Upsidedown Stack Interchange
Another stack interchange, this time upside down, with the left turns running underneath the highways underground. One of the interesting things about building the interchange this way is that I was able to tighten the semi-directional turns, and make the angles and grades even smoother, since I didn’t have to deal with pillars. The inclination is never more than half the standard maximum, and even smoother at the highway connections or through the curves. Also, I kept the clearances to 9m to further reduce the slopes. This should basically have the highest possible capacity of an interchange.
Dimensions: 50 blocks from exit to entry in all directions
Heights: 9m to -18m.
Construction Cost: $55,740
I hope you like it.
Also, I created a stack interchange for elevated highways.
