Building Bridges Check for Understanding

Which statement best describes the importance of joints in the roadways of bridges?

• Joints strengthen the roadway to support cars and trucks

• Joints allow the roadway to expand and contract with varying outside temperatures

• Joints allow the roadway to expand and contract as cars put force on the bridge

• Joints allow the bridge to be built in smaller, easier to assemble pieces.

Bridges without joints are safer than bridges with joints because the bridge will not expand and contract.

• True

• False

Which statement best describes why the bridge buckles when there isn’t a joint?

• Temperature causes expansion and contraction of the roadway, which is limited without a joint.

• The metal in the joint is not affected by temperature, so without it bridges buckle

• The material of the roadway doesn’t expand under temperature

• Joints increase the strength of the roadway to prevent the weight of cars and trucks from causing the bridge to buckle.
