HS2 completes 3,130 tonne second Wendover Dean Viaduct deck slide

New footage from HS2 shows the latest stage of a complex year-long project to slide almost half a kilometre of bridge deck into position, high above the Misbourne Valley in Buckinghamshire.
Over a 20-hour period in May 2024, engineers working for the high-speed rail project carefully slid the 3,130 tonne structure 270 metres, using Teflon pads to reduce friction - a material usually found to the surface of a non-stick frying pan.
The deck of the Wendover Dean Viaduct - which will eventually stretch for 450m - is being assembled in three stages, ranging from 90m to 180m sections, with each one pushed out from the north abutment before the next section is attached behind it.
This painstaking process means that the weight of the deck will increase with each push, up from an initial 590 tonnes at the start of work in January - to 3700 tonnes by the end of the year.

More great achievement from HS2 as we move forward to a cleaner future of High Speed Rail travel, taking cars and lorries of our congested roads while protecting our environment.

I see you're STILL posting nonsense & STILL haven't done any research. HS2 WON'T be "cleaner" during its expected 120 year lifetime. Research by the DfT & the Road Haulage Association shows that even if HS2 had been built in full, traffic on the M40 & M1 would decline by less than 1% & it'll have ZERO affect on domestic flights. As for the environment - are you aware that HS2 Ltd have already incurred numerous fines for multiple breaches of environmental issues? Thousand's of trees planted along the route in Warwickshire where the vast majority perished because of a lack of aftercare. The pollution of streams, rivers & other waterways with toxic chemicals. The bulldozing of mile upon mile of hedgerows containing nesting birds when they specifically promised to wait until the nesting season was over .. the list goes on.

Phase two WON'T happen! In a January interview, Sir Keir Starmer stated that when Labour win the next election, they've got no intentions of reviving any of the scrapped sections of HS2 because .. "it wasn't possible to do because the government have blown the budget & contracts are going to be cancelled", which is excellent news as HS2 is an environmental disaster of epic proportions & Britain's biggest infrastructure mistake in half a century.

Indisputably fantastic engineering but a tragic shame all this money skill and technology wasn’t directed towards projects we really really need such as producing sustainable energy alternatives, our rapidly declining water services and local transport improvements, which HS2 is not. Environmentally catastrophic and so much else in desperate need of investment and improvement in our country.

You are always concerned about the environmental damage caused by HS2 construction. I class it very small by the way, when the remedial works are carried out. What's your plan for reducing short haul flights in this country ? taking heavy lorries off the motorways ? transporting an increasing population ?.

@martinsloman6905 2 ай бұрын

I believe the figure for the whole route (phases 1 and 2) amounts to 44 ancient woodlands, which would actually lose some trees over 345 miles of route. The total loss of this woodland would be 58 hectares or 0.018% of the UK total. By comparison, the Lower Thames Crossing will remove 57 hectares in 14.3 miles.
