London Mayor Boris Johnson has given his support to proposals for a cable car that would cross the the Thames between North Greenwich and the Royal Victoria Docks.
The £25m scheme would be privately funded and would involve construction of cable car stations near to North Greenwich tube on the south side of the river and Royal Victoria DLR on the north.
The cable car would be suspended 50 metres in the air and capable of carrying 2,500 passengers (including cyclists) each hour.
If a private sector partner can be found in time, it would provide a direct link between the O2 Arena on the Greenwich Peninsula and the ExCel centre by the Royal Victoria Docks, in time for 2012. Both venues will stage events at the London Olympics.
Johnson said: "A cable car spanning the majestic Thames would not only provide a unique and pioneering addition to London's skyline, but also offer a serene and joyful journey across the river.
“Passengers would be able to drink in the truly spectacular views of the Olympic Park and iconic London landmarks whilst shaving valuable minutes from their travelling time. It would also provide a much needed enhancement of cross river options to the east of the city."
Previously, Transport for London had discounted plans for a cable car crossing between North Greenwich and Canary Wharf.
