Hi Wilky, thanks for the feedback. I tried the small four-lane road as well, but ultimately choose for this one, because it looks much better. As for the zoning with these 24M roads: When you use the mod 'Zoning Adjuster 1.1.1.' you can adjust the zoning distances from roads, so that the zoning will allign with that of the 16M and 32M size roads.

This is a beautiful interchange, but I'm not sure about the 24m 4-lane road connectors due to the zoning weirdness. I downloaded this asset and swapped it out those two pieces of road for the skinny 4-lane road from Vanilla+ instead (which is actually 16m width).
