Feel free to post photos and discuss large interchanges here. The topic is very general, and thus belongs in "general highway talk".
Examples:

The Golden Glades Interchange in Miami is pretty complicated. It's where I-95, FL-826 (Palmetto Expy), and the mainline Turnpike all meet up, plus a few HOV lanes for kicks.

Braided interchange in Baltimore
(https://www.aaroads.com/forum/proxy.php?request=http%3A%2F%2Fwww.infrastructurist.com%2Fwp-content%2Fuploads%2Fthe-braid.jpg&hash=c57e1287a4f183003d898086694205a7488b3d36)
Looks like it won't be braided for much longer :colorful:
Let's add to the collection with I-355 and I-88, Downers Grove & Lisle, Illinois:
http://maps.google.com/maps?hl=en&ie=UTF8&ll=41.812523,-88.037739&spn=0.046508,0.143852&t=k&z=14
That's pretty strung out as far as interchanges go.
And further south, I-55 and I-355 in Bolingbrook, Illinois:
http://maps.google.com/maps?hl=en&ie=UTF8&ll=41.704094,-88.027396&spn=0.023293,0.071926&t=k&z=15
Even includes movements to Old US-66 (Joliet Road).
I-294, I-88, and I-290 in Elmhurst, Oak Brook, and Hillside is no slouch either (aka The Hillside Strangler):
http://maps.google.com/maps?hl=en&ie=UTF8&ll=41.885346,-87.910452&spn=0.046455,0.143852&t=k&z=14
All the movements don't fit into the screen at that scale.
And to top that off, I give you the O'Hare Interchange, I-90, I-294, and I-190:
http://maps.google.com/maps?hl=en&ie=UTF8&ll=41.986642,-87.866378&spn=0.023191,0.071926&t=k&z=15
Even has movements to and from Des Plaines River Road in the interchage. It's also one of Illinois's few stack-type interchanges.
The M6/M42/M6 Toll interchange google maps link (http://maps.google.co.uk/maps?f=q&source=s_q&hl=en&geocode=&q=water+orton&sll=53.800651,-4.064941&sspn=21.172589,39.506836&ie=UTF8&hq=&hnear=Water+Orton,+Birmingham,+West+Midlands,+United+Kingdom&ll=52.500914,-1.736012&spn=0.084853,0.219727&t=k&z=13) is very spread out. Even ignoring the northern bits, and just had M6 j3a+4/M42 j7+7a+&b it's still pretty large.
I-84, 291, 384 & more in Manchester CT (http://maps.google.com/?ie=UTF8&ll=41.783825,-72.567143&spn=0.017856,0.033088&t=k&z=15)

Kittery (http://maps.google.com/?ie=UTF8&ll=43.105041,-70.743713&spn=0.017484,0.033088&t=k&z=15)
and just over the river... (http://maps.google.com/?ie=UTF8&ll=43.073434,-70.784569&spn=0.017493,0.033088&t=k&z=15)
@WNYRoadgeek: The Can of Worms isn't that bad. It's basically two directional T's tied together.
The I-81/I-690 interchange in Syracuse, NY (http://maps.google.com/?ie=UTF8&ll=43.052238,-76.148708&spn=0.007322,0.029311&t=h&z=16) is not very big, but it's complex.
The most complex interchange I've been on is I-70/US 15 in Fredrick, MD (http://maps.google.com/?ie=UTF8&ll=39.400885,-77.433529&spn=0.015487,0.058622&t=h&z=15). I was going from I-70 East to US 15 North.
Some nice double-interchanges in the Netherlands:
* near Rotterdam (http://maps.google.com/?ie=UTF8&ll=51.866793,4.584131&spn=0.039167,0.077162&t=h&z=14) (A15-A16-A38)
* near The Hague (http://maps.google.com/?ie=UTF8&ll=52.051488,4.368181&spn=0.039006,0.077162&t=h&z=14) (A4-A12-A13)
In France, there is a nice Spaghetti-junction (http://maps.google.com/?ie=UTF8&ll=48.82764,2.391243&spn=0.00522,0.009645&t=h&z=17) where the Boulevard Périphérique, the A4 and local roads meet.
In Autobahn-country Germany you'll be surprised by the uncomplicated design of most interchanges.

A few years ago there was talk of removing the freeway running along the river to the centre of Paris and replacing it with a surface level boulevard.
What about Northern VA's "mixing bowl" that's so big it requires two pics?

Image on the left is a few years older than the image on the right, which itself is at least 4 years old. Reason I say this is because the "I-95 South through ramp" opened in 2004, while the ramp from NB 95 to the Inner Loop opened in 2006.

It's tempting to go even further down by sticking the canoe in Westchester Creek.

