It didn't work very well, at least in the situation I tried it. I have a large Industrial area and Residential with the original Highway between them. I did play with it and "upgraded" using the Ramp road (80mph) on the elevated inner roundabout and 6-lane on the outter roundabout. It still ties up too much traffic starting at the ramps from the Highway to this intersection.

My pop is 28k and maybe I'm at the point I need to consider a full highway going through my city instead of the 6-lane heavy road.

I do think this is a nice design but would consider it as for moderate traffic and not heavy traffic.

This is pretty nice. A couple suggestions. Make the raised roundabout highway rather than one way. I understand having a oneway roundabout on the ground so you can place buildings. I also don't love the 90 degree turns coming off/on the ramps.. I might try playing with the design :). Thanks!

I really love this one and I used in my city a lot, connecting the structure one to another so that every main street has it's own intersection.
@⊁ĴōｿﾞŚťĪ⊄Ӄ⊀: I would like to ask you, if you have time, to create a similar intersection but with the highway on the same level (without going down). I tried to modify yours and I failed... :/
Thank you, tAlpA

This is really a GREAT intersection, handles massive amounts of traffic! Thank you!

Nice work, tried a bunch of these intersection ones, this one is one of the good ones!

Really impressive. Going to test it ingame right now! Thanks for making such things.

This is amazing! i use it with 2 large roundabouts to handle some serious traffic. TY!

This is excellent - I use it all over the place.

great job! =)

@⊁ĴōｿﾞŚťĪ⊄Ӄ⊀ Thanks for the answer, i was trying that ... :)
this is great stuff, thx a lot !

@ChiChi Thats just for the Building zones / Deco stuff) You can build houses along this roads ;-)

i don't get the purpose of the little roundabout on the ground with 2 roads not "finished/connected"

thanks !!

great job !

Ah okay, ty :)

@LightOfDivine ツ oneway roads into oneway roads dont produce traffic lights.

How do you reduce number of traffic lights? ;o
