Work to excavate four new customer passageways at Kennington Tube station as part of the Northern Line Extension (NLE) project has been completed allowing full reopening of the station.
Northern line passengers have been unable to interchange between the Bank and Charing Cross branches at the station since the end of May when the work got underway.
Transport for London has said that the Ferrovial Laing O’Rourke joint venture working on NLE has excavated almost 2,000t of London Clay by hand. The work also included installation of new timber and steel supports, 9,000t of concrete and 500 tunnel rings for the passageways.
Flooring, tiling and electrical works are still to be completed but these tasks will be undertaken during engineering hours.
The new passageways will make it quicker and easier for customers to change between different branches of the Northern line at Kennington and will be essential for those using the new NLE from Kennington to Battersea Power Station via Nine Elms, which is targeted for completion in 2020.
The new running tunnels for NLE were connected to the existing tunnels over Christmas last year and track is currently being laid.
TfL director of major projects Stuart Harvey said: “The Northern Line Extension is an essential part of our investment programme which will continue to improve customers’ journeys and add vital new capacity to the capital’s transport network.”
