Sunken Rural Roundabout Interchange

A smooth way to connect up a 3-lane and a 1-lane highway without impeding their traffic that much. You will be able to get this one out of the ground by raising it up one elevation step. Some of the ramps on the ground will turn into bridges then.

You might be asking yourself why the ramps to the 3-lane highway are bridges: It just doesnt look as glitchy as if they were on the ground.


Advantages:
- Smooth elevation changes
- No impediment to traffic on both highways
- Can be "unsunk"

Disadvantages:
- Weaving in the roundabout
