Trainz

Does anyone know of a road bridge with reasonably long uprights. There is at least one rail bridge like this, but none of the road bridges seems to reach the floor of my valleys. I was hoping to insert a screenshot here, but I have no idea how to create a url to an image on my desktop. I was using a rather nice brick viaduct, but one of my rail lines runs underneath it and then you can see how the poor thing just hovers in mid-air.
