[Maps] - New layer!

Post by Steven » Mon Apr 17, 2017 18:36

The eagle-eyed amongst you will notice a new layer has appeared today on SABRE Maps. Currently, it only contains a single sheet, but hopefully it will joined by a few others soon.

The 1962 OS Quarter Inch layer can be found under, not surprisingly, the "OS Quarter Inch" menu and consists of Revision B of Sheet 10, North Wales and Lancashire.

Excellent. The c.1961 layer is often several years older in much of the region (~1955 around the Preston area?)

I believe that the "c.1961 layer" may well be the A revision across the board, so the initial set of Fifth Edition Quarter Inch. The North Wales and Lancashire sheet was the first one printed in April 1957, and then the 1962 layer shows the next revision (B, October 1962).

And another one of those single-sheet layers has appeared this morning.

This time it's from 1964, and is the Quarter Inch sheet 7 Firth of Forth, Revision B - showing the brand-new Forth Road Bridge, the approach roads and all sorts of other 1960s goodies. You can easily compare it to the A revision held on the "c.1961" Quarter Inch layer.

Interestingly, it seems to show sections of what became the M80 between Cumbernauld and Denny here. CBRD suggests that J7-9 didn't open until 1974, so the question is, did this open as the A80, and was later upgraded? If so, the map suggests it is a dual carriageway, but what about the hard shoulders?
There is also a temporary terminus with roundabout where the 'M80' meets the A872, and when looking on Google Earth, there is some evidence of an old carriageway alignment here, although no sign of a roundabout.

From the SABRE Wiki: M80 :

The M80 is a motorway in Scotland linking Glasgow with Stirling. It was formerly in two sections, the Stepps Bypass at the southern end, and the Haggs - Stirling section at the northern end, linked by a section of A80. The section of A80 was upgraded to M80, opening late summer 2011
