OS One Inch 7th Series map coverage

[Steven]

It actually works for me on Chrome - I have just tried it and I can see the series of years along the top unlike Internet Explorer. On that I got a full map of the UK rather than just isolated sheets, but it looked to be from about 1960 and there were no different years to select!

Yes, I think there's a bug when using Internet Explorer. I've asked our development team to look at it, but as they're all volunteers I don't know when it will be solved.

Another map uploaded this morning, again with thanks to drm567.

It's Sheet 142 (Hereford) Revision B from 1967, so can be found in the usual place. Enjoy!

It doesn't work for me on IE but is fine on Chrome.

Just tried this and the different years show up in Edge but not on IE11. There was also some odd green and black glitching when I zoomed in close to Epping, but that seems to have cleared up.

Bits of the A40 under construction at Monmouth, including the tunnel. The (very short) tunnel route is not shown but the symbols for the portals are in place.

I'm trying to find in what year the OS first published 1" maps with a distinct symbol for dual carriageways. They originally used thicker black edge lines for the purpose. The oldest I've found so far on SABRE Maps is 1960 (in Bristol). This fits with my previous impression that the practice started about then. Has anyone noticed any examples in earlier years?

[Steven]

A month and a bit ago, I said...

Quite a number from 1970 today. They are:

[...]
Sheet 68 (Biggar, Moffat and Sanquhar) Revision B/
Sheet 70 (Jedburgh) Revision B/
Sheet 71 (Alnwick) Revision B/

In the meantime, no-one has actually noticed that these three maps were missing!

Having noticed that, it's now fixed and those maps are now visible. By way of apology, I've also added Sheet 34 (South Skye and Arisaig) Revision A//* from the same year.

[Bryn666]

Excellent, the OSM overlay comes in really handy for Scotland!

New one on the 1960 layer today. Thanks to drm567, it's Sheet 150 (Ipswich) Revision A/.

Now we have that one online, it reveals that the unknown version on the Seventh Series layer is actually Revision A from 1956, so that's been added to the 1956 layer as well as being annotated on the Seventh Series layer.

Spot the difference between those two is challenging! Minor formatting differences on the railwy so far...

There's not huge amounts I don't think - I got the difference between the revisions by the occasional station closure and the usual relabelling of some historic sites rather than huge changes in the obvious network. I am looking forward to see what people find!

New collection for everyone today - some maps from 1971.

They are:
Sheet 4 (Shetland Islands South Mainland) Revision A/
Sheet 45 (Sound of Mull) Revision A//*
Sheet 54 (Stirling) Revision A//*
Sheet 76 (Carlisle) Revision B/*/*
Sheet 82 (Keswick) Revision B/
Sheet 121 (Derby and Leicester) Revision B/*/*
Sheet 138/151 (Fishguard and Pembroke) Revision C/
Sheet 142 (Hereford) Revision B/

There's some serious bits of motorway now appearing - M1, M6, M9, M50 and my personal favourite, A46(M). There's also quite a few more minor changes all over the place on this one, and the first addition on SABRE Maps of an example of a Shetland Islands One-Inch map.

Let us know what you find on this lot!

We've got A648 (Kegworth - Nottingham) visible now that the M1 has been built.

Interestingly, going back to the previous version of Derby and Leicester, I hadn't realised that the A6 dual carriageway from Kegworth north west that is now the A50 (well, the westbound carraigeway) was dualled so early on, before the M1 arrive...

[Steven]

Again with thanks to drm567, we have a new revision of Sheet 159, The Chilterns. It's the A/* revision from 1961, and there's a few changes from the extant A revision from just two years earlier in 1959 - my favourite one being the M4 /A4(M) Maidenhead Bypass shown as under construction, as well as the then-new roundabout for the western terminus at Maidenhead Thicket, now of course the northern terminus of the A404(M). Interestingly, the roundabout at the eastern end is marked as being under construction.

What became junctions 7, 8 and 9a of the M4 are all shown including their sliproads.

Now that's a map!

One more for today - Sheet 68 (Edinburgh) Revision B/* from 1971.

I like the M8 and M9 (and M9 Spur, now M90) appearing to the west of Edinburgh, including the original half-built junctions where both motorways were due to continue rather than the "temporary" meeting at Newbridge. The M8's, of course, has now been put into use but that of the M9 hasn't, and won't.

[rileyrob]

It also shows the temporary terminus for the M9 (just inside the edge of the sheet), where it fed into what was presumably still the A9. The eastern end of the A9 has already been downgraded to B9080, though, and runs right through to the A8 before the airport was expanded. Fascinating, thanks!

[Johnathan404]

It's very odd seeing M9 J1a with three arms of almost-equal length!

[Steven]

It also shows the temporary terminus for the M9 (just inside the edge of the sheet), where it fed into what was presumably still the A9.

Yes, it's marked as A9 within the margin.

After a bit of a break from Seventh Series mapping where I had a change of scenery by doing some Ten Mile Road Maps (and some life, of course...), we have another new map provided by drm567.

It's the 1963 Revision B of the London NW sheet. I really like this one - it has the eastern terminus of the M4 Slough Bypass, the (now M4) Chiswick Flyover, the M1 Aldenham Temporary Terminal and all sorts of other goodies.

With my railway interest hat on, I notice it shows Chesham station as closed (white spot, instead of red) - Chesham station has never closed, nor has it ever been planned to close it. It is still open!
