The Mayor of London has revealed further details of proposals for the city's road network.

Boris Johnson, who is in Boston as part of a trade mission to build economic and cultural ties with key cities in the United States, unveiled plans to redesign a number of road networks in the capital in order to unlock growth and make the capital a more attractive place to live and work.

The Mayor also visited the Central Artery-Tunnel Project, also known as the Big Dig, which is recognised as the largest and most complex highway project undertaken in the US. It replaced Boston's six-lane elevated Central Artery with an eight lane state-of-the-art underground highway.

The Mayor and TfL have considered more than 70 locations across the capital where the introduction of tunnels, fly-unders and decking could deliver benefits that are in line with the Mayor's 2050 Infrastructure Plan and the recommendations of the Roads Task Force.


Five locations have subsequently been identified as being suitable for further feasibility work by TfL:

• A mini tunnel at the A13 in Barking Riverside – By creating a new tunnel for the A13, a huge amount of land could potentially be opened up for future development whilst reconnecting the Borough of Barking with the new Barking Riverside development, which is the location for just under 11,000 new homes.

• Decking of the A3 in Tolworth – By decking over the A3, severance would be reduced and the area adjacent to the proposed Crossrail 2 station would be connected with the rest of the Borough, providing additional land for new homes.

• A fly-under at the A316 at Chalkers Corner – A small fly-under would reduce severance and radically improve facilities for cyclists and pedestrians and remove a major pinch point for traffic along the A316.

• A fly-under at the A4 in Hammersmith – By replacing the existing viaduct with a new tunnel, the town centre would be reconnected with the River Thames, creating new opportunities for development and open space.

• Decking or a mini-tunnel at the A406 in New Southgate – By building over this junction on the North Circular, land would be unlocked for new homes and connect the area around the proposed Crossrail 2 station.

Mr Johnson said: "Rebuilding some of our complex and aging road network underneath our city would not only provide additional capacity for traffic, but it would also unlock surface space and reduce the impact of noise and pollution.

"I am inspired by what the ambitious people of Boston have achieved here at the Big Dig, both in terms of reducing congestion and how they have dramatically improved the quality of life on the surface.

"In London we face similar challenges on our roads, but this could also be a fantastic opportunity to better shape our city and support economic growth."
