Rugby services shown as a non-motorway service area.

Some other interesting changes and omissions:

No sign of the A30 or A391 improvements in Cornwall.

The proposed lines of the Arundel bypass and LTC have been deleted. They have been shown for the last couple of years. The A12 realignments between Chelmsford and Colchester continue to be shown as proposed.

A new A-road to the northeast of Aylesbury. No doubt another development road for more sprawling car-dependent housing estates rather than any functionally useful bypass.

The East-West railway has gone from being an almost intact disused railway to being a dotted line, presumably an under construction railway. But no such dotted line for HS2 which you might expect to make an appearance by now.

A487 Caernarfon bypass shown as complete.

No roundabout for the M181/A1077(M).

The link from the A9 to A94 north of Perth has regressed from under construction to proposed.

I'm sure there will be many more changes i haven't picked up on yet.

This (along with Truvelo's comment about the 2021 map not showing a roundabout on A449 north of Penkridge) isn't actually surprising.

At that scale, roundabouts are generally only shown where two roads marked on the map meet at a roundabout. There are a few exceptions to this, for example, on A460 just south of M54 J1.

Another one that's been shown for the last couple of years but has disappeared this year is the M54-M6 Toll Link. It's been really hard to see as the A460 label hides it, but it's definitely been there on the 2020 and 2021 editions.

One more for the "additions" list is the Stafford Western Access Route, and on a more off-topic note, so has a new tram stop in Birmingham.

They're showing the Five Ways tram stop, which isn't open yet. They also don't show all the tram stops in the city centre, but that's probably understandable as they'd obliterate all other detail.

An interesting omission is any indication of county/unitary authority boundaries (national boundaries are shown). I doubt that it has anything to do with the scale, which is clearly sufficient.

The 2023 edition was released yesterday, and found its way onto SABRE Maps this afternoon.

The Poynton Relief Road's there (though the old road is still marked as A523...), but what else?

I've found the Forder Valley Link Road in Devon, and the A6120 realignment in Leeds (but with the old road still a primary A-road). There's also the new link road in Northallerton, the Haudagain bypass in Aberdeen (alongside the downgrading of the roads in the city to non-primary at last), the A325 downgrade through Farnham, M11 J7a and the A1307 viaduct replacement route in Huntingdon.

New on 2023 is showing the Grantham Southern Relief Road, East of B1174 as construction and West as primary open, which it did last year.

Things Missing from 2023:
A2300 not shown as dualed
A27 Roundabout at Lancing not shown (still under construction)
A23 south of A270 still showing old layout
A264 new (2019) roundabout East of M23 J10 not shown
A259 dualing at Angmering and Littlehampton not shown (completed few months ago)

Just noticed that the A22 in East Grinstead has its strange junction marked as a grade separated junction with limited access, I guess in some definitions it is grade separated, but only due to the geometry of the old railway, and not to increase throughput.

A6211 changes between 2021 and 2022
C, E flat and G go into a bar. The barman says "sorry, we don't serve minors". So E flat walks off, leaving C and G to share an open fifth between them.

I've found that OSNI have released a new map (May 2023) at 1:250k scale as OpenData called "Eire Thuaidh", ie. Northern Ireland, with all the place names shown bilingually.

Excellent I thought, a great new map for SABRE Maps!

Then once the work was done, I looked more closely. It's officially the worst map I've ever seen created by any of the three Ordnance Surveys. You can amuse yourself for hours finding all the things that are wrong - for example, where's the M3 and the Lagan Bridge? Where's the A1 Newry Bypass? Why is the A8(M) not shown as a motorway?

It's on the 1:250k 2023 layer for you all to facepalm at...

It looks more like it's from 1973 than 2023. It's not remotely up-to-date.

It's an odd one.. the A55 to the south of Belfast as it's pre upgrade number of B205. Then there are some places on there which should have Irish names but don't so it's not really even doing that fully. It definitely is right up there in the not too be trusted category of maps

I do like the attention to detail on the demarcation of the two different grid systems though

I'd estimate the map at 1988 or so, and what's more we used to own a copy of this map. It was "Eire Thuaidh", a joint OSNI-OSI production, and in the early 1990s it was printed in a card cover with a Celtic cross on it.

Found the cover at Library Thing
And even better... my estimate is bang on. The PDF of the map is available at ARCGIS and I am feeling clever.

Not sure where to raise this, but on looking at this, and looking around, at e.g. 1:250k 2010 layer - and others, e.g. various OS Quarter Inch series - the boundary between where it gives grid references for locations (alongside lat & long) using Irish and GB National Grids is wrong - it is giving Irish (single letter) references rather than GBN (two letter) ones for significant parts of SW Scotland and West Wales (part of Pembrokeshire).

There is - as marked on the OSNI Eire Thuaidh map (and some others) - a carefully defined boundary between the two grids, running down the Irish Sea: which is where those to whom it really matters change system, and I would suggest this is what should be used.

Checking in more detail (on the Sabre Maps page), it appears to be giving Irish refs throughout the 400*500km Irish Grid 'space' (up to 400/900km E), in preference to GBN ones (even in GB), rather than using the defined boundary (or even a simplified variant of it).

But what should be done is arguable (given that I suspect working out which side of the boundary points are is net exactly easy): possibly in the 'common area' both should be given.

The map looks at least 15 years old. There's no N2 Castleblaney Bypass, which (IIRC) opened in 2007.

At least this does demonstrate why Irish maps from the 1990s and 2000s are more interesting than British ones from the same period as so much more building was happening.

Yes, it looks like that's a bug that's been missed as in those areas it should be giving both grid references as we calculate them both and display when we get a sensible answer.

The SABRE Maps Co-ordinate Finder gives both, as well as a ton of other systems both modern and archaic.
