The new 15-mile route unveiled by the Mayor will include Dutch-style fully segregated cycle tracks along, among other places, the Victoria embankment and the Westway flyover.
Under the plan, a range of new cycle routes will open over the next four years parallel to and named after Tube lines and bus routes.
The plans will include a new network of “Quietways” – direct, continuous, fully signposted routes on peaceful side streets, running far into the suburbs, and aimed at people put off by cycling in traffic.
It will also include improvements to junctions deemed the least safe fo cyclists, including Blackfriars, Vauxhall and Elephant & Castle and it will enforce 20mph speed limits for all traffic on some cycle routes.
An electric bike hire scheme, similar to the existing Barclays Cycle Hire, will also be trialled.
“We want to give Londoners the road transport network to make cycling attractive to large numbers of people,” Boris Johnson said.
