Show us Your Interchanges!

[Patricius Maximus 236]

Well, you've finally equaled some of the stranger ramps I've created .

[Tarkus 6,932]

Here's a preview of an interim version of a new interchange coming to Tarkusian Cities . . .

It's interim as I still need to make diagonal D1 and E1 ramps to get rid of the nasty merges, and that highway is indeed planned to go over the river (and through the woods).

Left side or right side?

EDIT: Decided to keep both, here's some progress

[Squizie3 13]

After years of enjoying SimCity 4 with NAM, I thought I'd post some of my more recent cities' interchanges here. As you can see, I like to make my interchanges as tight as possible, without becoming unrealistic.

I'll begin with the northernmost exit. (Note: north is actually at the bottom of this picture.) This is just a simple and compact diamond interchange with an extra level of railway tracks underneath. As a bonus this picture also features a double railway interchange.

Next up: the eastern interchange. (Note: north is now at the top of the picture.) This wasn't an easy one to create, and I am rather proud if it. In fact, this is a double T-interchange: one for through traffic on level 1, and one for the exit on level 0. There is an extra exit on the through traffic viaduct a little further away from the interchange. This double exit setup eased traffic congestion a lot in comparison to a setup with only one exit, but it required a rather challenging interchange.

Further down the road: the central interchange and exit. I created a setup where the highway to the south leaves the interchange diagonally. There's also an exit integrated in the interchange.

The western interchange is located further west through the highway tunnel. This is again a double interchange with one being an exit to the industrial zone, and another being an exit straight into the city via a highway tunnel in southern direction.

The tunnel from the exit ends at a central roundabout in one of the city's cores. (Note: north is on the left of this picture.)

Now there's only one interchange in this city I didn't cover yet: the southern interchange and exit. This one is situated on the highway that leaves the 'central interchange' diagonally in south-eastern direction, as you might remember. The interchange and exit features collector-distributor lanes, because otherwise the exits and entrances would sit rather close to each other. The area is not yet fully developed, so the highway may get an extra exit further down the road in south-western direction later on. Both the 4-lane highway in the south-western direction and the 2-lane highway in the south-eastern direction just lead to the city's boundaries for now, without having developed area's surrounding it yet. This makes the interchange being almost unused for now. The exits are used however.

So, that's what I have for this 'Show us your...' thread. Hope you enjoyed it!

[Haljackey 17,270]

Very nice!

I have finished my interchange shown in my last post. Decided to keep the asymmetry.

Project also included a half interchange to the north

EDIT: Just realized I screwed up one of the road markings. Ah well... Fixed now in my game lol

Roughed-in a new highway (and rail) that climbs a mountain

How should it configure with the 3-way interchange?

 

I got a few ideas - curious to know if anyone likes a certain configuration. Also welcome suggestions!

These are just conceptual. Real build will likely be different / larger

@Haljackey From my personal preference, I like the third option the best for its relative compactness compared to the other two possible options. However, from what I see, it could be more space efficient, but there might be special needs that I may not have known, such as traffic levels. I am just tipping my few cents in and ultimately you decide what is truly best. 

[Haljackey 17,270]

Finished the interchange expansion from 3 way to 4 way.

All of the original trumpet connections remain

I call this the ramp forest

That ramp forest is really something spectacular--the whole interchange concept with the bent 4-way setup is rather neat!

And now, for something completely different . . . it's more an intersection than an interchange, since there's no grade-separation, but this is probably as good a place to put it as any.

No idea when its components will get released, but it's by-and-large operational at this point.

Whoa, this seems like an odd configuration! I take it that these exist in the US, then? Because I'm pretty sure I have never come across anything like it in any European country I've ever been to. Truth be told, when I took the first superficial glance at that picture, I was like "Now this looks somewhat clunk... hey, wait a second!"

It's a continuous flow intersection. Often used by people who play modded Cities Skylines. No idea how to implement this interchange with NAM though

First time I saw one, it looked a bit odd, too, but much like the Diverging Diamond (and actually probably a bit quicker with this one for me), once I understood the logic, it made sense.  They are mostly a US phenomenon, being most popular in Utah and Colorado.  There is, oddly enough, an isolated (partial and well-disguised) one in Germany, in Hamburg, as well as a T-intersection version in the UK, near Swindon (also home of the Magic Roundabout).

The implementation here just uses an expansion to the NAM's new FLEX Turn Lane feature, and the whole thing was made out of mostly draggable components, with some already existing FLEX pieces.  There will probably be full pre-built FLEX version made available for those who don't want to manually place the FLEX pieces and do the drag pattern, but even the latter is surprisingly intuitive.

A T-intersection with the main highway from north to west. Tot he east another split (not on screen). The two roundabouts in the left corner (the two in the middle) are the on and off ramps to all directions. I kept in mind that first the traffic must leave the roundabout (on ramp) and then the traffic joins (off ramp), instead of the other way round. This is to prevent traffic jams (I hope).

When I began with this I had some issues with drawing L3 over several parallel highways. They broke and I couldn’t fix that. So, this is how it ends.

Interchange I made in Expressville with decent traffic, it will handle the traffic from downtown Expressville into the suburbs:

One at he northeast part of the city that will be frequently used once the surrounding cities are developed:

And one from the south part of the city that handles the traffic entering from my Shinewood district into the suburbs:

This valley trumpet too me way too long to build

Slope mod very unforgiving but managed to pull it off.

+ Bonus diamond further down the road - long ramps due to slope tolerance

[bladeberkman 714]

Howdy y'all,

The last time I made a turbine (here), I was unhappy with the through-capacity. Here's another with more lanes and a frontage network. In spite of the larger footprint, it doesn't look too boxy (which tends to happen the larger these turbines get). 

I'm particularly happy with this bit of compact, diagonal, flex-height trickery.  1) Place the L1 Flex Fly; 2) Remove the L1 Flex Fly stub with the RHW disconnector; 3) Incorrectly overlap a diagonal L1 Flex Height transition on the level ground below (producing a sharp/steep, glitched look); 4) Use the 7.5m ground-raiser to raise some nearby terrain to the L1 Flex Fly level; 5) Plop individual road tiles to raise the adjacent terrain and "lift" the glitched L1 Flex Height transition to the corresponding L1 Flex Fly level; 6) draw the ramp.

First this and than that. oops, wrong order so begin again. Recognizable how you sometimes must hocus pocus with puzzle pieces. 

[Razip 153]

Got back to SC4 yesterday, finished building this beauty a few minutes ago!

UPD: Made one of the height transitions a bit longer.

I am not as talented as many of you are.  Maybe these have been created before but I was wondering if any of you would make some of these intersections of my hometown of Louisville, KY. The first one is I-264 meets I-65. Just north of Louisville International Airport. Part of the intersection also leads to the airport and Kentucky Fair & Expo Center.

The next intersection is known as Spaghetti Junction where I-65, I-64, and I-71 meet at the Ohio River in downtown.  It was recently redone with an additional bridge to support 6 lanes of I-65 north.

Here are some interchanges I've made for a city I've been working on.

[bladeberkman 714]

Looks simple, doesn't it?  

[art128 4,618]

I'm interested to know how you made such a good gradient using the smooth curves. It's something I'm always struggling with when I use the RHW.

Do you have the God Mode during mayor mode mod? I know I use it all the time to soften the terrain or make terrains more natural if I screw them up.

Heres an interchange I made that takes advantage of the onslope transition from L1 to L2 rhw.
