Odd numbers run north-south increasing from west to east (Interstate 5 Belingham, WA to San Diego, CA; Inerstate 95 Houlton, ME to Miami, FL). If three digits are used and the first digit is even then the interstate circles (not always completely) around a metropolitan area, if the first digit is odd it is an access into the metropolitian area.
