Obviously this does not give any indication of the complexity of each project. Tunnelling and building railway through a metropolis I would imagine is quite challenging.
- shevy-java 10mo agoStill seems insanely more expensive in the UK. I understand they have a higher cost to carry because their project is indeed more complex, but that's like a almost 13x more expensive variant, while not even being two times the length.
- rsynnott 10mo agoAs far as I can see, the 6bn is _just_ for the big 30km tunnel? Presumably the rest of it cost more.
- orthoxerox 10mo agoSounds like you might want to build the whole HS2 underground to save money.
- monster_truck 10mo agoHS2 is five sets of twin bore tunnels, so there is more "tunnel per tunnel"
