Thanks for feedback rahtazz! It's in fact quite difficult to make the intersection an even numbered size if you have to Move It while editing. As this intersection is larger than the editing area, I had to move it partially off the area so I could make the furthest parts of the interchange

I do like this interchange, can't wait to see it in action .
However, I find it a little difficult to fit into an existing crossing, because it seems to have odd distances between its legs.
Since I already have two highways laid out, I'd like to clear e.g. a rectangle of 100 by 80 cells near the interscetion and fit the interchange into it, snapping nicely to the existing highways.
This is very easy, if the interchange has dimensions in full cell lengths. This one seems to have dimensions of 79.8 by 99.2, or something. (You know, OCD and all...)
Is there any chance you could adjust this? It'd be so great!
