Research Summary
During this project, I realized that the only way to get it done, was to first get a working design no matter the cost, and then find a way to slim the price to meet the budget. And of course the only way to get a working model was trial and error. After many trials, and many, many errors (and a few bugs and glitches) I found a working model, but it was $452,500 which is 52,501 over budget. So i did some more trials of switching certain beams to hollow tubes since they are cheaper, and seeing which beams failed under the pressure, and the ones that didn't fail stayed as hollow tubes.
Final design
Sorry for the low quality of the price. In case you can't read it, it says $368,545.61
Material JustificationI picked the materials I did because the carbon steel beams provided the strength needed to support the bridge and the weight of the truck it would be carrying. I used hollow tubes where the bridge needed a little extra strength, but not a whole lot so as to save on cost.

Conclusion questions
1. Depending on the stress applied, I would either make a member a hollow tube or a solid bar. I used solid bars for the most durability and strength where there was the most stress, like the bottom to reinforce the concrete decking, and along the top frame to add support to hold it together. Hollow tubes were applied where reinforcement was needed, but not much, so as to save money the hollow tubes were used. On the design, the lighter grey represents hollow tubes and the darker grey is solid bars.
2. Compression and Tension can work together to create a stronger bridge and a weaker one. A weaker bridge can be created by having 2 tension forces on opposite sides to completely pull the bridge apart. Where as 1 compression and 1 tension force can combine to make a stationary beam (I have no clue what i am talking about)
