Interchange by name

[Darkchylde]

Well, in this area, there's the 610 Split (the western interchange between I-10 and I-610 in New Orleans), less often the 610 Merge (the eastern I-10/I-610 partial interchange) and the Megachange (I-10/US 90 Business/US 90, also in New Orleans - not used in the media or traffic reports, but rather by some locals).

Very few of the other interchanges here are referred to by special names that I've heard, often just referred to as the (crossing roadway) exit, like the Causeway exit or the Airline exit.

Braintree, MA:

I-93/MA 3 split interchange (EXIT 7) is referred to as the "Braintree Split" in various news and traffic reports.

Pennsylvania - Breezewood (I-70/I-76/US-30)

Many toll roads have named interchanges.  The Breezewood interchange is in reference to the PA Turnpike.

Kind of abbreviated to "The Split" (Serius-XM) gave traffic reports for I-93 from the "Tip" (O'Neal Tunnel) to the Split"

PA Turnpike has a name for every interchange - it's on the BGSs (NE Extension as well)

The term, Braintree Split has been around a lot longer.

I'm well aware of the PA Turnpike having names for all of its interchanges; I was simply pointing out that many toll roads have named interchanges whether they're called out on the signs or not.

Many European countries more or less consistently name and sign their freeway-to-freeway interchanges. Examples are Belgium, Denmark, Germany, the Netherlands, Poland, Luxembourg, Switzerland and Austria. These interchange names are widely known. It fits in the somewhat European tradition to have names for the exits. Though most countries use exit numbers as well, the names are generally more well-known than the numbers.

A German traffic report will likely say "A3 Köln richtung Frankfurt, zwischen Kreuz Leverkusen und Köln-Dellbrück 5 kilometer stau" (A3, Cologne towards Frankfurt, between motorway interchange Leverkusen and Cologne-Dellbrück 5 kilometers stationary traffic). Similar reports can be heard in the Netherlands and Belgium, though in Belgium they sometimes omit the length of the traffic jam. Some radio stations use delays instead of length, but this proves to be unreliable in case of stationary traffic.

in CA, close to each other:

101 at 110 is the Four-Level Interchange.

5/10/101/60 is the East LA Interchange.

And not too far away from both of those is 10/101, the San Bernardino Split (US 60's former western terminus).

Nevada
Spaghetti Bowl (I-15/I-515 Las Vegas)


What interchanges do you know have names mentioned (media, official, whatever)

Nevada actually has two "Spaghetti Bowl" interchanges: The aforementioned I-15/I-515/US 93/US 95 interchange in Las Vegas, and also the I-80/US 395 (hidden I-580) interchange in Reno. Both Spaghetti Bowls are referred to as such by traffic reporters, media, and also by NDOT.


An unofficial/colloquial named interchange:
The "Rainbow Curve" - US 95/Summerlin Pkwy/Rainbow Blvd (SR 595) in Las Vegas. So named because US 95 makes a 90° curve as it passes under Rainbow Blvd. Sometimes referred to by NDOT, but mostly used by locals and traffic reporters.


Nevada also has some named interchanges based on freeway exits and/or former communities. These are older references that may appear on some maps and NDOT publications, but are generally unknown by the public. For example, the I-15/US 93 interchange north of Las Vegas is the Garnet Interchange, named I believe for a former townsite that was located near the junction. NDOT names many regular highway junctions in a similar fashion.

[Perfxion]

I know its nothing official, but I know a few up in Northern Houston call all beltway 8 to another freeway(The two I-10 and the I-45 north mainly) the hill exchange. Due to that being a 4 level stack and that top ramp being the highest elevation a person can drive to in the city. Since the city is almost all flat land.

