Or is this road just a vehicle width?

yup single track - just!

Off the wall idea:

Could you work with a "precast" approach? Cast the tracks in the centre of
the road, including reinforcing mesh, then slide them across by the 2-3'
required to have them in the correct place? That will limit you to perhaps
2-3m cast lengths.

Assuming you were planning on having a digger handy for trenching with the
direct pour approach, the digger might be able to drag and drop them into
the trenches that you cut at the end. Disadvantage: you need to either cast
flat and trench flat so the strips bed well enough, or line the trench with
some sand and be fairly confident of bedding them.

mmm I'd not thought of exactly that approach (i.e. using centre) but
was hoping to avoid digger expenses altogether plus problem of what to
with (almost) perfectly good MOT etc that will be generated - it;s a
perfect sub base for concrete after all !!
also casting in situ will (i hope) ensure "perfect" contact with the
minor undulations of the current surface thus minimising early
cracking/failure etc?

2nd disadvantage - lots of joints.

er not sure... I was kind of expecting them to be needed re expansion?
- and they would be there anyway if I proceed with my rough plan A of
little and often....

Dunno - maybe there are improvements to that silly suggestion that might
lead to something that would work?
