Interchange Types

I want to know what types of interchanges exist in real life and fictional interchanges.


Scott5114

The most common types, in both real life and fiction, are:

- Diamond
- Trumpet
- Cloverleaf
- Partial cloverleaf (parclo)
- Single-point urban interchange (SPUI)
- Diverging diamond interchange (DDI)
- Stack (there are a half-dozen subtypes of stack)
- Volleyball

A Google image search should bring up diagrams of each of these.

For fictional interchanges, pretty much any configuration where there's ramps between a freeway and another road will count as an interchange, so you have an infinite number of types, many of which wouldn't be feasible in real life.

Don't forget "turbine" and "mixing bowl".

While full turbine interchanges exist, they are relatively rare.  More common is to have 1 to 3 of the busiest left-turn movements as turbine ramps, while the rest are cloverleaf-type loops.

Examples:
1 ramp - I-75/I-275 Cincinnati
2 ramps - I-70/I-270 Columbus
3 ramps - I-70/I-75 "Crossroads of America" near Dayton

I'm not sure, but I think a mixing bowl is similar to a turbine, but with tighter and more elevated ramps.

An example of a full turbine interchange would be I-485 / I-85 northeast of Charlotte, NC.

I always figured a mixing bowl is a term used by locals to describe a large interchange area, usually made up of more than two individual roadways where unconventional ramp routings and routes are needed to make all the connections. A spaghetti interchange is also a term used for these type interchanges.

Here's a pretty good thread that featured a scavenger hunt for the different types:

Here is an interchange that is unique, as in the only one on Earth constructed this way.  US 35/OH 32 near Jackson, OH: https://goo.gl/maps/cGm49ZJCu7zUWKTg9

Both US 35 and OH 32 are grade-separated and have ramps that exit to the other highway.  Right turning traffic merges with the other highway, however, left turning traffic at all four ramps comes to a stop and must make the left at-grade.

Turbines are also called turbans, depending on your source.

Wichita has a full one at US-81 & US-400.

Isn't US 23/OH 32 similar?

It's not a full turbine anymore, since the northbound to westbound ramp was rebuilt.

US-23 is the through highway in that instance, and just simply has a standard diamond interchange with OH-32.

So now it's a 3/4 turbine, then?

Hey, OP here, and I wonder what kind of hybrid interchange types exist or are fictional. I know there are a few that fellow members on here either created or mentioned but, of course, they are all over and I'm sure that there are some that I don't even know exist. The main reason I'm asking for different interchange types is that I have a YT channel where some of the stuff I do is build different interchanges and need ideas on what interchange to build so I'm going to do more unique interchanges.

I don't particularly like this page. There is good information, but they clearly didn't do as much research as one would expect for a page that is trying to give examples of interchanges. You can tell just by the names he gives them, as well as the fact that he says the Parclo B4 doesn't exist. It does, just mush less common. He does actually give one example, so at least there is that.

It reminds me of the time I was at the breakfast table at a seminary with my dad.  The professor eating across the table from me learned that I was working for a Christian publishing house at the time, so he asked me what I thought of the Bible translation that the publishing house was known for.  I didn't really care for it, and I told him as much.  Then he said he hoped I might consider reevaluating it at some point–and to look at the list of contributors.  Yeah, it turns out he had personally worked on translating the book of Isaiah.

(My dad still ended up earning his second master's degree, so I guess the prof didn't flunk him on my account.)

Here in NJ around Maple Shade, we have something relatively close to your very last example on the page (6 way interchange).  It's actually where 3 jersey-style highways meet:  NJ 73, 38 & 41.  Within the middle of the triangle is a few businesses, and other businesses have driveways or roads that connect directly or indirectly with the immediate area.  https://goo.gl/maps/LZy9ZkBRFcqpczsS7

I mean, with any sort of creative work (I know, this is a translation of the Word of God so some people would say that the humans involved are not actually creating anything, but play along for the sake of the point) if the creator asks someone's honest opinion and they get it, "I don't care for it" is an option that should be on the table, or else why bother asking? I'm sure lots of people wouldn't care for the stuff I've spent a lot of time writing and drawing, and that's okay. The risk someone isn't going to like it is part of the inherent risk of being an artist, whether that art is translating, writing, drawing, or anything else.

What it reminds me of was this.
