We’ve already covered Cities: Skylines user’s fixation with road porn, but this masterpiece goes beyond such tawdry titillations.


This is a 6-way, fully-connected overpass interchange, made by Guanlong. It’s available for download in the Steam Workshop, and, I mean, just look at this thing.


It’s the kind of design to make a mathematician (or civic planner) weep like a youth in a butcher’s shop.



If you’re wondering how much work goes into such urban planning perfection, Guanlong says it took “probably around 20 hours maybe even 30” to design and build the interchange.
