I built this interchange in order to bound my futur industrial area "Holzstein" (literaly "woodstone" in german), "Mariville", "Chalon sur pin" (residential areas) and southeast Corbois to the "A1"
It look like quite dangerous but it's actualy one of the safest (with roudabouts) and most efficient design for highway entries

It took me roughly 15h to redo this interchage sow please diamond if you like, you will be able to explore that structure in the next vertion of Novock, the link if you want to checkout :https://www.planetminecraft.com/project/novock-a-beautiful-and-realistic-city-in-minecraft/
