Islington Council are set to fight Boris Johnson’s £30billion plan to build a 22-mile underground motorway running through the borough.

The scheme, which will cost double that of the Crossrail project, would see a major junction built at Highbury Corner to join the A1 while creating links with Camden and Whitechapel.

When the motorway was announced as part of the GLA’s Infrastructure Plan 2050, the Mayor said it would remove “tens of thousands of cars” from London’s roads and help reduce the huge pollution problem in the city.

But a motion set to be read at full council next Thursday by the town hall’s environment and transport chief Cllr Claudia Webbe brands the scheme “damaging” and “inappropriate”.

It states: “The proposed scheme would be extremely damaging to Islington and is an entirely inappropriate method of addressing the long-term transport infrastructure challenges facing London.”

The council’s executive is set to put forward strong opposition to the underground motorway as part of the consultation on the infrastructure plan, which closes on Octber 31.
