Re: A417 Missing Link campaign!
I've imagined how the route would look in the past if it was upgraded to motorway. Most of it would probably be an online upgrade of the existing grade separated D2, with a new access road for local and non-motorway traffic to use, but I'd reroute the main line of the route from north of Blunsdon to Cricklade, where the existing road still has a number or property accesses and non grade separated junctions for country lanes, and I'd designate the now downgraded former route at Blunsdon as part of the local access road, which would probably be of a similar standard to what the access route would be. I think that one of the best methods of getting round the Air Balloon hill issue could be to build a viaduct, which would allow the road to take a much more direct route from Birdlip across to Brockworth, but this would be too expensive to build in practice, especially considering that there's a height decline of around 200m from Birdlip to Brockworth.DB617 wrote: ↑Fri Jul 02, 2021 17:37Same as the M64/A50 really.

Re: A417 Missing Link campaign!
What I find off is you have that pinch point, that round about with the A436 with the sharp fork, but the original route through Birdlip didn't have that, although the original route of the A417 did.
How is it they went about improving the road so much and still leaving that roundabout in place.

Re: A417 Missing Link campaign!
Birdlip Hill is the original Roman Road (Ermin Way) and has a 10-15% gradient, which was considered far too steep for some motor traffic such as goods vehicles. It's possible the MOT originally wanted the A419* to go this way, but were advised by local engineers to route it via the Air Balloon instead.ajuk wrote: ↑Sun Jul 11, 2021 02:20 What I find off is you have that pinch point, that round about with the A436 with the sharp fork, but the original route through Birdlip didn't have that, although the original route of the A417 did.

Not only is the vertical alignment substandard, but the tight turns on the existing line would worsen the situation for all traffic but especially slow vehicles and particularly articulated ones.

The remaining parts of the A419 Cirencester-Stroud and the A417 Cirencester-Goring could simply remain as they are. The orphaned stretch of A417 north of Glaws could then take whichever of A434 or A440 is not used above.
But nah, that would be too tidy!

Re: A417 Missing Link campaign!
A434 would make better sense used for the orphaned northern half of the A34 (Solihull to Manchester, ex Brum)
Re: A417 Missing Link campaign!
That's true - plus, of the two numbers, A440 has the more important appearance, which would suit a fully-dualled M4-M5 link.Micro The Maniac wrote: ↑Wed Aug 11, 2021 16:16A434 would make better sense used for the orphaned northern half of the A34 (Solihull to Manchester, ex Brum)
Re: A417 Missing Link campaign!
You are basically looking for (1) a memorable number that (2) involves minimal renumbering cost and disruption.
The M4-M5 corridor is about equally A417 and A419, but the 'off corridor' bit of A417 is some twenty miles longer, getting nearly as far as Reading. (This doesn't include the bit beyond the M5 as the number there could be retained.) So while the A417 and A419 are equally memorable the A419 clearly involves much less renumbering.
A 'new' number like A434 or A440, on the other hand, involves about as much renumbering as the A419 by length, but all of the renumbering is on the M4-M5 corridor, and is therefore more expensive and disruptive (more signs, bigger signs, etc), whereas for the A419 half the renumbering is off corridor, on a non-primary S2 with much lower signage requirements. A434 or A440 are also arguably less memorable as they aren't currently used on any of the corridor.
So for me the winner has to be A419.

Also it would just be a case of patching a 9 over the 7 rather than doing the whole number, so would be a lot cheaper in that regard too.jackal wrote: ↑Wed Aug 11, 2021 16:45 You are basically looking for (1) a memorable number that (2) involves minimal renumbering cost and disruption.

Why is it that in Britain, doing things cheaply always has to take precedence over doing things properly? Surely if cost is the most important thing, then it should just be left as it is; i.e. a mess!
Re: A417 Missing Link campaign!
The Italian A2 being absorbed into the A1 made sense because it came when the bypass of Rome opened and the two became a single continuous route. At that point the sense that the Milan-Rome autostrada was separate to the Rome-Naples autostrada was lost, so A1 throughout made sense.Owain wrote: ↑Wed Aug 11, 2021 22:13 And yet in Italy they renumbered the original A2 autostrada as an extension of the A1 in the late 1980s, and more recently renumbered most of the original A3 as the new A2.

The Italian A3 becoming A2 makes, as far as I can see, no particular sense and is a change of number for the sake of rebranding the road now it’s been rebuilt. Is that doing something properly? I don’t really know what sense or benefit has been gained by deducting one from the number of the Naples to Reggio road.

Re: A417 Missing Link campaign!
The question has to be what would have been the favoured route from Reading to Cirencester (and hence on to Gloucester) in 1935? The A329/A417 via Goring or A4/A419 via Hungerford? I suspect the latter was always the main route.Ritchie333 wrote: ↑Tue Aug 10, 2021 12:31 * The A419 was renumbered A417 in 1935 to give a continuous number to a Reading - Gloucester route.
Personally if having to chose between making the whole route between the M4 at Swindon and M5 at Gloucester one or the other I would go with A417 over A419. A329 Reading to Goring and A417 Goring to Faringdon then becomes A4417. A417 Faringdon to Cirencester becomes B4650 (the number has already been reserved according to the Sabre Wiki). A329 north of Goring becomes A340.
Re: A417 Missing Link campaign!
The first case made some sense, although I never liked it. I'd suggest that with regard to the second case you make a fair point; had the new A2 started in Rome and ended at Reggio Calabria, forming a complete route, there would have been some logic to it, but as it is I'd agree that it doesn't make much sense at all.Chris5156 wrote: ↑Wed Aug 11, 2021 22:23The Italian A2 being absorbed into the A1 made sense because it came when the bypass of Rome opened and the two became a single continuous route.

Nonetheless, the point I was trying to make is that while we're even agonising over whether it would cost more to patch over three digits (A419) or save even more money by just patching over one (which would no doubt look awful on a sign - A419) other countries don't seem to be obsessed with the cost of replacing signage.
[Not that the Italians bother replacing signage - in 2011 I found a sign for the A2 somewhere south of Rome that had ceased to exist in the 1980s, and oh how I wished I have taken a photo of it! If I could remember where it was, I'd be tempted to go and find it, taking a spanner with me so that I could bring it back and stick it on my garage wall.]
