Huge Interchanges

[haljackey]

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

Examples:

Stack in Shanghai


Turbine in Dubai


Cloverstack in Brampton


Mammoth in LA


High Five in Dallas


Two level monster in Toronto


"Circle" interchange in Chicago


Moreland interchange in Atlanta


Spaghetti Junction in Birmingham


Rainbow (Napau) interchange in Tokyo


Braided interchange in Baltimore

I-95/I-295/I-495/US 202/DE 141 interchange near Newport, DE...
http://maps.google.com/maps?ie=UTF8&hl=en&ll=39.705899,-75.596194&spn=0.0208,0.045362&t=h&z=15

This may count as multiple interchanges, but how about I-95 (NJ Turnpike)/I-78/US 1-9/US 22 at the Newark Airport in NJ...
http://maps.google.com/maps?ie=UTF8&hl=en&ll=40.709532,-74.165869&spn=0.020494,0.045362&t=h&z=15

There is also the Bruckner Interchange in New York City...
http://maps.google.com/maps?ie=UTF8&hl=en&ll=40.829138,-73.839991&spn=0.010229,0.022681&t=h&z=16

How about I-90 (Mass Pike)/I-93/US 1/MA 3 in Boston...
http://maps.google.com/maps?ie=UTF8&hl=en&ll=42.347761,-71.057789&spn=0.009991,0.022681&t=h&z=16

And just to the north in Boston is I-93 at US 1 (and the surrounding ramps to MA 28)...

I-95/US 6/RI 10 in Providence, RI could count as one...
http://maps.google.com/maps?ie=UTF8&hl=en&ll=41.825572,-71.418085&spn=0.010074,0.022681&t=h&z=16

Not a interchange but here's the Basketweave in Toronto also along ON 401:

Ontario's only full 4 level stack interchange at ON 400 and 407:

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.

[WNYroadgeek]

I give you the Can of Worms!



And the old version:



(I-490, I-590, and NY 590 in Rochester)

Braided interchange in Baltimore

Looks like it won't be braided for much longer

[Brandon]

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 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

Kittery
and just over the river...

@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 is not very big, but it's complex.

The most complex interchange I've been on is I-70/US 15 in Fredrick, MD.  I was going from I-70 East to US 15 North.

Some nice double-interchanges in the Netherlands:
* near Rotterdam (A15-A16-A38)
* near The Hague (A4-A12-A13)

In France, there is a nice Spaghetti-junction 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.

[Truvelo]

In France, there is a nice Spaghetti-junction where the Boulevard Périphérique, the A4 and local roads meet.

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.

[architect77]

What about Northern VA's "mixing bowl" that's so big it requires two pics?

[froggie]

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.

But I like that you had some actual photos...

[Duke87]

There is also the Bruckner Interchange in New York City...
http://maps.google.com/maps?ie=UTF8&hl=en&ll=40.829138,-73.839991&spn=0.010229,0.022681&t=h&z=16

That interchange is even more fun from underneath.



It's tempting to go even further down by sticking the canoe in Westchester Creek. Tempting. But I'd rather not have tentacles growing out of my face.

Yeah that's a mammoth one.  I also like how it combines cloverleaf and stack designs yet is not a cloverstack.

[joseph1723]

Here's another Ontario one this one is a combination of turbine and clover designs:

ON 401 and Allen Road

The same interchange in 1967:

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.

Exit 127 on the Garden State Parkway for Interstate 287, NJ 440, and US 9:

near Rotterdam (A15-A16-A38)

Crazy stuff. I'd be interested in learning the story behind this one nearby...

[hm insulators]

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!

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.

[Bickendan]

Elaborate, please!
