Very nice interchange, AIX and Cartographer29

New interchange for the city highway (Sorry for very bad quality )

I'm still working on the neighborhood.

Oh very nice!

An intersection with interchange elements I'm tinkering with. The hilly surroundings don't make it easy

Cartographer29: Looks like someone followed my Dumbbell Interchange Guide

Nope, I did it myself. Although yes, the results are the same. Great minds think alike.

As much as I despise the design for it's incredible ability to cause terrible weaving, everything has a real-world counterpart ... http://goo.gl/maps/iQ9Xi

[Cob92 360]

Not to mention that nearly every urban interchange in Texas has that kind of weaving setup. The only flaw with that one is the very short distance available for drivers to weave in and out of the ramp lanes. That could potentially lead to accidents due to drivers rushing to enter the main lanes (plus curved ramps like that don't exactly help you accelerate to freeway speeds).

A Double Crossover Merging Interchange.

This is as compact as I could make it using 'wide curves'. Of course to save on the one tile at the ends of the 'wide curves' you must place them before the joining transitions etc. This would not fit on a small map. I actually think that not saving on the one tile each end of the 'wide curves' and stretching it out a bit might look even better. Im going to try to create an 'upside down' one next ie elevate the ground pieces and ground the elevated pieces.

I'd classify it as a full grade-separated diverging diamond interchange

A Double Crossover Merging Interchange.

Nice work. I feel like playing in my sandbox now!

Got the idea from http://en.wikipedia....ing_Interchange... It says that "It is not known whether any such interchanges have been constructed." maybe you know of a real life example?

There's also this bad boy:

There's a couple free-flowing diverging interchange tutorials over at the RHW interchange guide: https://www.sc4devotion.com/forums/index.php?topic=14074.msg405104#msg405104

I'd love to add yours if you're interested in making a tutorial!

[Bipin 3,402]

I built something like that without even knowing it!

It started as a simple highway bend. But I wanted to add another highway. Well it's simple but I'm still in training. I think I'm getting better and better

[SAVAGExPHOENIX 955]

This looks a lot like the President George Bush Turnpike & TX114 interchange in Irving, TX. I used to drive that when visiting my parents near DFW. I like it.

A Double Crossover Merging Interchange with elevated highway.

EDIT: Thankyou for the like... however I am going to redo this interchange as my intention was always to make a high capacity interchange using only 'wide angle curves' and as you may notice the sections of RHW4 that pass under the elevated RHW4 do not use the 'wide curves'... this means stretching the interchange out a little to get both curves to fit on either side...

A couple of examples of Roundabout (Service) Interchanges with elevated highway and free flowing avenues.

Very nice interchange everyone .

SimRicard, you should avoid double post .

My newest interchange, I don't know, what I can call it.

[nathanthemayor 1,261]

Nice interchanges everyone.

Here's a new one, and nope, for those of you who are wondering, it's not in The UC, but my offical Sandbox region.

Just out of curiosity, what would this interchange be classified as?

This is one of the variants of the cloverstack interchanges--a fairly conservative one, I might add (it has the flyover ramps entering through the outer lanes of the freeway--the semidirectional arrangement).

[AIX 270]

This one quickly spun out of control in terms of size and complexity, but I like it. The west-east freeway (the larger one) has local access/high speed lanes.

[SimRichard 10]

I was going to build the interchange (Diverging Windmill [system] Interchange) as shown in the diagram Haljackey posted, however I decided to try something a little more complex...

A Two-level Turbine (System) Interchange.

Looks good but with this design I ran into this problem...

So had to change the design slightly... I tried a few different things, you may notice that picture 1 (top-right) also shows a slightly more compact 'spiral' using curved transition ramps... (I prefer that this part of the design)

Which picture do you think shows the best design for the highway exits?

[MandelSoft 2,769]

Well, I would bring down the whole ramp and like it up as you do for the other two ramps.

[SimRichard 10]

Thanks for the idea... the thing is, the left arm of the exit ramp must elevate at some point, I could do this by elevating it just before entry to the elevated highway... however me being me I like to keep things like this symetrical and if I did this on the adjacent corners I would run into the same problem... I will give it a go though, at the sacrifice of symetry, and see what it looks like... will post picture soon.

How about this? I have made the whole interchange more compact also...

[Haljackey 17,268]

ah that's much better.

Kinda reminds me of a similar design I made:

[mapboy 106]

Here's my latest unique interchange:

Sorry that the image is a bit small...

[SimRichard 10]

Built another of the same (Two-level Turbine [system] Interchange) this time using wider curves on the inside and on the outer most exits/entrances... also, I think this is slightly more acurate to the diagram for design.

Its a shame there are no wide curves for elevated highway, some more elevated exits/entrances would also be nice

  Edited November 2, 2012 by SimRichard  

[MandelSoft 2,769]

Yes, we know that such things would be nice, but because it requires full 3D models, the modeling on that front is a little difficult. But who knows...

Anyway, the current design looks pretty OK

[NorthStarDC4M 8]

Well.... I don't know about wide turns... but I've been playing with older urban style interchanges... one example:

From my Van Alden Parkway project... really should do a CJ about it.
