I'm playing SimCity 4 Deluxe (on Steam) and am trying to build a bridge (or something to the same effect) for a railroad to cross a ground highway. How can I achieve this?

Here a screenshot of my situation:

Without mods, i'm not sure you can. – Ender Dec 25 '12 at 16:33

The only way to do that is through the underground crossover exploit. You will never be able to achieve that in the normal way. Here is what I mean!!enter image description here

As you can see if both the segments are underground there is an exploit/bug which allows such crossovers to exist.

Oh man! That's very ugly! :-) – Luc M Mar 24 '13 at 19:53

Highways can pass OVER roads, but roads my not naturally pass over highways. For the road to pass over the highway, the road will need to be built first.

Does the same hold true for railroads though? – Nick T Dec 25 '12 at 22:33
I think so. It's been a long time since I last did this. With railroad in Simcity 4, you can always transition from surface to underground, so you can just go under a highway if you really want to cross it and then transition back to surface. It is expensive, but anything dealing with the highway is going to be expensive. – StarPilot Dec 25 '12 at 22:37

You have to build the rail first then elevated highway over it. You also must leave lots of space to make the ground to elevated highway transition.
