A2021 Three-Level SPUI

This is a Three-Level S.P.U.I. Interchange. It's a 'system interchange', connecting two highways with each other. This design comes close to a Stack Interchange. Though slightly more compact and cheap. This design only has three levels of traffic instead of four. And left-going traffic meets in the middle of the interchange at an intersection with traffic lights (only two steps!!). The roads leading to the intersection are inverted. So only on these roads will traffic drive on the 'wrong side' of the road. The use of TM:PE's lane connector tool is essential in this.

This interchange is made useing NCR and IMT. What you see in the screenshots is what you get after placing it, including the markings on the junctions. The interchange can be placed without the 'Intersection Marking Tool' mod. But without it the markings on the junctions will not be visible.

- Cost: 51.800,-
- Maintenance: 786,-
- Size: 100x100
- Max. height: 12m
- Min. height: -9m
- Lane mathematics are applied for a good traffic flow.
- Lane connections have been applied.
- No clipping lightposts/streetlights (lights going through roads situated above them)

- As always; flatten the entire area the blueprint/template covers.
- Smooth out the terrain after placing.
- Use TM:PE to install a timed traffic light at the intersection (see screenshots).
- 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!


Want to know how 'Lane mathemetics' work and how to use the functions of TM:PE? I recommend watching some of Biffa's traffic fixing video's on Youtube
