Five (or more) way freeway interchanges

[flowmotion]

You have to love it when at least three freeways intersect and create a massive pile of high-speed concrete spaghetti ramps. Post any examples you know of, preferably with a map link.

In California, the East Los Angeles Interchange: http://goo.gl/maps/lgPqA
I-5, I-10, US-101, CA-60

And, the 'Orange Crush': http://goo.gl/maps/UaLJM
I-5, CA-22, CA-57

One of my favorites in New York: http://goo.gl/maps/V1yRZ
I-95, I-278, I-678, I-295, Hutchinson River Pkwy

And of course, the Newark Airport interchange: http://goo.gl/maps/Q0I2V
I-78, US-1/9, US-22, NJ-21, Airport exit 
(In my opinion, the turnpike has a separate interchange here. Is there anything which tops this one?)

Bryan Park Interchange in Richmond: I-95, I-64, I-195, VA 197 (non-freeway)

Actually seems to be a smooshed 4-way freeway interchange with some local access ramps, but I like it.

Two others in Southern California:

1) the Kellogg Interchange, east of Los Angeles (I-10, CA 57, CA 71): http://goo.gl/maps/7TUKB

2) In San Diego, near Sea World (I-5, I-8, Camino Del Rio (former CA 209)): http://goo.gl/maps/rnJ65

Spaghetti Junction in Louisville. I-64, I-65 and I-71 all coming together.

I was just trying to design a stack interchange for an imaginary 6-way scenario (3 interstates crossing at a single point, different levels of course) yesterday.

It's a bit of a nightmare. And don't know how many levels one would need for it to be functional.

It's fictional, but it fits the thread's topic.



Remember this is just a quick sketch, nothing to get angry about.

Only access this design doesn't allow is turning to the freeway immediately to the left, but it does allow left turns to the freeway after that (and any other kind of access you'd want).

EDIT: (I could technically could throw in cloverleaf-style loop ramps between the yellow roads, this would permit left turns to the freeways immediately to the left)

Valley Forge interchange(s) in PA: I-76 (PA Turnpike West & Schuykill), I-276 (PA Turnpike East), US 202, and US 422.  And throw one of the largest malls in America in the middle of it for good measure.

3 in lower NY State

Newburgh Interchange in NY (I-84, I-87, NY 300, NY 17K) Streamlined recently with the 84 to Thruway direct connection.

NY Thruway near Woodbury Toll Barrier: I-87, NY 17 (arterial and Future I-86), NY 32, US 6, and even a direct connection to Woodbury Common Outlets.

I-87, I-287, Saw Mill Parkway, NY 119 (local road) at junction of Thruway and Cross Westchester Expressway.

[NE2]

The Bruckner may be the 'purest' 6-way interchange (follow the names, not the route numbers).

I-95/395/495 near DC will soon be 8-way, if you count the HOV roadways as separate freeways

Here's one from southeast Michigan:

Located on the Farmington Hills/Novi city limits, I-96, I-275, I-696, M-5 and 12 Mile Road (east-west surface street to the north) all converge in this seven-way interchange.

(drawing of 12-way interchange)

Whoah! That's a large 12-way!    From now on, I'm gonna commute on residential streets instead of getting stuck in traffic on this interchange.

The Springfield Interchange in Fairfax County, Virginia (nominally I-95/I-395/I-495) could be considered a six-way interchange if Va. 644 (Franconia Road/Old Keene Mill Road) is included (and I think it should be, since it is signed on all of the approaches).

And there's the matter of the express lanes, as pointed out by someone else.

Neat! It would be interesting to see this in 3D, it looks like some of the ramps are real roller-coasters.

[flowmotion]

Here's one in Minneapolis which only has limited access between the roadways: http://goo.gl/maps/TT8dB

I-35W, I-94, MN-55 Hiawatha Ave, former MN-122/US-12 Washington Ave Bridge (which is being downgraded to a non-freeway).

[Truvelo]

This one is five way but movements between the two north facing freeways are taken care of by separate diamond interchanges.

