About This File
I just recently started playing again for the updates since After Dark and wanted to update a previous interchange asset going by the same name that I made. Which, this whole time was missing 2 connections but I never noticed. It's easy enough to fix the other one yourself if you prefer the cheaper and slightly smaller 3-lane version but this 4-lane version should have all highways connected to the others allowing travel from one highway to the other 3.
All ramps are two-lane one-way highways for higher speeds and all road pieces have sound barriers(also easy enough to change to the non-barrier version yourself if you prefer).
I have included a picture with arrows showing the connections(forward, left, right, U-turn) just in case anyone wanted to make sure.
If you get a slope too steep error it's probably because of the turning ramps. Either get a mod or edit it yourself in the editor if you feel it happens too often.
