TfL has unveiled a series of measures lately to encourage more people to make journeys on either foot or by bike.
Among the initiatives is an updated tube map, which shows the distance between stations by the time it would take to walk them.
The idea, presumably, is to bring home how quick most short tube journeys would take by walking.
The problem for Rotherhithe locals? The estimated distance between Canada Water station and Canary Wharf is a whopping 144 minutes.
This would’ve been cut down if a walking and cycling bridge or even a ferry had gone ahead.
Both have been shelved. Is it any wonder council officials have called this deeply frustrating?
