Also, on the underside there are shaped wooden bars to hold up and support the street. I learned that bridges aren't as easy to make as they look. Bridges take a lot of concentration and ability to make, and firm, strong building materials. If I had a chance to make a better bridge, I might make a better street with more modern technology such as traffic lights. But, it was a fun project.
Bridges are fun.
My name is Aldo. My first bridge, the one I am holding in the picture, can hold two hundred seventy paper clips. It is different from other bridges in the classroom because it is in the shape of a triangle. My second bridge can also hold two hundred seventy paper clips. It is different because it is colorful, and it has guard rails so cars won't fall off the bridge.
