As a GENERAL rule, if the first digit is EVEN, the route is an Interstate Loop, which means it usually goes around a city or urban area and then reconnects to the Interstate again, with an Interstate at both ends.

The standard interstate routes will always have one or two digits (I-5 or I-70) and will appear on a blue-and-red shield. In addition, the EVEN numbers get bigger as you move further NORTH, and the ODD numbers get bigger as you move EAST. EVEN numbered routes run in an east-to-west direction, while ODD numbered routes run south-to-north. The Interstate Numbering System consists of even and odd numbers. Notice that all the interstates are odd-numbered, and they all run in a south-to-north direction. At the bottom of the state is I-10, which runs in a west-to-east direction, through the bottom of the state. Notice that the first interstate you see is I-5, which runs south-to-north through the state.
