The only known use of the A748 number is for the road which ran from the A75 at Dunragit to the A715 (now the B7084). It was originally classified as the B736, and is now unclassified. The road itself is a short route, less than a mile long, and apart from passing Dunragit Station serves little purpose as an A road. It is presumed that it became unclassified when the A75 Dunragit bypass opened.
Curiously, the A748 is still marked as the B736 on the 1932 10 mile map; though it is marked on the 1936 edition. However, whilst this has led to speculation that the route was given the number later, and that there is therefore an as yet unfound earlier incarnation of the A748, no such route has yet been identified. Logic would dictate that any earlier route would have been numbered in sequence with its neighbours, and whilst the A749 is on the edge of Glasgow, the A747 is just a few miles from the identified A748 in Galloway. This leads to the possible conclusion that the 1932 map had not been updated for this very short route, and as other errors have also been identified this is at least plausible.
