Mayor of London Boris Johnson says he ‘might well’ consider supporting the construction of a bridge across the Thames for pedestrians and cyclists linking Rotherhithe with Canary Wharf.

At Mayor’s Question Time on Wednesday, Lib Dem London Assembly member Caroline Pidgeon revealed that transport charity Sustrans is to launch a competition for designs for a new bridge.

Ms Pidgeon said that a new bridge could help relieve overcrowding on the Jubilee line.

The Mayor replied: “Please tell [Sustrans] to come in as soon as possible and we’ll have a look at it … I do agree there should be a crossing in that area. Let’s see what they’re proposing.”

Tbe Mayor joked that a catapult across the Thames could be one option.
