medium size in the middle but this is a long interchange. I just draw what’s inside the map as closely as I can. I do not overdo it. slopes affect size. You Need DLC Mass Transite :). and flat ground for better result . slopes can be demage if ground not flat. I am sure,Turbine is the best for traffic flow rather than the other model interchange. and you can modified to ground lv using move it and fine road tool mod. select square in move it mod and lower it to the ground by -12m ( demolish all national road there if you want to modified ). always sorry everyone,for my bad english 🙂 i dont have time using google translate help
