Show us Your Interchanges!

[Tarkus 6,932]

Thanks, Matias (and everyone who hit "like")!  Speaking of said larger possibilities . . . here's another relatively simple thing that will become possible due to these developments:

And as an added bonus, here's another pretty simple interchange that I've been able to refine, thanks to the additional adjacency stability provided by the ongoing Project 57-Mark IV upgrades to the RHW RUL2 codebase.  Just need to figure out a way to get FTL support added and it'll be perfect.

Rural diamond interchange

Part of a project to upgrade this highway from at-grade to controlled-access.

[Patricius Maximus 236]

Hmm...scrumptious. Just goes to show that an interchange doesn't have to be complex or sprawling for it to be beautiful, elegant, and dare I say interesting.

Parclo interchange intended to service a new suburban area.

[Patricius Maximus 236]

Gotta love parclos - they're so elegant, particularly this one. Not my style (anymore) personally since I subscribe to the school of traffic engineering that says "free flow über alles" which precludes the traffic lights essential to the bigger ones, but I still appreciate them. A free-flowing parclo would mutate into into either a cloverstack if you used directional ramps or a roundabout-parclo hybrid, where the traffic lights are replaced by roundabouts. Would still work quite well, though it's not the same beast anymore in the strict sense.

[Tarkus 6,932]

Always great to see some classic Haljackey action ("Haljack-tion"?) here!That parclo's a beauty.

Speaking of parclos . . . here's a work-in-progress:

Fully functioning, too.

@Tarkus

Those new features are cool! Though what I'm personally missing most is a double flyover piece which by the way could improve the look of my interchange below drastically. But anyway, thanks for your great work!

[clonedclone87 95]

A high capacity T-Interchange connecting the PV-9 (From Left), which serves West Drakesboro, to Central Drakesboro via the PR-20.  Many thanks to all those who make such an interchange possible, the NAM is the single biggest reason why I still prefer SC4 over any other city building game.

Bravo NAM team, may our interchanges become ever more complex!

Amen to that.

By the way, there's some nice slope work in your picture, too! The slope of that steet leading up to the avenue in the bottom of the pic is incredibly smooth, for example.

[Tarkus 6,932]

Nice work, @Razip and @clonedclone87!  And thanks to everyone for all the likes on my last one.

It's something that's been on the table as a future area of investigation, though it's seen as being a potentially very tricky thing to develop, which means it hasn't really gone much beyond the drawing board.

Back to interchanges, I have some more in the same subgenre, with different orientations . . .

And a refinement of my last one (which required some additional code) . . .

And yes, further extension of the draggable version of the Elevated Road Viaducts is something that is on the table as a potential by-product of this.

The Windmill:

 

First post in over a year, and first interchange build in 18 monts, but here we are - a fully-functional windmill interchange on angle. Next step is to integrate on-slope and diagonal height transitions which I literally downloaded yesterday from NAM 36. (I'm behind the curve a bit).

 

And a view of the windmill interchange with the proposed new downtown CBD area above.

[nos.17 5,120]

Found an old one.

[velrox 39]

[Lucario Boricua 7,028]

That's definitely a spaghetti junction, it's so hard to follow each of the paths and realizing there's so many downtown streets connecting directly to it!

 

In the meantime, I have three new interchanges I'm really proud of, part of my year-long immersion into my SC4 recreation of the Sinnoh Region!

East terminus of the Solaceon-Veilstone Freeway, where it turns into an avenue and later on to a rural expressway on its way to Sunyshore city and Hotel Grand Lake!

 

Y-interchange between Canalave-Jubilife-Solaceon Freeway (left), Sandgem-Jubilife-Eterna-Solaceon Freeway (right) and west terminus of the Solaceon-Veilstone Freeway (bottom).

 

Interchange at the heart of Jubilife City! North is towards Floaroma and Eterna, south is towards Sandgem, east is towards Oreburgh and Hearthome and west is towards Canalave. Shown before the massive urban growth around it.

