I'm surprised nobody has mentioned the massive interchange with the NJ Turnpike with I-78 right near Newark International Airport. I drove on that sucker recently, and if I'm correct with my count, I counted some 18 lanes of NJ Turnpike just north of that major interchange...

There's another notable ginormous stack interchange right near the Eastern terminus of I-70 west of Baltimore... That's four levels anyway...

Amazing shots.

Do teabaggers ever protest about the $$$$$ spent building/maintaining these monstrosities?

But it's worth pointing out that the interchange actually has a very small footprint in the scheme of things. I'm anxious to see what happens when they eventually rebuild it.
It's probably the busiest in the area, but if you include the suburbs, I'd say the 355/55 in Bolingbrook and the 94/80 split in South Holland (both recently rebuilt) are taller, bigger, and more impressive from an engineering standpoint.

And if we go by area and the number of ramps, cases can be made for the Hillside Strangler and the 190/90/294 interchange in Rosemont. They're Chicago's equivalents of the East LA interchange.

When they rebuild the 90/290 interchange in Schaumburg and incorporate all those collector/distributor ramps for adjacent exits, that will be Chicago's answer to the Dallas High 5 or the 105/110 in LA.

Several interchanges in Barcelona are integrated with parkland and plaza space, which is pretty cool.

There's also the rail version... built OVER a highway interchange.

Off the top of my head the most complicated major road junction (i.e. ignoring the magic roundabouts) in the UK is probably Gravelly Hill Interchange (aka Spaghetti Junction) in Birmingham. The junction consists of several roads, a roundabout, a railway line, and several canals and rivers.

The closest London has to a complicated junction is probably Clapham Junction which dates back to 1838 (brick viaduct) and is technically composed of a variety of different junctions’ criss-crossing each other: https://maps.google.co.uk/?ll=51.471...32187&t=k&z=15

SR 520 (Washington)/RH Thomson Expressway. This one was never built, but it would've been interesting:


Answers, at last! by hey skinny, on Flickr

The RH Thomson was never built (except for a small section of unused roadway on the south end of the interchange), so the interchange was only partially built (2 ramps connect 520 to Lake Washington Blvd and the one which would've gone from northbound RH Thomson to westbound 520 is unused except for people diving into Lake Washington (the area around the interchange was never filled in)). What is there currently will be removed when 520 from I-5 to the Evergreen Point floating bridge is rebuilt.

Yes. Vigorously and frequently. Governement spending in general in a bete noir for them.

Illinois DOT is looking at various alternatives for reconstruction of the Chicago Circle Interchange. Of course, it isn't funded yet, so no one can predict when this might happen. There have been a couple of meetings to talk with stakeholders about various considerations, and the preliminary alternatives were released yesterday. PDF here. IDOT is mainly concerned about improving the throughput/reducing the backups on north-to-west and east-to-north movements, so at a minimum the alternatives give two lanes for both those ramps. Most of the alternatives also make the Dan Ryan four lanes all the way through (rather than the current three) and some push five through.

One funny thing is that they haven't yet sketched out the vertical dimensions, and some of the alternatives create nearly complete Texas-style stack interchanges that would rise 50 feet or more above the surrounding streets. I'm not crazy about that, and I think the speed gained by smoothing out the curves will be largely defeated (especially for trucks) by the elevation change required.

As a freeway historian, I'm reluctant to see the Circle's historic, almost-unique design completely blown away, but I think that will be a hard argument to make to the folks in charge of this.

We have a discussion of this going in the Chicago transportation thread.

It is funny you posted tis, I was just in Seattle 3 days ago and drove through this interchange, saw the ghost ramps, and had to wikipedia it when I got home, hehe.

WHere in Seattle is that? I was there last year. Granted I didn't drive at all when I was there, but I was on I-90 (east of town) and I-5. Is it near either of those?

I saw a couple of very large interchanges as we rode along the light rail line between Sea-Tac and downtown... I-5 and I-405? Or 205?

Its on the 520 (toll bridge)

Only half of the interchange was built, many stubs, two ramps that are being used and a third one that is not.
