Do odd-numbered, 2-digit highways run north-south or east-west?

• A. East-West
• B. North-South
• C. Northeast-Southwest
• D. Circumferential

Answer: (B)

Odd-numbered two-digit highways are designated for north-south travel. This numbering scheme uses parity to indicate direction: odd numbers run vertically (north-south), while even numbers run horizontally (east-west). The system also arranges numbers so that lower odd values sit to the west and higher ones to the east, with even values increasing from south to north. So, when you see a two-digit highway with an odd number, you can expect it to be a north-south route.
