I was trying to solve the traffic around the big arterial on the bottom so I was trying to clean up the preset cloverleaf area. All I did was change the highway entrance from a straight roundabout to more of a funnel since I noticed some cars were using it to do a roundabout and enter the other highway, but then suddenly traffic backed up all the way to the northern farm area. IDK what I did wrong, any tips to solve this issue? Aside from the mods in the screenshot, I'm using the Realistic Population and Unlimited Resources mod.
