Phineas T. Barnum marched his elephants across the Brooklyn Bridge to prove the bridge was safe. Since the bridge held for 21 elephants, now everyone wants to take the bridge. The city needs to build another bridge to hold all the people who want to cross the river. The river is wider where the new bridge will go, so it needs to be longer than the first bridge.

The student's challenge is to design and build a bridge according to directions and then make the bridge longer to cross the wide river.
