found just another example:
if i look at www.streetmap.co.uk,
Westminster Bridge in London seems to be a part of the A302

traditional maps show overland streets in lanrge scale maps
and local streets in low scale maps

as you mention "private jets"
ICAO Aeronautical Charts are just topographical maps with
an additional layer that shows navigation and airport informations,
becons, no flight zones etc.

usually you get them (sometimes color coded)
Bundestraßen and Landesstraße are usually drawn in yellow on
german maps, Autobahn in as 2 orange lines with red sides

they have a box with the number on the line and the street name
written on the line

On small scale maps it looks like:

           +-----------+
-----------|           |-------------------------
           |   B 26    |  Wilhelm Leuschner Str.
-----------|           |-------------------------
           +-----------+


On french maps (Michelin), they code main roades in red,
regional roars in yellow and draw the road nr in a box beside
the road