I haven't driven through there in a while, but clearly this is one of America's biggest and most complex interchanges. I loved how the Washington Post promised that once completed motorists would be "deposited" to their desired destination points.
While the HOV-3 works well, I think VDOT should be working around the clock to either widen I-95 or build an alternate freeway altogether. Los Angeles doesn't even have commutes this brutal.

The most complicated interchange I've seen is the Newhall Interchange where I-5, I-210 and California 14 all meet at the north end of the San Fernando Valley. It's really three interchanges in one. Heading north on I-5, first you meet the 210, then perhaps a mile later, you meet the 14. In addition, the big rigs have to use truck bypass lanes on I-5 and California 14; these bypass lanes have their own interchange. I understand they're now building HOV flyovers, so when those are completed, the Newhall Interchange will have four interchanges in one! :spin:
This interchange is definitely one of the worst bottlenecks during rush hour, as it's the only route between Los Angeles and Santa Clarita or the Palmdale/Lancaster area.
The Newhall Interchange might have the most unusual history of any interchange in the country. If you'd like, I'll elaborate at a later time.
Elaborate, please!

That used to be a windmill interchange (the only one in the Netherlands), but it was reconfigured due to the construction of the Betuwe Route freight railroad.
QuoteYeah that's a mammoth one. I also like how it combines cloverleaf and stack designs yet is not a cloverstack.
It also features a fly-over with 3 lanes, that is very rare in Europe.

Is it normal in the Netherlands for the previous bridges to be left standing following a reconfiguration?

There's one here (http://maps.google.co.uk/?ie=UTF8&ll=51.95068,4.530208&spn=0.01021,0.036049&t=k&z=16) with an unused north facing ramp.
The Newhall Pass between Los Angeles and points north (Bakersfield, Fresno and so forth) was always a challenge, beginning from the days of the horse and buggy; even today, as mentioned in my earlier post about the Newhall Interchange, it's a daily traffic nightmare for commuters during rush hour. Traffic using the I-5, I-210, California 14, even I-405 has to fight this bottleneck going to places like Santa Clarita, Palmdale, or the above-mentioned cities.
The first paved road through the Newhall Pass was the original Ridge Route, parts of which can still be driven, preferably in a high-clearance vehicle. Later, both US 99 and US 6 used the pass as a split; after sharing the road through the San Fernando Valley, US 6 went through Palmdale, Lancaster and beyond, while US 99 went through Newhall, Bakersfield and beyond.
Sometime in the 1950's, the first freeway was constructed over the Newhall Pass; I believe this first freeway is now the truck bypass lanes for the current I-5. During the turn of the 1970's, the current Newhall Interchange (I-5, I-210, California 14) was constructed in this narrow pass; judging by the road cuts, they must've had to remove and/or blow up an awful lot of mountain to fit the interchange in there! :nod:
By February, 1971, the big new interchange was literally just days from opening to traffic. On February 9 of that year, a large earthquake rocked the Los Angeles area and knocked down a number of the new flyovers; one of them crushing a pickup truck with two men inside. Fortunately, the earthquake happened at 6AM, so there was very little traffic--in 1971, the Valencia/Saugus/Newhall area (now known as Santa Clarita) was still sparsely populated, as was the even more remote Palmdale/Lancaster area.
The Newhall Interchange was entirely rebuilt and finally opened in the mid-seventies. By 1994, the Santa Clarita area had exploded in population and even the once-remote Palmdale/Lancaster area had become bedroom communities for Los Angeles with the Newhall Pass becoming the aforementioned commuters' headache. :pan: On January 17, 1994 (fortunately MLK Junior Day in that year, plus it was about 4:30 AM, so traffic was virtually non-existent), another large earthquake rattled Los Angeles, collapsing some of the same bridges knocked down by the '71 tremor, plus other bridges. (Some of us might remember the TV images of a big rig and motor home trapped on a bridge whose approaches had given way, so the bridge was literally attached to nothing.) A short while later, a motorcycle officer tried to use the transition from the southbound 14 to the southbound 5, and didn't realize the bridge was gone. He rode to his death off the end of the broken roadway.
Once more, the Newhall Interchange was rebuilt, and today, they are installing HOV-only flyovers.

Assuming that was not ODOT propaganda, I assume they're talking about land area because, IIRC I-70 and I-77 are still two lanes to this day at the interchange.

Yeah, I was also wondering about that claim, and how the 4-level stack on the US-101 and SR-110 in Los Angeles completed in 1953 wasn't larger. The only thing that I could think of was total land size (including right-of-way) acquired to construct said interchange. Seems like a cop-out to me.

