We tried many solutions when using Bridge Designer. Some were expensive and some were cheap.
This bridge takes full advantage of the stability of the triangle. But this bridge is expensive and complex. So we chose to build another one based on this.
We make the structure simpler and less expensive. We have designed a bridge that is cheaper and meets the standards. However, the bridge bends a lot when cars pass through it. We want the bridge to have more redundant.
Almost all the sticks were subjected to the force.
