Did you know that freeway numbers aren’t random at all, and you can use them to find your way around in an emergency, survival, or bug-out situation?
Here are some rules:
- Odd numbered routes run north and south, higher numbers are east, lower numbers are west.
- Even numbered routes run east to west, higher numbers are north, lower numbers are south
- Three digit highways run only within a single city
- An odd first digit in a three digit highway means the route is a spur route and goes to the city center
- An even first digit in a three digit highway means the rout goes around the city center
- The last two digits of a three digit highway signify it’s origin.