I'm surprised that anyone brought up 101-110 in this thread. It is not a big interchange and, for a stack, it's positively tiny. Only reaches a half mile along 101 and barely 2000 ft on 110. And the ramps stay close to the mainlines.

Yeah, I still think that's larger than the I-70/I-77 interchange, from a roadway standpoint. But again, I think they're counting ROW into the claim. I mentioned 101/110 from a historical standpoint, since it was technically the first stack in US.

Yeah, I believe that one was built that way due to geographical circumstances (101 is higher than 110), not necessarily because they had Texas-style traffic flows in mind.
Has anyone mentioned the East Los Angeles Interchange yet, where US 101, Route 60, I-5 and I-10 all join? :D (Of course, it would be considered a much larger land area if the San Bernardino Split (US 101 and I-10) interchange a mile north along the Santa Ana Freeway is included in the complex, as well as the north I-5/I-10 merge.)

70/77 is almost 4000 ft gore-to-gore along both freeways. That doesn't even include the splay in the roadways. Include those and your talking a mile along both freeways. And the splay needed to cover the left-hand left turn movements makes it take up that much more space.

What's the deal with that freeway stub in the SE corner (including the turnaround loop)?
It is possible to have a very small four-level stack if the ground conditions are favorable and maintaining a high design speed on the direct connectors is not a priority. I believe the Moskowitz signs at the Four Level in Los Angeles advise a 30 MPH maximum safe speed through the DCs.

That was supposed to be the start of an expressway (later planned as a freeway) connecting the PSB to IL 15 just west of the IL 163 intersection. There's still some interest in getting a connector from IL 15 to that ramp but I don't see it happening soon. As for the u-turn loop, I don't having any knowledge as to when or why exactly it was put in.
IL 3 was also supposed to be a freeway feeding into that interchange, but that one apparently died sometime in the 1980's.

Imagine what a full 8-level (mainlines AND HOV lanes fully interchanging)/10-level stack would be like from the ground!
QuoteImagine what a full 8-level (mainlines AND HOV lanes fully interchanging)/10-level stack would be like from the ground!
We'll have one soon at I-95/695 outside Baltimore, except it won't be 8/10 levels...
"Soon" is a relative term, Froggie--I've been waiting for more than two years for advertisement of Phase II of that project. MdTA has advertised just three real road projects in the last six months (one each last July and August, and one four days ago). Money woes continue . . .
Agree that "soon" is relative. But at least in that case, it's in-progress.
An 8 level stack would be absolutely insane, not to mention expensive.The flyovers would be incredible, and the exit to the interchange would have to be WAY back in order to have enough room for the flyover to climb to the appropriate height to make it over the stack, especially for the higher levels.In fact, your ears would probably pop at the very top.
EDIT:Also, more than likely the HOV lanes would take the higher levels as trucks couldn't handle the higher levels, and since trucks can't go on HOV lanes anyway...
Actually, a full HOV stack in a full GP stack wouldn't have 8 levels. First the mainline HOV lanes would stay with the mainline GP lanes (2 levels gone). It would also not be too difficult to glom the HOV left turn ramps onto the GP left turn ramps. So the only one that would need to have a separate level would be the HOV right turn ramps.

Line casings were turned off in all cases, as proper stack order never got completely defined correctly.
http://bickenland.lonaf.com/Maps/I-110_510.gif (http://bickenland.lonaf.com/Maps/I-110_510.gif)
I-110 runs southwest-northeast, I-510 runs more or less due north-south here.
The northeast-bound HOV/express carriageway on I-110 got borked by ArcGIS at some point, hence some of the ramps not connecting to anything. Orange lines are tunnels.
http://bickenland.lonaf.com/Maps/I-10_510.gif (http://bickenland.lonaf.com/Maps/I-10_510.gif)
I-10 runs west-east, I-510 north-south. 9-level stack, with a spui thrown in on I-510 at the artery just south of I-10.

This one's a monster and would be breathtaking to drive through. I-93 begins at the interchange, runs north with a series of braided ramps that dissolve into a C/D system. I-95 comes in from the south and hooks back to the southeast. I-510 runs northwest-southeast and through the interchange duplexing with I-95. To quickly clarify some of the stack order: the westbound I-95 mainline (the thicker red line turning through the interchange) is groundlevel; the HOV/Express line making the same movement is at the top of the stack and everything else is in between.

