My attempt at a 5-way interchange. It has gone over many different designs.

[PMoore97 83]

Here are some others that I have made...

[PMoore97 83]

Okay! After many attempts and different designs for a 5-way interchange, here is my final product! Taken at different angles.

[Leathershoes&corn 829]

I like interchange too.

[Fargo 553]

I found this on my desktop, taken three summers ago, the last time I had any time to play. I cannot remember if the design was original. I removed the hill that the tunnel runs through with Terraformer.

Diamond interchange expansion

[Indiana Joe 1,750]

Clover-stack in a clearing in the rainforest, for the prefab region I'm doing with Lucario's Humacao.  The north side is the beginning of a pre-made bypass around whatever big city you'd like to build there.

 

 

 

Next challenge is to figure out how to do the T- or Y-interchange with the blue arrow here...there's a bridge to worry about too...

Interchange rebuild to support 6 through lanes

I know I could have just used the median but this was more fun.

 

...But that's what I did with this one

[Christian_Knight78 44]

Here's some of my freeway work with the NAM and RHW mod applied to the basic ground or elevated Freeway (I'm still working figuring out how to build from the RHW mod tiles...) in my capital - Corruscant. In Bree, immediately north of Corruscant. I included a Freight railway "Y." In Qo'nos, immediately NE of Corruscant, I have included a Freight  "Y" railway interchange along with a Freeway "Y." Way out to the ESE of Corruscant, in the mountains of Anchorhead, I pulled off an orthogonal interchange.

Trumpet-like interchange

EDIT

+2 others. Not as impressive/unique but can show anyway

These 3 new interchanges are all on the same new highway

...And ready to support development

Just finishing up work on two suburban interchanges that are located in the Lake Eagan Metropolitan Area.

New design standard

Edit: with traffic and development

[Flann 1,709]

[clonedclone87 95]

This is the northernmost terminus of PR-75 located just to the south of Lake Eagan City's CBD.

Here's how that one went with the bridge.

 

Next is a 4-way with one diagonal route, which is baffling me pretty hard.

The monstrosity...it's complete!

Excellent use of the MHO short L0-L1 transitions! I always forget about those, but they are super great in tight, compact spaces!

^{You might be missing a transition in the bottom right though !}

Taking a break from the Kingdom of Rota and keeping my DOT skills up-to-date! These are my take on re-routing the proposed freeway PR-53 segment in the southeastern part of Puerto Rico, in my brand new region of Guayama!

@Indiana Joe Looks awesome! But sorry I spotted a issue with the SB- you need a lane ending transition before the other ramp merges in.

Some interchanges near the urban-rural transition area of my region:

[Lucario Boricua 7,029]

More freeway stuff, this time a trumpet interchange with just about all the doable transition lanes in the merge and diverge areas. This corresponds to the possible build of the PR-53 and PR-54 interchange just west of the downtown area of Guayama:

Getting back into it. I don't think I've ever actually finished building a Y-type before without abandoning it and turning it into a trumpet instead. They used to always be either squar-y and slow looking with the 90° turns or they turned so huge there was no arguable point in building it that way in the first place anymore when a trumpet is technically advantageous to Y-type designs in several ways, of which the most important one in reality would often be cost. Trumpets only need one bridge structure.

This one...

 

... kiiiiinda pleases me by making some pretty hard use of the RHW's increased stability. It shares some reminiscence of a "pear", the three-way variant of a turbine, but it is indeed a "T",  there being three vertical stages and two bridges.

I'm not huge on the southbound-to-eastbound ramp because that's what I meant with "squar-y". It can't swing any further out in this current state as that would force the other ramp to swing further as well, making for another pretty sharp turn there. I'm considering a redesign where the S-E ramp hops over the 90° bend in the E-N ramp. This would let it swing out a little further and come in a little smoother with a longer run at fractional angle to make the turn it makes look more continuous with fewer straights.

[Haljackey 17,326]

Very nice- I do like the design of that Y interchange and trumpet!

 

This UDI video contains a number of interchanges I've been showing here recently. It completes a major highway network from the main city all the way to the region border with SimNation.

 

 

[Lost Realist 762]

Thanks for the kind words, not coming from anyone when it comes to interchanges.

It ended up getting a redesign already:

 

 

It kind of is a "pear" now. The tunnel's obviously not very realistic and cheating a little but that is one smooth ramp I got out of it. Who would have even thought of an interchange like this in SimCity 4 15 years ago, I mean seriously? I know there's a broken tile.

Went ahead and got a little creative around it already, since this is going to remain the final design of this interchange.

That's a very beautiful interchange.

The overpass that carries the south-to-east ramp across the east-to-north one didn't override properly, the "airbourne" tile remains RHW-2; I presume it's just a tile too short to gain stability. I could have gotten that tile from somewhere but then the ramp would have lost some smoothness and I decided to stick with this for now. As far as the game mechanics are concerned this interchange will not be used by actual Sims either way just because of its position relative to the action on that city tile and with some tactical MMPs, the little snag all but vanishes... The FLEX-interchange piece that merges that ramp into the through highway by the way did something seriously amazing to the slope over there. That's L2 to L0 in fewer than 10 tiles using two FLEX-pieces and I didn't even have to hide any unseemly bumps behind Norway Maples. That was the most surprising experience building this one for me I'd have to say.

And many thanks you guys for the compliments.

I just blew 100,000 simoleons, half this city's budget, experimenting with an urban interchange for an expressway... I ended up with a common cloverleaf.

[Lost Realist 762]

Wait, what!? Where do those intersection pieces come from? What did I miss?

I may be wrong but it could be the new OWR ramps (Real Expressway) with NAM 38.  It also could just be slip lanes which you can do by dragging a combo of OWR plus road, although I have never seen two slip lanes converge into road like that before so I too am interested to see how @Edvarz accomplished this.
