Bridge project

This is our bridge project. Our bridge is the second best in the class. Have a ratio of 1000lb/g. There is two type of members. One is 75% infill another is 100% infill, I show both of them in the top. They all have a 0.1-inch diameter. I'm so surprised that it holds so many lbs. Our bridge is the lightest bridge and should be the weakest, but it did hold a lot of weight.
