U-Turn Interchange

Sometimes you are just missing the space to build a full-blown interchange, but just in one direction. The other one though has plenty of space. The U-Turn Interchange was just made for such a situation.


Advantages:
- High capacity
- Smooth changes of elevation
- Doesn't need a square space to be build

Disadvantages:
- Quite long footprint
- Has weaving, though it doesn't impede traffic that much
- Is expansive
