Viaduct Designer

Are you a good builder of bridges? And do you like trains? If you answered yes twice, then you will love a game Viaduct Designer where you work as a train driver and your task is always transport cargo from one station to second. Problem is, that there is missing a bridge somewhere on the track, so you must always stop the train and start build it. Because of your train is really heavy, the bridge have to be very solid. Can you go through all tracks and deliver cargoes always without damage? Have fun.
