Pile driving has started on the U.K.’s longest railroad viaduct, which will be part of the London–Birmingham high speed rail system, known as HS2. The Coine Valley viaduct, northwest of London, is set to carry HS2 for 3.4 km.
The Align joint venture of Bouygues Travaux Publics, Sir Robert McAlpine and VolkerFitzpatrick will sink 292 piles along the viaduct with 45, 60 and 80 m spans.
