Motorways that pass through every/almost every zone

Post by qwertyK »

M11 - A414, A11, A603, A505, M25
A1/A1(M) - M25,A47,A607,A52,
M6 - M1, M45,A5,A6,A7
A14 - M6,A45,A1,A508

Any more or ones I've missed out?
The M11 was the first to sprung to mind when I travelled down it the other day - maybe it has the record for the most road zones passed in the shortest distance? Not even 60 miles and it passes through zones 1,2,4,5 and 6.

“Roads or Motorways that intersect with other roads from other zones”.

Yes, the M11 actually lies wholly within the 1 zone, while the A1/A1(M) is the boundary between the 6 and 1 zones.

Given that the opening post talks about motorways, this is incorrect, and the 6/1 zone boundary runs along the M1 not the A1.

Logically the winner has to be a 1-zone road, since only roads in the 1-zone can meet roads from any other zone. The M1 meets (for example) A1, M25, A38, A414, A5120 and A63.

Ewww, that's a nasty case of mixy-me-zoneses you've got there! :laugh:

(A282 is the obvious rejoinder to that)

The opening post doesn't say whether it is referring to motorway zones or A/B road zones.

True! And the examples given use a mix of both zoning systems.

The M25, of course, does pass through every (London-centred) non-motorway zone but, disappointingly, doesn't meet any 6-zone roads. Although, of course, it did swallow up a small part of the A6 itself.

Where does it meet a zone 5 road?

If we're looking for "intersects roads numbered after as many zones as possible", it's probably more interesting to look for small and short roads than big motorways (that aren't in the centre of London or Edinburgh). For example, the A6013 meets roads numbered after four different all-purpose zones (A14, A43, B5323, A6003) despite being less than a mile long. Finding other examples like this could be interesting – they're most likely to exist on roads that go a long way out of their home zones.

As for the question in the title, there are 15 zones in total in Great Britain (6 all-purpose and 6 motorway zones mostly or entirely outside Scotland, plus 3 shared zones mostly or entirely inside Scotland). It seems very unlikely that anything could beat the M25, which AFAICT runs through 9 of them (motorway zones 1, 2, 3, 4 and all-purpose zones 1, 2, 3, 4, 6) – the basic issue is that most of the zones radiate out from London, so a motorway would have to go around London to run through enough of them, and there's only one motorway that does that.

I guess if you treat the M6/A74(M)/M74 as though it were a single motorway, it comes close – that touches motorway zones 1, 4, 5, 6, all-purpose zones 4, 5, 6, and primarily-Scottish zones 7 and 8. I say "touches" for a reason, though – although the slip road to the A14 runs at one end under the M1 and thus definitely enters zone 1, the slip road at the other end terminates on the A8 and thus doesn't quite reach zone 8 (and although a spur from the A8 runs under it, spurs aren't zone boundaries).

Seeing as the A1081 used to be the A6 before the start of it warped up to Luton, we could allow the M25 having a 6-zone junction? 😆

It has a secret exit to Sustrans Cycle Route 61, maybe that counts?
