What term describes the connection of a freeway to a road or another freeway by a series of ramps?

• A. Interchange
• B. Intersection
• C. Circle
• D. Overpass

Answer: (A)

An interchange is the connection between a freeway and another road or freeway that uses multiple ramps to merge and diverge traffic. This setup provides grade-separated access, so vehicles can switch directions without stopping or crossing traffic at the same level. An intersection is a crossing at the same level where roads meet, which isn’t how freeways are connected. A circle (roundabout) is mainly for slower, local streets and doesn’t describe the typical freeway-to-freeway or freeway-to-road connection. An overpass is just a bridge over another road and doesn’t by itself capture the full network of ramps that link routes.
