In Bridging the Gap, you have to build a bridge to safely get a train from left to right within a limited budget. To do that, you have to place the joints on the wire frame background where you want the members (girders) to join. The joints are free, but the girders cost money. Once you design your bridge, set the train in motion and see if your creation is stable enough to carry the train from one side to the other.
