My bridge design is shaped in this form because I wanted to create a strong bridge with many triangles. My bridge contains nothing but triangles of which are different shape and size.

My bridge changed during design by adding more triangles of different shape. I was initially thinking of a bridge that are basically made out of triangles that were of same size and shape, but I realized that it was better to add triangles of different shape and size so I added them to the design. 

The cost of this bridge is estimated to be $433,877.05. I think that this cost could be cut down to about $400,000 with further time and knowledge.

From designing this bridge, I learned that a bridge that uses triangles in its structure is strong. Not only that, but the more variety of triangles the bridge has, it seems like the bridge is stronger and can withstand more weight. For further improvements, I would like to make the bridge more strong and stable by adding more triangles into the structure.
