@CreatorofWorlds, I don't have that road that you listed, weird

Just to add below. The linked road is not what is actually needed, but the substitute road that RON uses.

So i got it to work, but it needs this

But i'm unsure is that is the actual road asset since i'm trying to run RON also. So maybe RON substituted some file for the above asset.

I used this trumpet at the base, for both trumpets, I just updated the roads to be highways instead of local roads

Very strange :-(

It's a shame, i really liked what you have done and liked to use this and the other one.

I'm just wondering. Did you originally use some other road to design the layout and then upgraded them to the mass transit road?
If so, and not that it should matter, but perhaps then some info was left in the asset file.
Do you by any chance have some rural roads named like the ones mentioned?

@creatorofWorlds I've added the image of what road was used

Please see the link for the loading order mod

Seems that i'm missing these even though i have all the game dlc's.
Small Rural Highway and Small Rural Highway Elevated

I also have all the dlc's
I'll try looking at the loading order mod report and again and see if there are a more specific indication on why it fails.

@creatorofworlds I've got all the Main DLC's when making this, but its only using default game roads

which dlc roads are needed for this to load?
