style options sounds good to me...
I think just making the fonts adjustable, without increasing the 
lines for the roads, would be good

In CA, the freeways ("state highways" or "state routes") and major 
roads have green signs, however Google just shows a white oval with 
black numbers.

The state of CA has lots of info on signs here:

Some counties, esp. San Diego, have LOTS of "county roads" which are 
small highways (not freeways). For whatever reason, these have 
different signs than any other roads or freeways.
I don't think it's that important though, but there can be confusion 
as there might be a county road with the same number as a freeway or 
state route.
Again, Google makes no distinction.

Google seems only to distinguish between Interstates (I5, I10) and US 
Highways (101):
