A community dedicated to SimCity 4 and all city-building games. (About Simtropolis)
A three level interchange to link two freeways with a roundabout (made with freeways parts). Once installed, like any mod, you can find it with the name "Echangeur trois niveaux" (in French).
It helps fluidifize traffic with a reduced obstruction of the ground, tested and approved in a 300k inhabitants city.
(I just saw that a nearly identical interchange was posted yesterday, I didn't copied it, mine was created like two weeks ago)
