- The team delivering HS2's Wendover Dean Viaduct have completed assembly of the first of nine piers that will support the 450-metre long viaduct deck.
The piers are made up of a series of hollow pre-cast concrete shells that are placed on top of each other and filled with concrete and steel reinforcing. This approach was chosen to enable a crisp, clean external finish to the concrete, cut the amount of work on site and reduce disruption for local residents.
Nine evenly spaced piers will support the deck of the viaduct and will be placed to carefully reflect the near symmetry of the ground beneath.
Early in 2024, HS2 Ltd’s main works contractor, EKFB - a team made up of Eiffage, Kier, Ferrovial Construction and BAM Nuttall - will launch the first of five 90m long viaduct deck spans out onto the viaduct piers.
The huge spans are assembled on site, with pre-cast concrete sections added to form the box-like structure. These will then be slowly pushed out from the north abutment onto each of the concrete piers.
Once complete, HS2 will link London, Birmingham and the North - dramatically improving journeys while freeing up space for more freight and local services on the existing network. Trains will be powered by zero-carbon electricity from day one and carry up to 1,100 passengers.
The double composite approach is set to save an estimated 7,433 tonnes of embodied carbon within materials - the equivalent of someone taking 20,500 return flights from London to Edinburgh - and help HS2 achieve its goal of halving the amount of embedded carbon in construction.

Please do a video on the Solihull Interchange. Lots of work going on there no videos
It is not Solihull Interchange, the Station due to it's closeness to Birmingham Airport and Birmingham International Station and the fact it is closer to Birmingham than Solihull and not every one knows of solihull it's official name is Birmingham Interchange. Solihull Station is in the Town Center on the Chiltern line from Birmingham Snow Hill to London Marelabone and the powers to be IE HS2 Ltd have called it Birmingham Interchange to prevent confusion.
we need more update videos!
So what parts are going to be done now wich parts have been cancel
Nothing has been cancelled in this area of HS2 only the part from Lichfield to Manchester
As someone who works in the construction industry, it really baffles me when I see so many iterations of HS2 viaducts being used along what is left of the project. Couldn’t they stick to homogenous viaduct designs throughout the route, not to mention the vanity of having so many unnecessary tunnels (just Check the HS2 website)? No wonder the budget has ballooned out of control. Í´ve used high speed rail in Italy and Spain many times and there are two stark differences between what I see in HS2 and those countries, hardly any tunnels unless you have to overcome mountain ranges, and all viaducts are purely functional, not aesthetic and homogenous to standardize construction methods. If there is ever going to be any future inquiries about the failures of HS2, many of the issues I have raised should be looked at. I just hope that any future UK governments dońt shy away from investing in future high speed rail though, and they hopefully learn from these mistakes.
Ah, but the tunnels were necessary; not in an engineering sense, but in a political sense.
@@peterrobinson6872 yes they just kept moving the goal posts regarding the brief of the project. Politicians were naive enough to think that the budget wasn’t going to sky rocket, and the civil servants at the ministry of transport should have doubled down on this issue. Which begs the question, why was a company set up (HS2) just for the high speed rail? For instance in Spain all transport infrastructure projects are closely monitored within the ministry of transport, pre planning of routes with no political interference. I fully understand that the UK is far denser in population than in Spain and that in certain areas like in London was inevitable, but I cannot fathom why a feasibility study was not carried out to avoid at all costs areas of outstanding beauty like the Colne valley due to the amount of work and excessive engineering practices that have been used which could have been avoided. On a positive side, now that we have AI, if they intend to extend high speed rail through other routes maybe this could be a great tool to determine the best routes that have the path of least resistance, factoring in geography, road and rail connections and urban areas along routes, until you reach the cities of course. Satellite imagery can be used as part of the initial feasibility study and incorporate AI for the exercise. Any HS2 managers should take note of this if they read it please pass it on to any civil servants in the ministry of transport.
@@jonathanfreyone526i can sort of see what you mean with the company/business bit. The politicians interference has been the downfall of HS2 (quite literally), the constituents whining is what led to the ‘vain’ tunnels, the constant questioning is what led to the budget increasing. It also led to the horrible media storms, i really feel for everyone that works at hs2 because right wing nut jobs now berate them for being a waste of money because of the lies they’ve been told in the papers. I think that infrastructure should be taken away from the party politicians, and neutralised. Hand it off to a semi-independent body like in Spain, depoliticise it, stop it from being used as a tool to get one over. infrastructure is too important for that. We forget how important it is. The cancellation of HS2 will be one of the decisions that make my generation look down on the older ones, for forgetting us, for being more self-interested. You need an explaination for a generational divide? Here’s a perfect one! however, i do raise issue with your description of the Spanish and Italian high speed rail networks. I was on the Italian one only a couple of weeks ago, and it is mainly on viaducts and in short tunnels through hills. The viaducts for HS2 had to be aesthetic because people would whine if they weren’t. HS2 is a product of the British people’s and media’s pessimism, inferiority syndrome and selfishness. Labour must learn from the mistakes, restart it, all the way to Leeds, but hand it off to a separate body, try to keep it quiet, out of the public eye. People were whining about the cost, but dont forget it was a 30 year project, with a return on investment at the end. Cancelling it to Leeds was the worst decision Boris ever made, setting a precedent that infrastructure could be cancelled halfway through, which is never a wise move.
@@cum3173 I wouldńt worry regarding the future of high speed rail. The likelihood is that Labour will rebrand the Birmingham to Liverpool/Manchester route as HS3 and choose an alternative route, and a holistic high speed plan is put in place for the rest of the UK. Remember that phase 1 is scheduled for completion for 2033 and the current changes are likely to take at least a year of so to design and plan. I already saw another CZcams video about railway enthusiasts highlighting the problems the HS2 connection will cause on the Great Western line, it will create a bottle neck of trains in an already saturated railway line. As far as the usage of tunnels and viaducts, I dońt dispute what you’re saying. But as you said the tunnels are short in comparison to HS2 and as far as viaducts are concerned, they are homogenous in design to standardize construction methods. On the other hand the HS2 viaducts differ from one area to another which is crazy from a cost perspective. Anyways, hopefully lessons have been learnt from this fiasco.
right ,that is how the it should be done ,small viaduct like that all the way though,and at that height,expect it is to easy,because high power people want tunnels,and hs2 have not got a clue
What will become the worlds most expensive cycle path and walkway😱🤦🏻♂️
Made a dreadful mess around Wendover. For an expensive
railway that won't be any faster to Birmingham. It will benefit about 15% of the population at best estimate.
More over budget vile destruction
You Misery !. Fine young engineer building a fine construction that will be providing transport a long time after we are all gone.
@@JohnHoward-wc9kkIt’s a total waste of money, won’t benefit anyone, and has caused environmental damage that will never be restored.
@@daveallen2565 Please can you elaborate on "won't benefit anyone", I'm guessing you missed the increased rail capacity as a benefit we desperately need? The reason it's costing so much is because whilst it is damaging the environment to start with, they're putting a lot of money into ensuring the environment around the project is better than when it was before the project started, e.g. new forests to not only replace ones destroyed, but to supplement and add additional woodland, new wetlands, etc.
@@rubberduck3788 I totally agree with you, it's a shame all these mitigation works have not been given a higher profile to the government and everybody else when counting the cost of HS2.
@@daveallen2565 too right my friend
