1. What is the primary engineering principle?Grade separation to eliminate direct intersections
2. What is the common materials?Reinforced concrete, steel, pre-stressed concrete
3. Why do cities build overpasses?They help traffic flow smoothly by letting one road go over another, so cars don't have to wait at traffic lights or stop signs.
4. How do engineers make sure an overpass is strong?Engineers use strong materials like reinforced concrete and steel, and they design the shape and height so the bridge can hold all the cars and trucks that will use it.

Grade Separation: A method of constructing transportation routes at different elevations to prevent direct conflicts and improve flow.
Interchange: A complex network of overpasses and ramps designed to connect multiple highways or roads at different levels.
Load Capacity: The maximum weight that a structure, like an overpass, can safely support.
