Answer:

Small abutment

Answer 2

In case of a long bridge the structures provided in between two abutments are known as small abutment.

• A bridge is a building that crosses a chasm, like a river, valley, or road.
• A bridge must have support on both sides in order to span the gap.
• A bridge abutment is a name for each auxiliary building on either side.
• Abutments serve to support the bridge by bearing both their own weight and that of passing vehicles and people.
• Abutments also serve as a wall to maintain the embankment of the roads that approach the bridge from both ends.
• The bridge abutment is a long wall with a foundation at the bottom that securely transfers the weight of the bridge to the ground or rock underneath it.
• The chair-like top portion of the bridge abutment links to the bridge superstructure (the bridge deck and the girders).
• Between the two abutments, additional buildings known as piers are built to support a long bridge.
• Piers do not need to support the earth behind them in order to sustain the bridge.
