Zonal extremities
I'm guessing that there's some A3x roads that are a long, long way from the A3, so perhaps something in Cornwall?

Re: Zonal extremities
There is no contest regarding zone 3 - it's the A3111 on St Mary's in the Isles of Scilly. What I'm less certain of is whether somewhere in the far north of zone 8 is further from anywhere on the A8.LoopyUpholland wrote: ↑Wed Jan 05, 2022 12:20 Looking at the map of zones has made me wonder something: which road is the furthest from its zonal 'parent', while being totally in its own zone without leaving? Roads such as the A14 or A38 wouldn't count here.

Re: Zonal extremities
Not by a long-shot.
The distance from where the A3 meets the A27, to the furthest point of the A3111, is 242.3 miles.
The distance from the A8 at Greenock, to where the B874 meets the A9 in Thurso, is 188.6 miles
Even the distance from the A8 on West Maitland Street in Edinburgh, to Eorapaidh (Isle of Lewis), on the B8013, is only 210.2 miles.
In comparison, the distance from the A3111, to the A3 at Elephant & Castle, is 293 miles.
A roads: 71/71
B roads: 181/181

Re: Zonal extremities
It's a long way from Thurso at the end of the A9 to the northernmost part of the A968 in the Shetlands. I'm not saying it's further than Portsmouth to the Scillies, but it's a long way. The B9087 adds a bit more.A72 wrote: ↑Wed Jan 05, 2022 13:04Not by a long-shot.

Re: Zonal extremities
Zone 9 perhaps suffers a bit here due to the curtailment of the southern section of the A9 so maybe it's fair to consider some other "parent" roads?

Top of A968 to...
End of A9: 178mi
Start of A9: 347mi
Start of M9: 349mi
Start of A90: 357mi
So zone 9 actually wins outright if you consider the start of the parent road. (There might actually be a more south-westerly point of the A9 that does even better.)
This is actually quite an interesting thing to think about for getting the "feel" of how large certain parts of the UK are relative to each other.

Re: Zonal extremities
The 9-zone can win - but only if we go back to 1935, when the A9 ended in Inverness. The B9087 existed then, though shorter than now. It's 258 miles as the crow flies from Haroldswick to Inverness, marginally beating the 242 miles from Portsmouth to St Marys.
The 3-zone is unusual in that neither of its boundary roads are very long, while the zone itself is. Somerset, Dorset, Devon, and Cornwall have the zone boundaries as the sea, not a road - on both sides.

Re: Zonal extremities
- I can understand why the A414 goes as far east as Chelmsford since pre-M25 it would have been a useful route across the north of London, but why take it all the way to Maldon?
- The A614 goes an unusually long way into the 1 zone for a not particularly important route, as does the A272 into the 3 zone (though for the latter, the western end of the route did fit better with the rest of it at the time of classification.)
- We all know about the A361 of course.
- After having been the main south coastal route for the entire route from Pevensey to Southampton, the A27 suddenly swings around the north side of Southampton, then runs away from the coast to Romsey.
- The A52 running up the Lincolnshire coast is virtually a completely different route from the rest of it, and would look especially odd had the rerouting up the A523 to Manchester gone ahead, resulting in the route being a long U shape!

Re: Zonal extremities
The A614 is a bit of an odd one for a long distance route, connecting up with not very much. It was actually much shorter until the 1990s, terminating at Howden. It has since eaten up part of the A163 and A166 to get to Bridlington.Mapper89062 wrote: ↑Wed Jan 05, 2022 18:13 [*]The A614 goes an unusually long way into the 1 zone for a not particularly important route, as does the A272 into the 3 zone (though for the latter, the western end of the route did fit better with the rest of it at the time of classification.)

Re: Zonal extremities
I mourned it every time I drove over the Huntingdon Viaduct as I was one of the first to drive it from the M11 to Alconbury in early 1980.
https://www.sabre-roads.org.uk/wiki/ind ... title=A604
From the SABRE Wiki: A604 :
The A604 was an important major cross country route across East Anglia from the 1930s to the 1990s. At one point it was one of the main roads for traffic heading from the Midlands to the ports at Harwich and Felixstowe.
Most of the A604 was created in the 1935 Road numbering revision which joined several local cross-country routes, including the original A604, to form a long-distance road that could act as an alternative to the A45. The A14 was created partly out of

Re: Zonal extremities
I actually first drove part of it in 1973 on my way back from an interview in Cambridge, up the A604 to Godmanchester , over the town bridge to Huntingdon and up what was then the A14 (Ermine Street) through the Stukeleys to the A1 at Alconbury. This was one of my earliest long range drives in my trusty Hillman Imp (EMX 724J). At that time of course it was S2 with lots of flat junctions

Re: Zonal extremities
Aside from the bit where the A1 gobbled up part of it (between Blyth and Clumber Park) to bypass Doncaster and Retford, it's a continuous route starting in zone 6.jgharston wrote: ↑Sun Jan 09, 2022 04:53And should really be numbered A164 (posts passim).ravenbluemoon wrote: ↑Fri Jan 07, 2022 17:39The A614 is a bit of an odd one for a long distance route, connecting up with not very much.

Though the section between Nottingham and the A1 is clearly important and busy (if not particularly fast due to Sherwood Forest traffic, SPECS, low speed limits etc) it doesn't feel as though it's part of a particular route to get from Nottingham to Bridlington, maybe because the part alongside the M18 is presumably more a local route, and not necessarily worth having a 3 digit number, making the section from the A614 to Bridlington (which as has been said is an extension of the original number anyway) a 2nd route of actual importance. It'd be a faff to renumber everything which is probably why it hasn't but the bit from Blyth to Howden could even be a B road and then you'd be able to give the Yorkshire section an A1xx number, in Notts in an ideal world I'd probably swap the A60 and A614 numbers north of Redhill as that matches more their relative importance.
Of course, the A52 (also mentioned) was also heavily extended at the Eastern end, originally ending on the A1 at Grantham, the rest was A152 then A154 or something up the coast. It isn't really the obvious route to Mablethorpe or Skeg either, though the roads in that part of Lincs aren't exactly amazing to begin with. It just seemed they wanted to put a 2 digit number to the coast like a fair amount of the others do.
Never argue with an idiot. They will bring you down to their level and beat you with experience.
Re: Zonal extremities
Considering that the A60 number seems rather 'wasted' on its present route, I think it would make some sense to swap it with the A614 in Nottinghamshire as you suggest, but also to swap the whole route to Bridlington.ForestChav wrote: ↑Sun Jan 09, 2022 14:16 Aside from the bit where the A1 gobbled up part of it (between Blyth and Clumber Park) to bypass Doncaster and Retford, it's a continuous route starting in zone 6.

Bridlington is quite a significant destination - surely as much as Skegness and more so than Mablethorpe - and the road to that point from Goole is pretty good. It's green-signed too.
