Certainly the key tertiary roads around this area ARE easy to identify 
on the ground and while small sections could be tagged residential or 
service the majority of the roads are clear 60MPH routes in open 
countryside and are essential 'primary' routes to get from A to B 
without long diversions through M,A & B roads many of which have a 40MPH 
speed limit! As I said ... this is not a case of tagging for the 
routers, but simply identifying the facts on the ground which often are 
clear. These roads to not have primary route reference numbers ... but 
they are a key part of vehicle routing.
