Smart Intersection Builder (P&P Updated)

Please report any bugs and/or odd behavior! It could by caused by the new update(s) and I might not know about it.


This mod allows you to place prebuilt intersections and tollbooths onto existing roads without the need to clear the area before. All the colliding roads will be deleted and the edges will be reconnected to the existing road network.
The mod menu appears automatically, there is no button or shortcut.
You can hit the Undo button to remove the last built intersection and restore the road network as was before!

You need Network Anarchy for this mod to work (Don't frorget to enable it)!

If you see error like System.TypeLoadException: Could not load type 'HarmonyLib.Harmony' from assembly 'SmartIntersections' you forgot to subscribe to Harmony 2

Warning! If you are using a local version of Network Anarchy, it must be placed in a folder called 'NetworkAnarchy' so this mod can detect it properly
