An interesting way to tackle the traffic cross over problems with most intersections. Well done.

@Vii, it's true that the sharp corners will slow traffic, but not substantially. Even with extremely high traffic, I haven't seen this interchange cause traffic issues. Most traffic bottlenecks I've seen during my current playthrough, using this interchange, stemmed from other factors - poorly designed downstream interchanges, highway entrance/exits, industry/commercial density, etc.

The potato video I have provided is at speed 1, it should provide a basic understanding on where potential problem spots originate. There's also the option of upgrading the off ramps into highways to increase vehicle throughput at the intersection.

Absolutely beautiful interchange, but don't the hard turns slow down traffic substantially?
