Good point. I know there are plenty of sections small roads that have
been just cut off and left to their own devices but are there any
large sections of A roads (or motorways) that were bypassed and
disused and just left alone?

Probably the longest stretch I know of: when the M74 opened, the A74
trunk dual carriageway was converted to single carriageway B-road, with
the whole length of the second carriageway being abandoned to nature.
