Ahoy! I would like explained where I can be guided through the technique of creating intersections where both the OWR and the avenue / road / OWR are signalized without it looking all horrible.
I uploaded a NAM 34 tutorial showing how to use these onto youtube (https://www.youtube.com/watch?v=5mQZBMUOuXE).
Bear in mind, you can use them when OWR intersects with road OR avenue. To my knowledge more complex setups involving more than 2 road types are not supported.
