Question

list 4 types of interchanges found on a freeway.

Explanation:

Freeway interchanges are designed to manage traffic flow between roads. Four common types are defined by their structure and traffic handling:

1. Diamond interchange: Uses four ramps to connect a freeway to a crossroad, with at-grade intersections on the crossroad.
2. Cloverleaf interchange: Features loop ramps for left turns, allowing full access between two freeways without stopping.
3. Trumpet interchange: Connects a freeway to a single road (often a parkway or highway) with a trumpet-shaped ramp layout.
4. Stack interchange: Uses multiple levels of overpasses/underpasses to separate all turning movements, ideal for high-traffic areas.

Answer:

1. Diamond Interchange
2. Cloverleaf Interchange
