I am building a new route and I need a highway overpass that goes over the railroad tracks. I have a main line with 2 and 3 tracks to overpass. I have looked on the DLS and can find many bridges, but they are for going over water mostly. I am using mostly 2 lane roads, but one that would work for 2 and 4 lane roads would be great. I would appriciate any advise on working with overpasses. I am using TS2010EE. Thanks...
