
The Bounceaway is one of several ideas adopted by Boris Johnson's £1.8m Future Streets Incubator scheme to test new ideas of open spaces.
Architecture for Humanity's Beth Worth said the designers were inspired by a 170-foot long trampoline created for a Russian arts festival.
