Planning Your Trip - Defensive Class

Many motorists think they know how to read the numbers, but they may understand only part of the story. Other motorists are confused by the numbers; still others have never really thought about it.

  • PictureEven numbered interstates (1 to 2 digits) are east-west routes. They go from I-10 in the south to I-94 in the north.

  • Odd numbered interstates (1 to 2 digits) are north-south routes. They start with I-5 on the West Coast to I-95 on the East Coast.

  • Planning-Class-Defensive
    3 digit numbered interstate highways connect major highways. If the first digit is an odd number this usually represents a "spur" route heading from an interstate to a destination, such as a city center. An even number means the highway connects to a interstate at both ends (typically a "beltway" or loop).
