"USA Map of Interstates": Understanding Numbering Conventions

The interstate system follows a logical numbering system to help drivers easily navigate the network:

  • East-West Routes: Even-numbered interstates generally run east to west, with lower numbers in the south and higher numbers in the north. For example, I-10 runs across the southern United States, while I-90 traverses the northern part of the country.
  • North-South Routes: Odd-numbered interstates generally run north to south, with lower numbers in the west and higher numbers in the east. I-5 runs along the West Coast, and I-95 hugs the East Coast.
  • Loop and Spur Routes: Three-digit numbers indicate loop or spur routes that connect to a main interstate. The last two digits usually correspond to the parent interstate. For example, I-270 is a loop around I-70. An even first digit indicates a loop or beltway around a city (like I-495 around Washington, D.C.), while an odd first digit indicates a spur route connecting to a major city.
