Today we are looking at bridges. We’ve all been over them in a car, and you may have even walked over a bridge. Bridges are a common thing in today’s world. They make transportation faster and easier. But even just a hundred and fifty years bridges were very rare and many people didn’t trust them. They thought they were dangerous and wouldn’t use them. Oh such bridge that caused a lot of controversy was the Brooklyn Bridge which was built in 1869. Let’s start by reading a picture book Twenty One Elephants and Still Standing which was based on a true story. After the Brooklyn Bridge was built, people were afraid to use it. They thought it wouldn’t hold the weight and would crash into the river. B.T. Barnum came up with a way to prove to people that the bridge was safe. (Story for all ages).
