London could soon have subterranean ringroad

Central London could be set for a brand new ringroad, only this one will be underground, reports.

Mayor Boris Johnson has outlined ambitious plans to create a 22-mile underground dual carriageway ringroad. Running between Islington, the Westway, Battersea and Wapping, the road could provide London with cleaner air, cut journey times and ease traffic around known pinch points, such as the Earl’s Court one-way system.

Not only that, residents on the South Circular will also be given relief, whilst Tower Bridge will be closed to all traffic except buses and cycles.

Set to be named the Inner Orbital Tunnel, the ringroad would link the A40, A12, A1 and A2.

It is hoped the scheme would future-proof London’s roads, which are expected to become strained under continued population growth. Recent forecasts suggested that, if nothing were to be done, the central zone would see a 60 per cent rise in congestion by 2031, whilst the totals would rise by 15 to 25 per cent in the outer areas.

Commenting on the proposals, deputy mayor for transport, Isabel Dedring, told “We are at the very early stage in exploring the potential.

“Cities such as Paris, Oslo and Boston have undertaken these kinds of ambitious projects and have seen dramatic results. This is not about creating a motorway through the centre of London. It’s about freeing up capacity on the city surface, improving air quality and reclaiming space for public parks, pedestrians and cyclists.”
