Major progress made on HS2’s Copthall Green Tunnel
33,556
Published 2024-04-11
The Copthall Tunnel is one of five green tunnels on the HS2 route, which are shallower tunnels which will be finished with trees, plants and shrubs on top – helping them blend into the natural landscape. Materials from the excavation are kept on site and then reused on the tunnel surroundings, reducing movement of spoil.
In this latest update, we focus on the progress made on the tunnel such as the completion of the cut, the reopening of the new realigned Harvil Road, the works made on the central section, including the construction of the first vent stack and the work on the soil placement areas (SPAs).
In the Northern SPA, the planting of the first 1,300 plants has began. This is part of 70,000 individual trees, shrubs and bushes that will transform the area into a haven of biodiversity once the landscaping is complete.
The tunnelling team have excavated approximately 500,000m3 of TBM material which is being used to form three mounds within the Southern SPA, keeping the material within site boundaries at Copthall.

This is the infrastructure this country needs, shame Rishi bottled it
-
You guys are amazing. Shame the PM lost his nerve just before you were able to show us all the works. Let’s hope you get to go all the way to Manchester.
-
Great job everybody! I look forward to seeing you bring this wealth of experience and practice all the way to Manchester. Oh wait...
-
Always an excellent informative video which really gives such an insight into many aspects of HS2 which are not usually considered part of building a brand new transport rail link.
-
Thanks for this video and explaining how the works at Copthall are going....
-
It's so beautiful. Really hope it is revived somehow and actually brings wealth and connection to the North.
-
Monumental (and truly impressive) effort for a half-abandoned project.
-
Can't wait for Rishi's pot hole filling videos 😅
-
Nice
-
Well Done all scs team 👏🏻👏🏻👏🏻👏🏻

Really shame that is doesn't go up till Scotland and than some HS3 maybe cause it gives true real prosperity to the UK citizens and economy and if its really expensive i think this and some defence spending that UK at all isn't doing like warships shipbuilding or missile it gives a lot to the UK and this and that is the most citizen spend money that isn't just bulls.. and research and development. So UK gov wake up.
-
We also need reopening to reconnect places. So more importantly load of people who don’t drive can access employment opportunities. Newbury is so car centric it’s so bad. My lungs are suffering as well. Can we not have a high speedish north south route to Southampton from didcot !

I love travelling by train, and I'm thoroughly content with buses and coaches for shorter journeys. But no way would I use HS2! On a normal train journey there's the sheer joy of witnessing the ever-changing scenery and sky. A journey I made from Kings Cross to Aberdeen comes to mind. Thanks to YouTube videos, we now know that a large part of the HS2 route will be underground. So I reckon many travellers will continue to use traditional railway routes - overground!
-
Why is it referred to as Copthall Green?There doesn’t appear to be any place of that name in the area on my maps!
-
Quite a lot of jargon in this otherwise excellent and good length video!
-
HS2 is such an amazing and benefitial project. Shame the short sighted PM decided to drastically curtail this project back to handsacre and left Euston in uncertainty in a quite clearly political move (wouldnt suprise me if it fell victim to the pro-car junk that Sunak did after Tuckwell won in Uxbridge). Lets just hope that at least the Crewe leg gets brought back at the minimum in order to let HS2 truly fufill its purpose.

Fully agree with you regarding inept politicians (all of them). And as you say it was started in London for political reasons. Can't see how the channel tunnel delayed HS2. The original 32.70 billion budget for HS2 was a figure pulled out of the air by HS2 as the government indicated 32.70 billion was the maximum cost they would sanction so HS2 told the government it could be built for that figure. Therefore the 32.70 billion figure has no credence. Which therefore makes a cost comparison between the 32.70 billion hypothetical figure and what it really costs irrelevant. The construction contract HS2 has been let on is the new engineering contract (NEC) option C actual target cost which is the same contract used for crossrail. It requires the Contractors to provide a fully audited paper trail of all costs. It also requires the Contractors to provide early warning notices to HS2 if an event occurs which might increase costs or increase time duration. As the project design is a continuous ongoing exercise the early warning notices become a continuous ongoing exercise so the cost keeps going up and will do so until all design work and all planning requirements become fully known.

Crazy this was even built - literally digging a cutting, before filling it in. It's a lovely idea in an ideal world but this just adds to the balooning cost

I love the railways, and fully support HS2, but can someone please explain why there needs to be so much destruction of the area surrounding the tracks. It's a two track railway for heavens sake, so why is all the earth works along its length 300 to 500 meters wide. And why is there not even a meter of track laid yet?
