Interesting footage as ever, QM. It's slightly sad to see Sir Dominique shuffling along to his destiny at the knacker's yard 😭 Jamie is right about the two 'peg' legs. I believe they are utilised, one at a time, to support the girder while either main leg is being raised slightly and moved to its new position. In your video at 3:18 we can see the rear temporary leg, with the lower yellow platform, tucked in behind the main support and, similarly, at 4:34 you can just make out the forward peg leg ahead of the main support.
There are two lighter weight subsidiary legs for when they are moving. I think they are painted yellow. They obviously need to move Dominique forward to be completely off the viaduct and those smaller legs will make that possible.
Great video QM, will you be watching as Dominique is dismantled? Looking forward to the time the steel piling and decks are removed from the lakes and we see viaduct in its glory.
Hi not sure I’ll be there.. but I’d love to to catch the last large piece of Dominique being carted off on a super large HGV transporter to Harvil Road…and onto her next adventure! The valley without Dominique..🤣👍 I managed to find a new angle on the viaduct today but my internet is playing up so will try again later…
There's an old, pre-COVID-19 figures of £700 million, that included the architect fees, land acquisition, planning, management, and legal charges, though costs may have gone up in the last eight years. If still £700 million, a £1.25 toll charge, per passenger, for the notional 100 year life of the 2.1 mile viaduct, will likely cover the capital costs.
great views and amazing works. Dominique front leg on "land" now nearest Harvil Road; back leg on the viaduct southern edge. Looks like the workers are ready to dismount Dominique from the viaduct. Those various large concrete pads for moving and adusting the legs for disassembly. An interview with HS2 said it would take a year from now to prepare the viaduct surfaces, and get ready at that time for for installing signalling, track and OLE. So maybe a few more years to be fully complete for the trains.
Hi Carlos yes in a year or so the civils work between Old Oak Common and the chiltern tunnel.north portal could be completed so they’ll be a stretch of the line ready for the railway systems to commence…!! Thanks for watching 🙏
Such an absolutely magnificent structure.

Surprisingly analytical Sir Dave!! I'm impressed!!

Hi Jamie... ah that makes sense thanks for explaining!

Will they manage to extract the sheet piling? You very often can't.
The sheet piling is being cut off at lake bed level.
That sounds interesting but how will they manage to access the lake bed without building another cofferdam ?
If HS2 had been continued up North, were there any other civil engineering challenges to match this that would have been built?
I’m not very familiar with the original HS2b plans but it would be great to see construction continue north of Lichfield!
Wot was the cost to build this then as we will have to pay for it some how you know the line
I’m not sure it’s publicly available that info. I try not to think about it but I’d say it’s a minimal proportion of total government spending.

I once read the viaduct cost 3 billion and the Chiltern tunnels about the same figure. Not sure if the cost includes the track and overhead cabling.
Wish were was music 🎶 too you know
What music would you like haha, good try, perhaps one day… you never know..! Thanks for watching, it’s appreciated. 👍
Beethoven's 5th or Whigfield's 'Saturday Night'? Something in-between maybe?
