i concur with the notion of splitting at state lines. i also think that 
the longer US routes need
to be handled in a similar manner.

i don't think NE2 condensed all the relationships; he hit the I-90 
East/West and I-81 North/South
relations i built in NY, but just altered the names, leaving both 
relations in place.
