HS2 designers and engineers working on five key viaducts have cut their carbon footprint by up to two thirds (66%) by adopting an innovative ‘double composite’ structure which uses significantly less concrete and steel than a more traditional design. HS2 engineers at Westbury on the Buckinghamshire/Oxfordshire border have already begun Read more…
HS2 has moved the first huge viaduct section into place over the motorway network in North Warwickshire, a milestone for the project’s Delta Junction as HS2 reaches peak construction in the region. Contractors have used a specialist push-pull technique to move the 84 metre, 300 tonne steel viaduct section into place Read more…
