Site update

National Grid continues to make good progress with works at its New Cross site. Since preparation began at the site in June 2019, a deep vertical shaft has been constructed to access the tunnel below, and two tunnel boring machines have been launched from here. We have another busy year of works planned for 2022, which will see these tunnel boring machines continue to work their way from the site, burrowing eastwards towards our sites in Kidbrooke and Eltham, and westward towards our sites in Lambeth and Clapham.
