how to make underpass under ground highway?

Recommended Posts

I titled this wrong. Meant to say "how to make underpass under elevated ground highway".

 

I'm trying to recreate ground highways that are raised on hills that then have underpasses under them. This basically.

The game doesn't let me though. You can see I have the incline mod. Made a little hill to raise up the ground highway.

It is here where it freaks out and does everything wrong. When I drag a ground highway across it does this.

When I grad an elevated highway it does this.

Am I doing something wrong or is this a game limitation? I do have NAM installed if that helps any. Is there a mod that will allow me to do this?

This is very interesting.  Which version of NAM do you have?  I believe in NAM 31.1 (not yet released) with all the multi-level RHW this should work.  Best ask in the NAM support forum, here.  The specialists over there will have the best answer.

Ok, I never tried the method you're using so I don't know if you have a bug with NAM or not. Anyway here is a common method to do it:

 

First prepare the terrain. Your ground highway should be exactly 15m below your avenue level (all versions of NAM) or 7.5 m (if you useNAM 31)

Getting the correct elevation is essentially for best cosmetic results. Use hole diggers to make this simple 'provided with NAM 31)

Because you use a slope mod, it will likely try to modify the slope to make it smooth. But in the process, it might lift your grouind highway to an undesired height, so make sure you extend the trench a bit, so the part where avenue overpasses highway doesn't move.

Now drag your highway. Once done, check the height elevation if you want with the TerrainQuery command.

Now go in the road tools, and select avenue puzzle pieces. Press tab button to cycle thru items until you have the avenue over ground highway piece and place it with the help of home/end keys to rotate the piece.

Now select the straight onslope pieces and lay them down...

You're done :)

Here is another image showing what I am trying to do. I made the bridge longer just so I could see if the distance was an issue. The ground highway is level with the bridge as you can see on the left side. The right side I did the same, but dragged a bridge piece to fill the gap. It keeps making a hill and lowering the ground highway. I just want a clean flat transition. The game wont allow me to drag a ground highway to bridge the gap. Also, I am unsure which version of NAM I have. How do I find out? Also, my version didn't come with a hole digger, I downloaded that mod separately to get my highways raised.

 

If a new version recently released, will my game break if I uninstall mine, and install the new version?

That is the opposite of what I am trying to do. Avenue under a ground highway. Except I have my ground highways raised up a square. So instead of lowering the ground like the picture, I raised it instead.

The onslope highway piece is what I needed. Thanks magneto. I didn't realize I had that. -_-

 

This is exactly what I wanted. Thanks again! I guess now the question is is it possible to have on ramps with this config. I got my layout but now I need an onramp!

 

EDIT: Nevermind, I figured out how to do it.

I would have tried a FLUP for that.  You can get avenues under ground highways that way, the only thing is that the cross is invisible because it is underground.
