this part is marked red on screenshot =============================================== making a new 2 tile wide connection from there to the Highway with Cats Eyes
the blue marked part is the old 1 tile wide road I will leave as it is.
Around andistyr.github.io/wu-map/14821/#2917_2636 (the red dot) I plan to make a Guard Tower, if it's not to close to the existing ones in the south and if I manage to flatten the area properly.
