Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the primary structural role?Support vertical and lateral loads from bridge superstructure and traffic
2. What is the secondary structural role?Act as retaining walls for approach embankments, resisting lateral earth pressure
3. What is an abutment on a bridge?An abutment is like a strong hand at the end of a bridge that holds up the bridge and keeps it steady. It transfers the weight of the bridge and cars to the ground and stops the bridge from moving sideways.
4. Why do abutments need to be strong?They must be strong because they support all the weight of the bridge and keep it from sliding or falling, especially when wind, earthquakes, or cars brake hard.

Substructure: The load-bearing elements of a structure below the superstructure, including foundations and abutments.
Superstructure: The part of a bridge or dam that is above the substructure, including the deck, girders, and abutment-supported spans.
Lateral Earth Pressure: The force exerted by soil or rock against a retaining structure like an abutment.
Geotechnical Engineering: The branch of engineering concerned with the behavior of earth materials and their use in structures.
