Show us Your Interchanges!

[Jazzmaster 716]

I thought about the suggestion about a highway splitter rather than an exit. I used a RHW-8 to two RHW-4's and I think it looks much more elegant than the RHW6 exits. You guys can be the judges of that though

It should be noted that it was because of me that the "Splitters" you used are now called "8S D2 Ramps", and would be more fitting to refer to the new ramp naming, because that's how every ramp is be named.

And unless you like the elongation of 8S D2's coupled with RHW-4 curves (which would make for a nice buffer, anyway), there are also 8S E2 ramps; They're the diagonal-branch equivalent of the 8S D2, and arguably make a setup like that more compact, unless there's absolutely no room to shrink down. (Don't be deterred by the lack of starters on the 6S B2's and 8S D2's; That's what fillers are for.)

I should also suggest a Diagonal Jagged Edges Mod for the terrain (which, by the way, is it the Columbus Terrain Mod?); It makes usage of your highway walls a bit cleaner.

Thanks GDI, that's the point I was trying to make all along.

For the record, this needs updating (RHW-3 and RHW-2 ramps need reclassification), but here's the Periodic Table of RHW Ramps, courtesy of the Dmitri Mendeleev of RHW himself. This is how every ramp in the Modular Interchange System is named.

Thanks for all the high praises guys! That's actually my first below grade (sunken?) interchange, and interchange of that design. I thought about the suggestion about a highway splitter rather than an exit. I used a RHW-8 to two RHW-4's and I think it looks much more elegant than the RHW6 exits. You guys can be the judges of that though

And then here is the main interchange, and unfortunately due to the lack of ELRHW8, I can't use the RHW8 splitters on the East and West sides of the interchange.

Nice looking but you may want to make it a clover stack or a clover fold due to the VERY nasty weaving.

[Ion_Cannon 677]

Thanks for the info Ganaram DI and mrtnrln your slide was very helpful, so thanks to you both.

[WiiGoGetter 65]

This is one of my weirdest interchanges

[Haljackey 17,270]

@ -JD-: I agree with what Ganaram is saying. If you change the RHW-8S to dual (parallel) RHW-4 splitters [type D2], to the design that has one of the RHW-4s going on the diagonal [type E2], you'll be able to extend your RHW-S for a few extra tiles on each side. This will help reduce weaving as more merge room is given.

@ WiiBowDash: Interesting creation. I used to make a lot of junctions like that with the Maxis Highway that used two t-bone interchanges. It's a good way to save some space if you have little or no room for ramps on the one corner, although it isn't as efficient as a standard 4-way interchange.

It's also very popular for interchanges with tolled highways. I have quite a few SC4 examples, but here's two. IRL practically every tollroad uses this interchange type, except in high capacity situations (ie NYC)

That and electronically tolled highways don't have a need for that setup. Though the one you provided are indeed common if toll booths are used.

A new interchange of mine, between the A3 Freeway(Chafkon Scenic Bypass) and the Northeast Highway:

[XV infinity VX 18]

Part of my new highway system in my new country [Adion Republic]. The grid lines are one [i was constructing something and forgot to turn them off] but I am proud of it. Simple and not much weaving. I plan to add excel/deceleration lanes when it demands it.

[Legobuilder123 24]

Y-Interchange in my developing cities. This is one of my finest interchanges I've made so far...

-JD- : I like yours, looks fancy!

Blue Lightning : I gotta tip my hat to you, it looks great!

Haljackey : Thats creative! i never though of that design before.

I've never seen that kind of interchange on any tollroad in TX. All of ours use the standard stack interchanges to meet other freeways, and slip ramps to the frontage roads as with most Texan freeways. The tollbooths are placed on the freeway itself or at the offramps (in some cases both). In Houston and most of the rest of the state, the tolls are a mix of manned and electronic; the only difference is that the electronic tollroads don't require traffic to slow or stop to pay tolls.

Ah, yes, Texas. They're interesting and simply place the tolls on the ramps. The reasoning behind using the dual trumpet interchange in other places is cost and efficiency (although only suitable for medium levels of traffic). Instead of having to build, say, 3 booths at each ramp (for a total of 8 movements X 3 booths = 24 booths), you can build 14 booths in a single place which is easier to manage (staff only need to stay in the plaza instead of driving out to the separate booths) and has more failsafe capability.

Course this all doesn't matter if it's all electronic

EDIT: You can also get interesting setups like this.

[Haljackey 17,270]

Ya the double-trumpet is a good way to connect to toll highways / turnpikes that still use toll booths. The toll highway round here is electronic and nearly of the junctions are parclos.

Nathan: Interesting trumpet setup connecting that RHW-2!

Smartbylaw: Good job with that T-interchange! Very good use of space.

Legobuilder: Nice partial-y interchange! I like how both highways curve.

Anyways, I made a UDI video which showcases some of the interchanges I've posted to this thread. Enjoy the 'epic drive'.

A kinda big interchange but its home to my widest RHW at 15 lanes

I fixed a nasty weave and made weird interchange its right next to the main mass tranis hub in the area and a airport

Can you make that?

This is what I used to do with the MHW to implement tolls.

EDIT: You can also get interesting setups like this.

In most new tollroads in TX, the tolls are taken on the freeway main lanes rather than at the ramps. Plus, they're becoming increasingly reliant on electronic tolling here, so the newest roads may have just 1 or 2 traditional tollbooths at each plaza,or they may not have any normal booths at all. The northeast section of the Sam Houston Tollway is all-electronic, and has only gantries above the roadway that automatically read each vehicle as it passes.

[simlink 1,098]

In Canada we have Highway 407 (in Ontario) which is officially 407ETR, Express Toll Route. There are no toll booths, it is done by overhead cameras that take photos of your license plate, (and transponders), and then mails you the bill. More info on the wikipedia article here.

Interesting note: the highway is leased to a private consortium.

[Markus J 242]

Here is something you don't see much of, a desert city...

Also, this is a similar interchange to one I've made a tutorial on, at SC4 Devotion (Different user name), The bridges were proving, problem mattic by being so close and over lapping so much, kept glitching, but eventually got it too work. I feel it's a nice size, not too big, not too small. I've built up around it since this picture was taken.

Anyway nice stuff, some RHW's really inspire me.

Edit: I should add, it's nice the RHW's are alot more slope friendly now (the on/off ramps mostly) because most of this was built on a gradual slope. Can you tell?

A trumpet:

The same trumpet converted into a six-point parclo with two lights (I would have fully grade-separated but the RHW mod isn't quite fully developed for what I want):

(great work on the new FARHW ramps, by the way)

@MamaLuigi945: Nice pic! The area looks really good! Like the interchange as well. Just remember to use jpegs, that took a while to load.

[Haljackey 17,270]

SA, wonderful diagonal trumpet and reverse parclo!

Niellezzz: Those are some very unique creations!

Got some new stuff to show. Click images for full size!

Let's start off with an oldie. A special interchange with exits dedicated to reaching a transit hub while it was still in it's infancy:

The highway widening and the MHW connection zoomed out:

My only Diverging Diamond Interchange. It is over capacity too.

-I guess I can widen the on-off ramps to two lanes but that's about it.

And finally a mosaic of the most recent RHW reconstruction I did. Again, click for full size!
