Bridge Architect

You are to build a lot of bridges, including road bridges, railroad bridges, pendant bridges, sectional bridges and so on. The rules of X Construction are very similar to the task. You are to build structures that can be used to transport the bridges. You can use a number of elements. The bridge is to be tested after it is finished. Various transports will move by the bridge. It is possible to detect which construction is not capable of bearing the load. They will be highlighted with red. It will be grey or black when low loaded details are involved. The weak spots can be strengthened and a really reliable bridge can be created.