There is something about this I really like. It looks so simple but it's more complex than you think. Great work!

 

I have one tip from a traffic management / realism perspective.

For the on-ramps, you have the leftmost entering lane merge right into the rightmost travel lane with no merge room. Kinda scary, and yet they do make these in real life too!

I'd suggest making a short stretch of RHW-8S so both lanes have a chance to merge. Off-ramp splits are ok.

Example of what I mean:

-But the rightmost entering lane would end in a few tiles. (It continues in my example)

New 3-way interchange. Priority to be given to turning traffic, so it is of abnormal design.

Adjustment needed to fit in bullet train network.

[Razip 153]

[bladeberkman 714]

Hey all,

Finally finished adding all of the cosmetic turn lanes to the frontage parclo and thought I'd share some close-ups.  I didn't realize the image quality of the initial picture was so bad, sorry about that. Thanks again to Haljackey for his awesome and inspirational re-creation!

Here's the center of this monster.

Exits, exits, exits...

The same exits from another angle.

Some under-pass activity.

Re-establishing the frontage networks. I'm particularly pleased with the L2, L1, L0 frontage height transition. I didn't realize that was possible until I tried it. 

The same area from another angle. 

All of this mess leading to the next frontage parclo:

A bit smaller than the first, thankfully:

Beautiful designs @bladeberkman! Holy crap!

New lateral interchange (I think that's the name???)

[Lucario Boricua 7,028]

In the USA these tend to be called right-in, right-out interchanges, useful to provide access to parallel roads in urban and suburban areas when there are nearby options for u-turns at existing major interchanges. Now, what I like best if your current set-up is the use of sound walls and a wide clear zone lined with trees (the trees alone would provide an excellent level of noise abatement, actually).

 

In the meantime...

 

More Sinnoh Region interchanges!!

 

Two partial cloverleafs in western Veilstone, with both making selective use of roundabouts to reduce the amount of intersections in downtown. The one on the right has its shape due to the competition for space with the railway.

 

Three-way stack interchange (or directional Y interchange) between Routes 213, 214 and 222, linking Pastoria, Veilstone and Sunyshore. Detailed view below:

 

 

Partial cloverleaf in Route 211, this one could use some auxiliary lanes for improved looks and functionality.

 

 

Roundabout diamond interchange in Route 214, made to look neat with wide radius curves. The predominance of agricultural and natural lands in this part of the region prompted highway engineers to design the freeway as a rural expressway (not quite a super-two, that one needs a median).

Frontage Windmill

I'll definitely have to try this one in my cities sometime.  Many of my freeways have at-grade frontage roads, and this would work nicely for a relatively compact interchange (I've made stacks but you can't really make them with through frontage roads in SC4 without an ungodly amount of right-of-way). 

I'll probably separate the off-ramps though, mirroring how the on-ramps enter separately. I've seen this done with 1970s-era 4-level stacks in Texas, where traffic making a left-hand exit leaves on the first ramp, and right-hand exiting traffic leaves second; this stack in west Fort Worth being a quintessential example.

You won’t believe this, but I happen to have driven through that exact interchange  in Fort Worth this afternoon.  I love the symmetry of these old stacks, particularly this one in Dallas. I’m very excited about the NAM Team’s work on this three-level stack flex piece.

[Lucario Boricua 7,028]

Seems there's a little fad that's going on!!

 

Is this one more of a windmill or a whirlpool/turbine/typhoon/hurricane interchange?

 

Prototype, discarded:

 

First successful attemp!! Almost perfectly symmetric, too!

 

Zoom-in of the successful attempt's central portion.

 

Zoom-in to an L1 outer ramp.

 

Zoom-in to an L2 outer ramp.

Tricky 3-way interchange, used the hilly terrain to my advantage however.

I'm a little late to the game, but this is my first interchange to feature a diagonal on-slope height transition.

After you make interchanges for 12+ years, you kinda get used to stuff. Change is always welcome though!
