The cable car would cross the water at a height of around 50 metres, similar to that of The 02, and would take around five minutes to travel from one side to the other.
It would be the UK’s first urban cable car and could carry up to 2,500 passengers an hour in each direction – the equivalent of 50 busloads.
The scheme is one of a number of alternative initiatives being considered, following opposition to a six-lane road bridge linking the two points.
It will be privately funded and carry cyclists as well as pedestrians. TfL is currently in talks with potential operators.
"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," said London Mayor Boris Johnson.
