Your new bridge is moving up and down a lot in the wind! This isn't a big problem under normal conditions, but what if a hurricane were to blow through town? It could cause the bridge to move too much, or even twist so violently that it would snap in half!

Stiffen the deck with an open truss	Stiffen the deck with a solid steel girder	Make the bridge narrower
