A2021 Figure 8 Interchange

This is a Figure 8 Interchange. It's a 'Free-Flow Service Interchange', connecting a highway to a regular road network.

Please note that traffic coming off of the highway can head into both north and south directions, while traffic coming from either north or south can only turn onto the first highway they encounter (directions based on screenshot #1). I therefore advise to have a roundabout or other possibility for traffic to make a u-turn at the north and south exits.

The road markings you see in the screenshot are saved into the asset. If you want those markings to be visible in your game, you'll need to subscribe to the Intersection Marking Tool.

Several TM:PE options are saved into this asset as well. If you want those options availlable in your game you need to subscribe to the Traffic Manager mod.

- To fully enjoy this interchange you need to subscribe to a couple of mods. These mods do not affect your games performance. They only add extra very handy tools to your game.

Because '3-lane highways' are the most commonly used highway type on maps, I've created this interchange to be connected (the highway ends on the interchange) to these 3-lane highways. The 4th lane on the 4-lane highways are used as exit and entry lanes.

Enjoy!