^ The true definition of "spaghetti junction." Here a few other candidates for this thread...

-While it doesn't look very impressive, here's the junction between I-95, I-295, I-495, US 202 , and DE 141 just to the south of Wilmington, DE.

-North Jersey seems to have a lot of complex interchanges, including the one right next to the Newark Airport mentioned in the original post. Here's another large one in Perth Amboy between the Garden State Parkway, US 9, NJ 440, and several other side streets and county routes.

-While it may be considered multiple interchanges, I'm putting it up here anyway. The intersection between I-95/NJ Turnpike, US 1-9/46, US 9W, Palisades Parkway, NJ 4, and NJ 67 in Fort Lee, NJ.

Queens
Kew Gardens Interchange:
I-678 Van Wick Expressway N-S
Grand Central Parkway E - N-NW
Jackie Robinson (Interboro) Parkway W
Union Turnpike E-W

The Rosemont Interchange near O'Hare: http://maps.google.com/maps?hl=en&ll=41.986706,-87.864618&spn=0.023446,0.038581&t=h&z=15

There is also the Dan Ryan stub, I-90/I-94 and I-55 (depending upong where we are drawing the line between five-way and two adjacent interchanges):
http://maps.google.com/maps?q=chicago,+il&hl=en&ll=41.846323,-87.632682&spn=0.013507,0.033023&sll=29.77572,-95.25816&sspn=0.015738,0.033023&hnear=Chicago,+Cook,+IL&t=k&z=16

Chicagoland also had a couple more proposed that weren't built, including a US 45 corridor freeway running southward from the I-55/I-294 mess, and possibly one with a North Avenue Expressway in the area of the I-290/I-294/US 20/IL 64 mess.

Ones in other states:

* I-10, I-610, and US 90 on the east side of Houston:
http://maps.google.com/maps?q=houston,+tx&hl=en&ll=29.77572,-95.25816&spn=0.015738,0.033023&sll=29.776056,-95.258825&sspn=0.015738,0.033023&t=k&hnear=Houston,+Harris,+Texas&z=16

* The Triangle in Grandview, MO, consisting of I-470, I-435, and US 71:
http://maps.google.com/maps?q=kansas+city,+mo&hl=en&ll=38.938816,-94.525809&spn=0.028206,0.066047&sll=34.29353,-97.761841&sspn=3.834329,8.453979&hnear=Kansas+City,+Jackson,+Missouri&t=k&z=15

EDIT:  Didn't see that Truvelo beat me to mentioning the Triangle.

Does I-495/US 3/Lowell Connector count as a five-way freeway interchange? It's almost a situation of separate interchanges braided or overlapped, but not quite--for example, the exit from US 3 NB to I-495 NB basically uses the southernmost end of the Connector to start making the move. Other moves are outright integrated, like the Connector SB to US 3 NB, which splits and then merges with the ramp from 495 SB.  I believe that all movements are possible from all the roads.

Had to google to figure out what you are referring to, but I certainly think it qualifies. (You could even call it a "clover-trumpet".)

2) In San Diego, near Sea World (I-5, I-8, Camino Del Rio (former CA 209)): http://goo.gl/maps/rnJ65

immediately to the west is this:

http://goo.gl/maps/8hjAV

those can locally be considered freeways, as all grades are separated and the only access control is via ramps.

[roadman65]

The Golden Glades interchange in Florida.  I-95/ FL Turnpike/ US 441/ FL 9/ FL 826 all converge on each other near Miami.

The State Road 84 Interchange on Florida's Turnpike where the Turnpike, FL 84, US 441, & I-595 intersect.

[vdeane]

I-490/I-590/NY 590/NY 96: http://goo.gl/maps/Wxo61

Not really.  Only us roadgeeks, NYSDOT, and the FHWA consider I-590 and NY 590 to be different roads; for everyone else, Route 590 is one continuous freeway.  NY 96 is not a freeway either, nor do any of the freeways have direct interchange access to it (though there is a ramp from it and the I-490 ramps to Winton Road and I-590 ramp to Highland Ave come close).
