High-speed rail project promoter HS2 Ltd has decided to construct a 9km tunnel between Old Oak Common and Northolt, instead of a surface route as previously planned.
HS2 Ltd investigated the advantages of building a tunnel following a suggestion from residents of Ealing Council. It concluded that a tunnel would cut 15 months from construction time, cause less traffic disruption and potentially save money.
A total of 18 road bridges would have needed to be demolished under previously plans, including the Hanger Lane gyratory which connects the A40 and the A406 North Circular.
“The study we commissioned found that for this specific station of the line, the cost of tunnel would be comparable with a route on the surface without the need to replace bridges and divert associated utilities,” said HS2 Ltd’s London community and stakeholder manager Peter Fry.
“The proposed tunnel will be included as the preferred option in the draft environmental statement for the first phase of HS2, so the community and stakeholders will have the opportunity to respond to this proposal as part of the consultation in coming months.”
