HS2 completes epic 8 month Wendover Dean Viaduct deck slide
HS2 today revealed stunning new timelapse footage showing engineers carefully sliding a 3,700-tonne viaduct deck almost half a kilometre uphill into position near the town of Wendover in Buckinghamshire.
The deck of the Wendover Dean Viaduct – which stretches for 450m – was assembled in three stages, ranging from 90m to 180m, with each one pushed out from the north abutment before the next section was attached behind it.
This painstaking, eight-month long process meant that the weight of the deck increased with each push, up from an initial 590 tonnes at the start of work in January - to 3,700 tonnes by the time it reached the south abutment on Saturday.
It is one of 50 major viaducts on the HS2 project – which is designed to improve connections between London, Birmingham and the North while freeing up space on the most congested southern end of the existing West Coast Main Line.
