Yea, I realized that as well. There's even a section of I-80 / I-580
in Berkeley, CA where the directionality of I-80 and I-580 is
opposite... http://goo.gl/maps/XROab (The actual compass direction is
more like N/S on that stretch.)

I don't know if there's a definitive reference for the 'official'
directionality of the freeways?
