Heathrow’s Third Runway – run away now?
I’ve just taken a butcher’s at the plans for a third runway at Heathrow, which is a news story that has been rumbling away in the background for years and years. The third runway is the one on the left in the graphic above, with – pay close attention – the M25 running underneath it.
What prompted me to look was an article in The Sunday Times (that’s an Apple News+ link, sorry) about some billionaire’s plan to take over the scheme and get a shorter runway built more quickly. This is because the existing plan – approved by this fucking government – involves the re-routing of the M25.
Presumably a shorter runway would be used by smaller planes question mark.
I’m very late to this party, obviously. I drive around the M25 quite often (not as often as people who do it every day, obvs), and 90% of the time, I choose the Dartford crossing way, because (especially since the introduction of numberplate recognition) as painful as it is, it is not as painful as driving past both Heathrow and Gatwick. That stretch of road between the M3 and the M40 is best avoided.
In a sane universe, this wouldn’t be a discussion. The bleating about economic growth in connection with air travel just makes you tear your hair out. We should be doing less of this. As I was pondering Peak Oil the other day, I didn’t even mention air travel, though it was in the back of my mind. This third runway is supposed to be opening by 2035, and you think, how is this even something people are talking about? How will they still be pulling oil out of the ground to fuel an expansion in the use of planes in 2035?
I wonder, too, how many people are aware that these third runway plans involve sinking that awful stretch of the M25 into a tunnel? So that planes can come in to land/take off over the top of it. And this billionaire who seems to be muscling his way in (why? because money) is suggesting just building the shorter runway so that the M25 can stay where/how it is. Can you imagine? That would presumably mean planes coming in (or taking off, unsure of direction) at incredibly low altitudes above all that usually stationary traffic. Visions of Kegworth.
Now, I happen to have been following the Black Cat Roundabout scheme quite closely. Here’s what the scheme is supposed to look like when finished:
So in the middle, left to right, is the A421, which instead of coming to a halt at the traffic lights on the old roundabout, is going to fly over the top, a non-stop dual carriageway all the way to Cambridge and the M11. It’ll be a more-or-less non-stop link between J13 of the M1 and J13 of the M11 at Madingley.
Running top to bottom is the A1, Great North Road, which instead of coming to a halt at the Black Cat traffic lights will be sunk beneath the roundabout, which will pass over the top of it.
So this scheme turns out to be fairly similar to the propsal of sinking the M25 underneath Heathrow’s 3rd runway.
Here’s what the Black Cat scheme looked like a couple of days ago, in the latest Wandering Northerner drone-shot video:
This is about a year in to the construction, by the way. Maybe more? And about another year to go. So now I want you to imagine them doing that ↑ to the stretch of the M25 next to Heathrow, quite close to the junction with the M4. Which is described like this on the official Third Runway web site:
“Delivered offline to maintain traffic flow.”
Uh huh. Yep. That’s the sort of thing you say in a planning meeting, but a glance at the scheme and a moment’s thought is enough to make me very sceptical. There is no “delivered offline” when it comes to the M25. Also, you’re speaking metaphorically, and your metaphor makes no fucking sense. What is offline? In this case? What is delivered? And most expecially, in this mixed metaphor: what traffic flow? Because you look at that Black Cat scheme and you see the tiny tiny lorriess which are actually huge lorries, and the vast quantities of topsoil being moved, and the substrate gravel being delivered, and the rebar being pounded into the ground, and the concrete being poured, and the steel bridge beams, and the massive engineering going on, and the excavation, the culverts, the drainage…
Like hell is this going to be delivered offline to maintain traffic flow.
So a shorter runway? And we’ll deal with the air disaster when it happens, I guess.
