About HS2 South Portal & Colne Valley Viaduct School / College Visit

From here, our two tunnel boring machines Florence and Cecilia were launched to dig the Chiltern Tunnels, as well as the starting point of the Launching Girder called Dominique building the Colne Valley Viaduct. This is also the largest constraction site on HS2 with 550000 square meters of land.
