GD stacked Fwy IC 3 pieces

These are the parts 28-30 of a collection of stacked freeway assets.
They're free placeable.

These are 3 pieces of a 3-part-puzzle.

A picture TUTORIAL is here: https://imgur.com/a/aXe0G

The direction is oriented at the lane arrows of the top level.
On left hand drive maps (LHD) the orientation is inverted.

#1:
A stacked freeway goes underground to prepare to cross over intersect with another stacked freeway.
#2:
A stacked freeway cross over intersects with another stacked freeway that is under ground.
#3:
A stacked freeway comes back to surface after cross over intersecting with another stacked freeway.

GD stacked Fwy-to-underground is a 23 units (184m) long and 8 units (64m) wide 'Intersection' asset that you can place in game and also in the map editor.
GD stacked Fwy crossed is a 14 units (112m) long and 18 units (144m) wide 'Intersection' asset that you can place in game and also in the map editor.
GD stacked underground-to-Fwy is a 23 units (184m) long and 8 units (64m) wide 'Intersection' asset that you can place in game and also in the map editor.

Before you place an item into the game you have to toggle the 'NoPillars' mod to 'Floating'.
Afterwards you can toggle it to 'Pillars' again.

Because actually I didn't find a workaround to make assets like this snapable to each other, you have to place one, attach a piece of highway at top level that is exactly 3

units (24m) long (You need to toggle 'AdvancedRoadAnarchy' on), then attach the next asset.
Afterwards you can easily connect the bottom level of the both assets. Toggle the direction with the road upgrade tool by right-click if necessary.

You can also just place the assets next to each other by eyeball and connect them afterwards with highway segments.

On both ends of the connector are nodes where you can connect ramps.

The street lamp posts of the bottom level stick inside the concrete of the top level, but they don't come through.
As long as there are no custom roads without these lamp posts which is also available in the map editor it's just like that.

*You need the mod 'NoPillars' by some danny:

or
NoPillars ( v1.1 & European Buildings Unlocker compatible ) by BloodyPenguin
http://gtm.steamproxy.vip/sharedfiles/filedetails/?id=463845891

You also need the necessary props:
'gate pillar prop [1-eleveated 3tile width]' by duck clogs -> http://gtm.steamproxy.vip/sharedfiles/filedetails/?id=448910789
'gate pillar prop [1-elevated 4tile width]' by duck clogs -> http://gtm.steamproxy.vip/sharedfiles/filedetails/?id=448912201
'side pillar prop [1-elevated 2tile width]' by duck clogs -> http://gtm.steamproxy.vip/sharedfiles/filedetails/?id=448910008

If you can't place the asset you may flatten that area with the 'Terraform Tool' by rollo:

If that doesn't work for you or you don't want to flatten the area, use the mod 'Configurable slope limiter' by b.fokke:
http://gtm.steamproxy.vip/sharedfiles/filedetails/?id=440635326
Press Left-Shift while trying to place the asset and it should be placeable.

If that also doesn't work for you try it with
'RoadAnarchy' by emf:
http://gtm.steamproxy.vip/sharedfiles/filedetails/?id=418556522
or 'AdvancedRoadAnarchy' by northfacts:
http://gtm.steamproxy.vip/sharedfiles/filedetails/?id=433567230
or the new fork of 'Advanced Road Anarchy' that also replaces 'Fine Road Heights' by japa
-> 'Enhanced Road Heights' by WeWill GrokU:
http://gtm.steamproxy.vip/sharedfiles/filedetails/?id=448434637

'RoadAnarchy' and 'Enhanced Road Heights' are toggled on by default and you can toggle them off/on in game by pressing 'L'.
'AdvancedRoadAnarchy' is toggled off by default and you can toggle it on/off by pressing ALT + 'L' and you get a visual feedback.

I recommend 'AdvancedRoadAnarchy'.