I-95 and I-510 come in from the west; I-95 goes north at the interchange and I-510 continues east and back south. The HOV/Express lines follow I-95 -- connector ramps from the bridge to the I-510 mainlines are missing (ArcGIS ate them, I guess). I-195 terminates at the main interchange, coming in from the south. I-595 begins at the eastern interchange, runs north. Braiding, C/Ds, surface highways joining in on the fun galore. TH 5 (blue and green US shield for reference; 'Tiaman Highway') runs from the southwest across the river, then north at the intersection (may be revised to a roundabout). I can't recall the numbers I assigned to the other routes, but ZH 172 comes to mind.
A couple notes for this fictional city: I-510 is a west-east route and functions as a transcontinental 2di, often as a toll-express route for I-10. 3dis don't adhere to the 'evens bypass, odds spur' rule, though it is observed. I-1xx is just as likely to be used as a beltway as I-6xx and vice-versa.

An 8 level stack would be absolutely insane, not to mention expensive. The flyovers would be incredible, and the exit to the interchange would have to be WAY back in order to have enough room for the flyover to climb to the appropriate height to make it over the stack, especially for the higher levels. In fact, your ears would probably pop at the very top.
These observations about the altitude of ramps at the top level do not apply if several levels are underground, in tunnel--this has been done with at least one of the I-105 stacks and also the M-40/AP-1 stack near Madrid.
BTW, is there a particular reason why you are not inserting spaces after each period? I don't mean to sound critical, but the lack of spaces does not make it easy to see where one sentence ends and the next begins.
Here it is...the full GP/HOV stack (http://www.i-95expresstolllanes.com/images/interchange_aerials/segment2_future.jpg) they're building at I-95/695. Effectively 4 levels.
Ah, nice! That gives a nice working model for my I-10/510 interchange and fixes mine to a 5-level model.
Here's one that takes up a bit of land area, the modified cloverstack at TN 840 and I-65 in Harpeth, TN:

I go through that one almost every day (the last time just 6 hours ago).
Since there are now direct ramps between I-65 and Ellington Parkway that don't touch Briley Parkway, these multiple interchanges (Briley & I-65 plus Briley & Ellington plus Dickerson Rd to I-65/Bridey) could be considered one:

I remember that interchange well because my best friend and I used the SB I-65 to SB US 31E ramps back in 2006 on our way to a Steely Dan concert...
Another Nashville-area junction that seems to be a combination of multiple interchanges would be the east end of I-440 at I-24, which seems to actually have ramps going back directly to I-40 east:

Not quite. Going on I-440 East, you have a ramp that heads to I-24 East. Then, the ramp that goes over I-24 split to join the Murfreesboro Road exit ramp (US 41, 70S) and joins the I-24 West mainline. It is possible, and I have done it a few times, to go from I-440 East to I-24, 40 West. Though I'd only do it during "slow" times as you have to cross a few lanes of traffic.
Now, going to I-440 W from I-40 West, there is a dedicated lane that does this plus a lane to I-24 East.
As this interchange is only a mile or two from my bother's apartment, I have driven it quite often.
Now that I look at it...so it seems that it's only a partially combined interchange (I-40 west does have the dedicated ramp to I-440 west, but I-440 east only directly links up to the US 70S/US 41 junction before the non-dedicate lanes of 24 west). Would it still count as one complex, like the Briley/Ellington/65 mix?
^^^
FWIW I'd say so. I generally look at that as one mess. :sombrero:
Sometimes, if I'm headed on I-40 West, I'll go down Briley Parkway itself instead to get to my brother's place, as this way you need to get off at the Briley Parkway exit on I-24 East and that ramp from I-40 W is a left join and you have to slide across 4 lanes of traffic to get from that ramp to the Briley exit.

Well sorry I'm not up to your "standards". I pretty sure you wanted to sound all "smarty pants" but thats ok. There. I put a space after the period. Happy? :happy:
EDIT: Sorry to sound like an A$$hole, but I'm sick and I take BS from people I deal with everyday at work. I certainly don't need the BS from being judged by some guy half across the f-ing planet. :-/
Cool it.
Riverside Frwy, it was not my intention to badger you about punctuation. It just seemed to me that it would be more difficult to touch-type sentences without spaces after the periods (and colons) than simply to insert the spaces. I wondered, therefore, if you had a particular reason for omitting the spaces, and if so, what that was.
The one that gives a lot of people in the Cincinnati area headaches is the I-75/I-71 junction. In less than 1/2 mile there are six SB I-75 exits, 5 NB I-71/I-75 Exits, Two SB I-71 Exits, and Three EB US 50 Exits. There are also Three NB I-75 on-ramps, Two SB on-ramps, and three WB US 50 on-ramps. The biggest cause of traffic tie-ups at this interchange is the fact that I-75 and I-71 Southbound traffic combines into four lanes at the Brent Spence Bridge. There is a plan in the works to build a new, larger bridge to replace the current one.

Don't forget I-471 at the east end of that whole mess...
