Even-numbered two-digit highways generally run in which direction?

• A. North-South
• B. East-West
• C. Diagonal
• D. Circular

Answer: (B)

Even-numbered routes are laid out to run primarily east–west, while odd-numbered routes run north–south. For two-digit highways, this pattern means the number itself signals an east–west orientation. So, the best answer is East-West because the numbering convention uses even numbers to indicate routes that traverse the country from east to west, making that the general direction of these highways.
