The North-South Cycle Superhighway is already under construction between Stonecutter Street and Elephant & Castle.
TfL, together with Camden and Islington Councils, is now consulting on proposals to extend it north up to King’s Cross.
The proposal is that it should continue north on Farringdon Road to Greville Street where northbound cyclists would turn onto a quiet back-street route to King’s Cross.
Southbound cyclists from King’s Cross would turn off the back-street route onto Farringdon Road at Ray Street via a new signalised junction and continue south on a stepped cycle track. Detailed proposals
