To carry the railway 3.4km, 56 piers shall be constructed with an general bridge top of 10 meters.
To calculate what number of and the depth of the piles to assist these piers, checks have been carried out by sinking 12 piles throughout two areas. Following these checks, 292 piles shall be pushed 55m into the bottom to assist the piers, with this work to accomplished over the subsequent yr by three massive contractors made up of Bouygues Travaux Publics, Sir Robert McAlpine, and VolkerFitzpatrick.

HS2 Ltd’s Central 1 Project Client Rohan Perin stated: “The Colne Valley Viaduct shall be one in every of HS2’s most iconic buildings and it’s nice to see work now beginning in earnest. I’d prefer to thank the entire workforce for the massive quantity of work they’ve accomplished to get us so far.”
Align’s Project Director Daniel Altier stated: “I’ve little doubt that the viaduct will turn into one, if not essentially the most placing aspect of HS2 section 1 as soon as full. The approach will probably be constructed goes to be equally fascinating for engineers younger and previous. The sections for the deck shall be fabricated at our important building website to the west of London simply contained in the M25, and utilizing an enormous launching girder, the deck shall be shaped from north to south, alongside the road of the route, thereby conserving pointless building visitors off the roads.
I’m delighted that in the present day we’ve got reached this necessary milestone in the viaduct’s building.”
