Is anyone aware of a complete list of all and B roads starts and

eg A34 Southampton-Manchester

The A34 traditionally ended at Winchester, then carried on to
Southampton as A33.

But see: http://www.cbrd.co.uk/index.shtml

And the other end of the A34 is Salford, not Manchester, according to the
Ordnance Survey. (There's a big chunk missing in the middle too, where it
has been replaced by M40/M42.)

And the A34 has even been redesignated north of Oxford: at one time it
deviated off the present route at Peartree roundabout and went up through
Woodstock to Straford-upon-Avon and beyond, whereas that road has now been
renumbered the A44 and the present A34 was once the A421.
