Bridge Construction Set is all about building a bridge that doesn't break, although watching your bridge creation break and plunge a train into the watery depths below can be half the fun. Bridge Construction Set is all about building a bridge that doesn't break, although watching your bridge creation break and plunge a train into the watery depths below can be half the fun. In the Bridge Construction Set you design and build bridges and then stress test them to see how your creations hold up under pressure. If when test vehicles pass over your bridge they make it safely across you know youlve succeeded. If they plummet into the river you know you need to go back to the drawing board. The robust physics deployed in the Bridge Construction Set let you build a wide variety of bridges that can span the river. The 3D graphics allow you to view your bridge from any angle including a first person train view - its like being strapped to the front of the train when your bridge is first tested (if this happened in real life I think we might have engineers checking all their bridges in a simulator).
