What is an interstate highway?

Interstate highways are part of the Interstate Highway System. Since they pass through multiple states, they create a network of controlled-access highways that allows easier travel and shipping of goods across the country.

The numbering system for interstate highways can be confusing at first, but the system is a logical one—in most cases! An interstate highway is numbered with one or two digits—an odd number indicates a north-south route, whereas an even number indicates an east-west route. If the route number is divisible by five, it’s usually a major coast-to-coast or border-to-border route.
