Different designs work better for certain spots. Some bridges need to be long and strong, while others just need a simple design.

Question 12

What happens if a bridge is too old?

Accepted Answer

Old bridges can be dangerous if not taken care of, so engineers check and sometimes replace or repair them to make sure they are safe.

Question 13

How are bridges built over big rivers?
