Placing highways intersections

[ScarcticCG 3]

I need help quite badly on making two of my highways cross over.

Basicly I have two ground level highways that meet two avenues in a cross formation. In other words I have a cross shape made up of avenues, with two of them converted in to ground level highways.

The problem is that I want the two avenues to be converted to highways to make a cross of highways. I thought that to do this, you could place a cloverleaf, but it wont allow me to place this (This is after trying coverting the two avenues to highways and removing the "middle" piece that connects the two roads)

I know that this is probably basic stuff, but I don't know haw to do it. Its critical that these two cross over and that sims can go in any direction from them (streight on, left or right)

I know how to place T-intersections and the lie, but this one has me stumped.

Cloverleaf interchanges take up a lot of space so maybe you need to demolish buildings and roads around it. If it doesn't work, could you post a picture, please?

I found the problem! Turns out that it was being VERY picky about the specific location of a neighboring road. I had to completely remove an entire neighborhood because the way it wanted my road was really awkward. Still, better that the entire regions traffic be able to get through smoothly than have 1 neighborhood. Thanks for your help!
