Pinwheel Interchange

Description
The design for this interchange came to me in a dream. It's magic. As far as I know, this isn't an already used interchange design, and how cool is that. Try a CS original interchange.

So the idea here is that the through lanes winds around the left turns, instead of the other way around. It turns out to be a lot easier to build a four-way interchange like that, so I could build a nice smooth interchange that's only 29x29 blocks, and leave plenty of room for traffic to merge. The highway is trifurcated when it enters the interchange, and through traffic is moved across traffic turning left from the opposing lane, to merge on the near side of traffic entering from the left. It's sort of a combination of two of my favorite designs, a stack and a full diamond.

It's pretty effective for anyplace where through traffic isn't overwhelming predominant. I hope you like it.

Dimensions: 29 blocks exit to entry all directions
Heights: 9m
Construction Cost: $20,720
Upkeep Cost: $228/week

From a road geek this is brilliantly designed. No clue if it exists in real life but it vaguely reminds me of a pinavia interchange. Everything is just very well spaced and looks like it handles heavy traffic well. Very well done Employee 432. Cheers :steamhappy:

Thank you for this! It saved my city from a huge traffic problem!

If we were able to setup more precise turning lanes, this would be perfect for even heavier traffic. It does work great for lighter traffic loads however and has pretty good flow when theres not always a car stopped on the highway trying to turn into another lane. Wonder if the Devs would ever fix that if they knew just how bad it gets on very busy roads.

I know what you mean, trifurcating the highway means that you need plenty of space before the interchange for traffic to switch lanes. I can create another asset with all right hand side exits. Thanks for the input.

I downloaded this and used it in my own city, in two places. The first did ok. But the second one, not so much. My city has about 60,000 so far, half of which live in and around downtown. The interchange connected the elevated downtown loop from the south up to the main east-west highway. Well, most of the jobs are in the east, so I had a lot of traffic coming from the west and south. The main problem i seemed to notice was that though less cars came from the west, they would disperse across all three lanes, and, for some reason, were given priority over the ones coming from the south, so the downtown loop backed up like crazy because no one could get out. I eventually fixed it kinda by letting the loop highway enter onto either side, and it works fine, except for that one spot. So i guess users be warned: it has a hard time handling traffic merging.
