google road names are not 100% reliable and it would be bad form to
presume them correct. they sourced the original names from TIGER like
we did and have applied automagic bots which have screwed some up
the same way we did. i was just looking at a North Road which Google
is rendering as N Road a few minutes ago (i have ground surveyed that
road and North Road is correct).

a road name from TIGER 2012 is a much better choice as it avoids the
potential issues sourcing a name from Google presents. a ground
survey would always be best, of course.
