HS2 is a new high-speed rail line that will be the backbone of the UK’s rail network. Phase One of this project will connect London to Birmingham by between 2029-2033. In July 2017 the Align joint venture was awarded the C1 package of HS2. Align is a joint venture of three international infrastructure companies; Bouygues Travaux Publics, Sir Robert McAlpine, and VolkerFitzpatrick. C1 consists of 21.6km (13.5mi) of high-speed rail infrastructure that includes a 3.5km (2.2mi) viaduct, 16km (10mi) twin-bored tunnel and five vent shafts accommodating both intervention and tunnel ventilation facilities.
