The last pic shows a size comparison as I laid it over agusingnavy's. You can see the result in the editor snapshot and the pic of the 2 interchanges together it's on the left. Since I liked agusingnavy's idea I decided to try cleaning it up and without mods, made a smaller version based on that same design. For example, a few of the earthwork ramp to suspended ramp sections have dark shadows/lines through them and the street lights clip through the lower, outside, raised lanes as you can see in another screenshot. While I like the work done on this one and the idea of it, a few things stood out to me that just did not fit well and appear to be a result of the mods used to make it. I took another look through some mods and found one that actually had all exits on this site here. Unfortunately, I did not notice it lacks the number of connections I wanted and had to improvise and it was in-game instead of the much easier editor. In the screenshot with two interchanges, my first attempt at a 4 highway intersection with each highway exiting to the other 3 is on the right.
