A 3.4km viaduct is being constructed across a sequence of lake within the Colne Valley to raise the HS2 rail link within the outskirts of London

The first pier has been solid by specialist contractor Kilnbridge for HS2’s main works contractor Align JV – a bunch made up of Bouygues Travaux Publics, Sir Robert McAlpine and VolkerFitzpatrick.

Weighing in at spherical 370 tonnes, the six-metre huge bolstered concrete pier became as soon as solid in situ.

Each and each pier rests on a put of concrete piles sunk up to 55 metres into the bottom. The root work started earlier this 365 days and would require the construction of 292 piles and 56 pile caps across the entire dimension of the viaduct.

HS2 Ltd project consumer David Emms acknowledged: “The Colne Valley Viaduct will be one among HS2’s most iconic structures and it’s astronomical to gaze how worthy has been finished already. I’d eradicate to thank the entire group for the large quantity of labor they’ve done to catch us to this level.”

Align project director Daniel Altier added: “I in actual fact beget dinky doubt that the viaduct will change into one, if no longer potentially the most placing component of HS2 phase one, as soon as total. The skill this is also constructed goes to be equally provocative for engineers younger and passe. The sections for the deck will be fabricated at our main construction put of dwelling to the west of London appropriate contained within the M25, and the exercise of an mountainous launching girder, the deck will be fashioned from north to south, along the twin carriageway of the route, thereby keeping pointless construction web site visitors off the roads.”
