> [@John\_Bredin](#): > > why a road tunnel instead of a rail tunnel that won’t involve ventilating for hundreds of internal-combustion engines? If they wait long enough so that EVs are the majority of vehicles on the road, they could just prohibit vehicles with internal combustion engines from the tunnel. That reduces the need for ventilation by a very large amount. About 15 to 18 years of delay will do, which is roughly what you typically get for these kinds of projects. In the mean time, they could look at a second Chunnel, which likely has a better payback. ---

Not that easy, in terms of both EU and domestic politics, and of simply gumming up the legislative timetable. The next government is going to have a _lot_ of messes to sort out without creating a new one. ---

> [@Spiderman](#): > > Not sure if you’re being serious or if you’re just… _whooshing_ us. I was being serious about a wind assist since it can noticeably improve the MPG on my Prius when the wind is going the right direction, but I know that forcing air through the tunnel at that speed isn’t feasible in the first place and would probably create hazardous baffles in the airstream. ---

It was part of another study to look at plan for improving transport across the whole of the UK which cost a couple of million. These plans for tunnels and bridges are nothing without improving the roads that connect them. Boris does not have the money for this kind of infrastructure project., especially when it is not connecting major population centres. The big lump of expenditure is tied up in the HS2 rail project, whose latest project cost is ÂŁ107billion. A million or so on a feasibility project is really a political ruse. These things are going nowhere except as material to pad out his speeches. A bit of kite flying to keep the Northern Ireland Unionist politicians quiet. ---

An HS2 project that was recently slashed in such a way that it will still costs a fortune but won’t actually provide high speed rail connections to the North. We really suck at infrastructure. ---

> [@GreenWyvern](#): > > I read somewhere a few months ago (sorry, I don’t have the cite, but it was from someone who knows Johnson) that Johnson wants to build some amazing thing – any amazing thing – so that he will be remembered for many centuries to come, ‘like the Roman emperors’. For that some reason, I’m surprised that Trump didn’t propose building a pyramid for himself. On the other hand, he did want to buy Iceland, so there’s that. Also, the Space Force was probably more for his ego than anything else. ---

> [@Stanislaus](#): > > An HS2 project that was recently slashed in such a way that it will still costs a fortune but won’t actually provide high speed rail connections to the North. HS2 was never going to the North in the first place - it was only ever going to Leeds, which is closer to Southampton than it is to Aberdeen. ---

> [@Stanislaus](#): > > I know this, and you know this, and yet that part of the country is called the North. Language isn’t particularly bound by geography or logic. If this was Wikipedia, there would be a “_who by?_” after the word North there. When Leeds is referred to as being in “the North”, the implication is generally that it is the north of England. This is a thread on the UK infrastructure, so your comment would confuse people not from the UK. ---
