I'm just trying to model and learn an interchange. I modeled the whole interchange with then when I add Bridge then the terrain appears at the locations where one road meets another. So far I have found only one place where the joint is perfect. I haven't been able to figure out why that happens. Below I have added some screenshots that would be more descriptive of the problem I'm facing.
Thanks for replying. So should I model it using Civil 3D or what? The problem is I don't have exact dimensions as this is a fictitious project. I was just learning. Can I model that in Civil 3D with rough dimensions or not?
