This summer, two historic milestones were reached on the HS2 project in the United Kingdom: 🌉 The Colne Valley Viaduct – 3.4 km of graceful curve above lakes and valleys, already a symbol of collective ingenuity thanks to the launching girder “Dominique” and the precise placement of more than 1,000 unique precast segments. 🚇 The Chiltern Tunnel – 16 km excavated by Florence and Cecilia, the two giant TBMs, delivering the longest tunnel on the line. Two complementary structures, two challenges met: one soaring through the air, the other carved underground. Together, they embody our ability to build, to innovate and contribute to sustainable, low-carbon mobility. 👏 Congratulations to all the teams of Bouygues Travaux Publics, Align JV and our partners for these achievements that made this summer truly exceptional and mark a key stage in the HS2 adventure. #HS2 #BuildingForLife #SustainableMobility HS2 (High Speed Two) Ltd Align JV Sir Robert McAlpine VolkerFitzpatrick Ltd
