This is the way I like to think about it - if you're zoomed way out, a
map of motorways and trunk roads alone is best: plenty of useful
information, but not cluttered.
This philosophy helps justify what you'll find here in the desert south
west. For example, US 93 is pretty much the route one takes from Ely,
through Caliente, to Las Vegas, Nevada. About 260 miles of that is two
lane road. It's marked as highway=trunk not because its some grand
highway along the eastern edge of the state but because it is *the*
highway along the eastern edge of the state.
US 95 through California (about 100 miles) is another example.
Traveling from Las Vegas to Quartszite or Yuma, Arizona state route 95
is a good alternative but if a routing program insisted on Interstates
one would find oneself going through Phoenix or Los Angeles. Kind of a
long way to go.
I should defend both highways by pointing out they don't see much cross
traffic. ;-)
