A highway is a main road people use to travel between different public places. Highways connect cities, towns, and villages. Sometimes, drivers pay money to use the highway, and sometimes highways are free. Highways can go over water, across bridges, and through tunnels. Highways can also go up, down, or under mountains. Some highways have homes or businesses on them. Other highways don't have any buildings on them.
