What types of things do bridges help transport?

* People: Bridges allow people to cross rivers, lakes, and other bodies of water. Pedestrians, cyclists, and cars all use bridges to get from one place to another.

* Goods: Bridges also allow goods to be transported from one place to another. Trucks, trains, and ships all use bridges to transport goods.

* Utilities: Bridges can also be used to transport utilities, such as water, gas, and electricity. Pipes and cables are often laid under bridges to transport these utilities.

* Animals: Bridges can also be used to transport animals. For example, cattle drives often use bridges to cross rivers.
