more understanding if you please make tutorial video how to build on of ramp. really interesting using your road for interchanges.

@Huntron, I think you should do it, no other "lightweight" road pack like these has them, and you could make it an optional add on pack like this too. But either way, fully up to you!

@Nyrob€€ welp, that's what I get for not actually testing what I make. I have made those pictures without ever unpausing the game, so I did not even realize this could be an issue. For now, you you can use the invisible centered roads, and just make the intersection out of props and other assets. That seems to work. Later I will try to diagnose the problem and see if I can fix it.

@Static I have thought about it, and decided for them to be low priority. SHUTO and Ronyx' Expressways were my main sources of inspiration, and they don't have 5 and 6 lane versions either. So I thought that I shouldn't add them too. Plus extending the set with 5 and 6 lane versions would mean adding 18 more roads, and I (personally) don't like how much roads there are in the set already. But if the demand is large enough, then I guess I should make them.

Would you ever consider making a 5 and 6 lane version of these?

Sorry for my noobness. I've made a similar setup as in your uploaded image but cars are slowing down. When I try to change the length of the transition the borders of one of the centered pieces gets in the way of the transition. Any idea what I'm doing wrong?

Thank you very much for explaining!

In the first image, the setup is done like this: https://i.imgur.com/O3pRkxI.png
All roads besides the vanilla 4 lane one, are centered 2 lane pieces, with the thicker ones being elevated, and thinner ones are the bridge version. Then I just plopped some ploppable asphalt and pavement to make it more clean looking.
Additionally, I used Parallel Road tool to ensure that the 4 lane road is perfectly in the middle and that the 2 centered road pieces are perfectly aligned on the (picture's) vertical axis, but you can achieve similar results with only using Move It.

Thx man, will try and see if I can come up with the same results
Especially your first image is a puzzle for me.

Does it look like that the road ends in the middle of the intersection? If so, you should upgrade the road to the 'elevated' version using Fine Road Tool. Only the elevated segments (as well as slope segments for centered roads) have node models.
If you did that but it still does not work, try to raise the road first with MoveIt, upgrade it, and then lower it back down (using ctrl-z). For some reason, Fine Road Tool sometimes refuses to upgrade the road if it close to ground, and will keep it as the ground model (which differ from the other models in that they have no lights)

Excellent work, would you mind however to explain the transition between YAES and normal roads a bit further. Whatever I did, I didn't manage to let it look properly.
