Three-digit numbered interstates with an even first digit generally divert through traffic around major cities. What name is given to such a road?

• A. Beltway
• B. Bypass
• C. Outer Belt
• D. Circumferential Highway

Answer: (A)

A beltway is a road that encircles a city to route through traffic away from the urban core. Three-digit interstates that start with an even digit are designed as beltways or loops around a metropolitan area, connecting back to the main highway and forming a circular route. That looping function is what makes beltway the best answer here, since it specifically describes a ring road around a city. A bypass, while it serves to avoid the city center, is usually a single route that cuts around instead of forming an entire circle. The other terms exist in some regions but beltway is the standard, widely used name for this kind of circumferential route.
