Signed route back on
When you leave a dual carriageway at a grade separated junction you very often reach a roundabout or similar with a helpful sign like this random example showing the routes available in the conventional manner. There's also an exit from the roundabout back on the dual carriageway and this is shown but is not labelled.
So leaving the M18 northbound at junction 2 the roundabout sign offers you A1(M) north or south but straight on back to the M18 isn't labelled.
But leaving the M18 southbound here the option to return to the M18 is shown.
Why? Are there any other examples of this?

Re: Signed route back on
Botch surely. There is no real reason why a grade separated junction can't show that with the simple diagrams as per your first links.
Here is an example near me. No reason here and would save a load of space on the sign.

I personally think that signage of dumbbell junctions need be altered. Currently in most circumstances you cannot show both roundabouts, however there must be a simple and easily understandable way of showing a standard dumbbell interchange.
OP, yeah thats a botch.
Some odd GSJ examples I know of:
https://www.google.co.uk/maps/@51.06735 ... 312!8i6656 - Has signed back onto the Main route, although here it is needed since its two GSJs weaved into each other.
https://www.google.co.uk/maps/@51.15861 ... 312!8i6656 - Leaving Gatwick Terminal shows the M23 Spur / A23 Spur as a GSJ, although it is just a normal roundabout
https://www.google.co.uk/maps/@51.12761 ... 312!8i6656 - this sign seems to completely ignore the GSJ, and doesn't even show the road exists to the south! The other direction again doesn't show the GSJ but does show the southern arm.
https://www.google.co.uk/maps/@51.13261 ... 312!8i6656 - Round seems to of turned into square, and apparently the GSJ only appears on the right, but not left! - Also is meant to be non-primary. This sign may soon be gone since they are replacing the limited access junction adjacent to that sign. The sign approaching from the other direction was basically the same, however was replaced a few years ago with the introduction of a new roundabout.
Re: Signed route back on
There's this one here, on the A53.
The reason it shows the road ahead is cos the sign is a false-colour copy of an older sign (go back in time and you'll see it) which was put up before the flyover was put in. Either that or the Council knew there'd be the constant structural problems the flyover is having and so kept it there for when all traffic was forced to use the roundabout.
There's something similar coming the other way.

Re: Signed route back on
I wonder if they're expecting people leaving in error wanting the M1 - they see A1(M) but aren't really paying attention and think it said M1 so take the exit. Then they get here and there's a clear sign that the M1 is straight on.the cheesecake man wrote: ↑Thu Aug 06, 2020 19:11 But leaving the M18 southbound here the option to return to the M18 is shown.
The sign on the other side of the roundabout (for traffic exiting the westbound M18) does not sign the route back on to the M18, which would agree with that suggestion.
Re: Signed route back on
It's also botched as the hole in the second roundabout is not in the right place.

Re: Signed route back on
I hate this one, but understand why it's there, as there is a sliproad that joins the M25 offslip: https://www.google.co.uk/maps/@51.44162 ... 312!8i6656

Re: Signed route back on
Problem is, which is the second roundabout? There is no indication on the sign of where you are approaching from.c2R wrote: ↑Fri Aug 07, 2020 07:52It's also botched as the hole in the second roundabout is not in the right place.

Re: Signed route back on
That's an interesting suggestion. The only idea I had was that it was done for high vehicles avoiding the flyover in strong wind, but that doesn't make sense in one direction only.SteelCamel wrote: ↑Thu Aug 06, 2020 22:07I wonder if they're expecting people leaving in error wanting the M1 - they see A1(M) but aren't really paying attention and think it said M1 so take the exit.

I noticed today the unusual inclusion of M1 on the exit sign and this seems to support your idea

Re: Signed route back on
And it should say "London, Sevenoaks A21" as Tonbridge is not a primary destination.Nathan_A_RF wrote: ↑Thu Aug 06, 2020 19:18 Botch surely. There is no real reason why a grade separated junction can't show that with the simple diagrams as per your first links.

There's this on the A31/A338 junction for Bournemouth. Two reasons I can think of - a) the junction was previously a standard roundabout, and this sign is just a copy of the existing one, and/or b) the slip road from the previous junction for the B3081 has only just merged in, and traffic wanting the A31 might not have been able to get into the correct lanes in time.

Re: Signed route back on
All I can think of for that one is that it may be to help drivers going to the service station remember the route back onto the motorway. But it's a pretty weak reason!Big L wrote: ↑Tue Aug 11, 2020 09:30M74 J13 including signed route back the other way. Other direction does the same.

Re: Signed route back on
Not quite the same, but after passing this gantry for "Southampton, Fareham M27", traffic on the slip road passes a sign for "Fareham, Southampton A27" (also seen in the link).

Re: Signed route back on
I spotted this one at M1 J37, complete with wrong font.
My guess here is that some inattentive drivers wanting Manchester and intending to use M1 and M62 might leave by mistake on seeing the Manchester A628 sign.

Re: Signed route back on
This one was mentioned in another thread I contributed to. The A31/A331 junction ADS gives you the route back to the A31 London, that you just left. Definitely a case for a stub arm here.

Re: Signed route back on
That one is an exceptional case though, as the straight on option is usually returning to the dual carriageway, but instead it's the right hand arm here. I think a sensible decision.
Re: Signed route back on
Not quite the same, but there's a sign basically pointing to the southbound carriageway on the northbound A90 (and indeed the reverse heading southbound). I do remember reading a piece about the reasoning behind this junction (basically trying to permit safe access to the tractor and truck dealers without going to the expense of having a GSJ), but have no idea where I may need to look to find that again now.

Re: Signed route back on
M5/M50 junction, although that's signed in that way due to the exit slip of the services joining the sliproad.
British & Irish cities driven in - 48/75
England - 36/52, Scotland - 7/7, Wales - 5/6, NI - 0/5, RoI - 0/5

As you sort of say these are both straightforwardly for right turning traffic coming coming from the dealership and from the LILO respectively are they not?orudge wrote: ↑Thu Aug 11, 2022 16:37 Not quite the same, but there's a sign basically pointing to the southbound carriageway on the northbound A90 (and indeed the reverse heading southbound).
