FOI - Cycle lanes and Cycle Super Highways

The Mayor, Sadiq Khan, has mentioned on several occasions recently that he has “built 140km” of cycle lanes since he came to office. The Mayor’s press office has also started to use this figure in responses to media.

Please can you list each of these newly-built lanes, the start and end point of each lane (eg street junction) and the length of each lane.

Please can you indicate when work started on each cycle lane, when it was completed, how much the work cost and which organisation provided funding.

Please include cycle superhighways in the generic description of cycle lanes.

Please advise whether a lane is measured as being twice its basic length (ie, to account for cyclists travelling in different directions).
