Papa and Nana’s boat had to go under many bridges on their trip. There were a lot of bridges that were too low for them to get under. These bridges had to move so the boat could get through. Fuzzy didn’t know there were so many kinds of bridges that could open and that they had different names.
This one is called a lift bridge. Part of the bridge, called a span, rises straight up so the boat can get under.

This is a bascule bridge. Bascule is a French word for seesaw and balance. A bascule bridge lifts up on one side to make an opening for the boat to go through.
This is a swing bridge. The movable part of the bridge pivots in the center, and turns horizontally making an opening for the boat to get through.
Fuzzy never thought he would learn so much on a trip!
