Opening of the new entrance to Bond Street tube station on the north side of Oxford Street marks completion of a major programme of ground engineering work.
Work on the £300M upgrade has spanned more than five years and involved significant piling, compensation grouting, underpinning and mechanically and hand excavated tunnelling work.
The new entrance and 350m of additional passage tunnels provides step-free access and a 30% increase in capacity.
The project was delivered by Costain Laing O’Rourke with ground engineering and foundation work undertaken by Bachy Soletanche.
London Underground managing director Mark Wild said: “The new, modernised Bond Street station will make journeys quicker and easier for the hundreds of thousands of people who travel through it every day.
“It’s fantastic to open the station in time for the Christmas shopping period, making Oxford Street more accessible to all of our customers as well as boosting businesses in the area. The expansion of the station is another step in the investment we are making in Oxford Street and the surrounding area.”
