A1 - Tillman

The object of this bridge is to provide a sturdy, reliable pathway over the river. This bridge has the upper section of beams to provide additional support. There is also a strengthened section in the middle. This section provides extra rigidity to the structure when the load is in the middle of the bridge.

Over the course of designing the bridge, the upper supports were added. These were added to reduce sagging and provide the bridge with more sturdiness.

This bridge would cost exactly $594,995.40. To reduce cost, beams that don't undergo as much stress could be substituted with hollow pipes. In addition, certain, less-necessary sections of the upper supports could possibly be removed entirely.

While designing this bridge I learned that designing a bridge takes patience and careful testing. Also, I learned that cost is important but very difficult to manage. The best way to keep the bridge's cost low is to be smart with the materials that are used and place less reinforced material in areas where it isn't needed as much.
