Phase two of London's cycle "Quietways" scheme has been announced, extending segregated cycle lanes and junction changes to all 32 boroughs.
Phase one comprises seven routes in 15 boroughs, the first of which are due to open in spring 2015.
Phase two will re-shape roads and junctions in Ealing and Twickenham town centres and other major thoroughfares.
A "significant number" of the new projects should be under way by 2016, the mayor's office said.
'60s relics'
Other proposals in phase two include a segregated cycle route along part of the A316 and improvements to the existing Cycle Superhighway 9 (CS9) in Hammersmith & Fulham and Hounslow.
New cycle crossings are due to be installed on the A406 North Circular Road at Neasden and near Ilford, while Abbey Wood station will get a new cycle "superhub" and improved links to Thamesmead.
