Finally, I made two own version of 2L Shuto through assets editor and can made something like ARTFX and takaoila.
I really don't know how to use indivisible lane and no function Elevated lol.

How to use the indivisible lane ?
I want to do something like the screenshots of ARTFX and takaoila.
Use fine road anachy to place the indivisible lane and no function Elevated together?

I can't find the no function Elevated in game but can find it in asset editor.
I don't know why.

Dear author,
Hello, I really like the "SHUTO expressway" asset you made, but I was missing when loading the Pazu asset. Do you know why? In addition, how to draw the diversion line of high-speed fork road?
親愛なる作者、
すみません、あなたが作った「SHUTO Expressity」の資産が大好きですが、PAZUの資産を積み込む時に現れた状況はご存知ですか？また、高速分岐点の路面の導流線はどのように描かれていますか？

首都高のトンネルが欲しいです！

Looks great ~ Thanks for your hard work...

Just tried these out for the first time and these extensions are really good, that invisible road is very handy and makes these turns much more realistic. Great job Tokachi269. See them in action here: https://psteamcommunity.yuanyoumao.com/sharedfiles/filedetails/?id=1654026362

Did some observation and usage on 首都高 in google earth, thanks for your reply!

No problem, you are doing amazing work!

@ARTFX
Yes, I thought I needed it, I thought that I made it when I got a request. Probably it is possible(*^^*) However, I think that it will be a mesh fence because can not use glass in the network. Please wait!

Thanks, this will come in handy for making some more realistic turns and stuff. I have a request: you think you could make a section like this where the expressway becomes wider for just a bit but the lanes keep going straight? I think these might be emergency stop points or something similar. I see them a lot all across the expressway network, so would be nice to have these included.
Example 1: https://goo.gl/maps/6g457AAVSqK2
Example 2: https://goo.gl/maps/BXpdQpWTo1s

Also the barriers look different in these sections of the expressway, one has glass in it and the other one looks more like a mesh fence. Would be nice to see this different barrier style as well, but that is less important than the wider sections.

@Schokolade
I am glad to say so! Tell me if there are other shuto assets you need!

Thanks for outstanding work!
Especially, no function Elevated and invisible lane are very helpful

oh it's a while, my whole hw network in my city is Shuto

@takaoila
SHUTO expressway was designed with two lanes at first, and thereafter it may be operated as one lane due to frequent changes in speed limit and accidents. In order to maximize the turning radius it will go through out-in-out. It is for reproducing it. But actually it's hard to use this lol

I subscribed this asset, and wondering what is the real purpose of that no function elevated road?