[Revive 755]

From the southern half of Illinois (some of these may just be names I've heard IDOT use):

* The PSB Complex:  I-55/64/70 at IL 3 and the Tudor/Pigott ramps

* The Tri-Level:  I-55/70 at I-64

* The Three I:  I-55 at I-70 and I-270

Luis Echeverría Álvarez & Paseo de la Refomra a.k.a. Fundadores, in Saltillo (Coahuila) is known as 'El Indio'.

I only know this because I recently spent a lot of time looking through 7,631,258,305,022½ SkyscraperCity posts about renovations along that corridor, and kept wondering where the heck this oft-referred-to street named El Indio was located.

In Columbus:

670 Split: I-70 & I-670
Spring-Sandusky: I-670 & OH 315
Fort Hayes: I-71 & I-670
Mound-Sandusky or West Split: I-70 & I-71 & OH 315
East Split: I-70 & I-71

[nwi_navigator_1181]

I apologize for bumping this thread, but we do have one here in NW Indiana that does have an official name, though it is rarely used.

The Northwest Connector: the ramp connecting I-65 North to I-80/94 West, and connecting I-80/94 East to I-65 South (with Ridge Road added in 2008).

[mgk920]

One thing I noticed is that many interchanges are referred to by a name - which obviously makes thing easier for endpoints.

Names that I know of are:

Wisconsin: (I think notorious for named interchanges)
Marquette (I-43/94/794 - Downtown Milwaukee)
Zoo (I-94/I-894/US 45 - West Allis)
Hale (I-43/I-894 - SW of Milwaukee)
Mitchell (I-43/I-894/I-94 - South side near Airport)
Stadium (I-94/US 41 near Miller Park)
Badger (Split of I-94 from I-39/I-90 at WIS-30 east Madison)
Cambridge (?) (I-39/90 at US 12/18)

What interchanges do you know have names mentioned (media, official, whatever)

IMHO, formal names make it much easier to identify major interchanges when discussing them with highway guys as well as the public at large.

Anyways, Wisconsin has named interchanges all over, many official, many others unofficial.

The last one that you mention is the Beltline interchange.

Also, the Zoo Interchange is in the City of Milwaukee.

Others:
-I-94/WI 119 - 'Airport'

-I-39/43/90 - ('Beloit'*)
-I-90/94/US 12 in Lake Delton - ('Lake Delton'*)

Other freeway-to-freeway interchanges in Wisconsin that are, to the best of my knowledge, not yet named:

One that was named, but no longer needs its name:
-US 61/151 'Sandy Hook' interchange between Dubuque, IA and Dickeyville, WI - name became obsolete when major new Mississippi River bridge was completed in 1980s.

-I-94/WI 35 (east split) in Hudson
-I-94/US 53 in Eau Claire ('Altoona'?)

1. East Towne (media reference)

A few in the Los Angeles area:

The "Orange Crush" where I-5, California 57 and California 22 meet

The "Kellogg Interchange" where I-10, California 57 and California 71 meet

The "Newhall Interchange" where I-5, I-210 and California 14 all tie into each other

[SidS1045]

Does southern California still have the "Slauson cut-off" (for those of you who remember Johnny Carson as Art Fern)?

[Special K]

The I-35/80 systems interchanges in Des Moines: The East and West Mixmasters.

[deathtopumpkins]

In addition to the previously mentioned Braintree Split (which lately I always hear referred to as just "the Split" on radio traffic reports), MA also has the South Bay Interchange where I-90/MassPike meets I-93, though this name doesn't see anywhere near as widespread of usage.

I've always thought out of the cities I've been to, Boston has the most confusing traffic reporting nomenclature. For example, a common backup on I-93 southbound leaving the city in the evening is referred to along the lines of "The Expressway south's jammed from the O'Neil Tunnel to the Split".

The MassPike, unlike previously mentioned toll roads, doesn't have named interchanges, though they are occasionally referred to by the town they serve, like I hear "the Palmer exit" for Exit 8, or "the East Boston interchange" for the end of I-90 at MA 1A.

[HighwayMaster]

Does southern California still have the "Slauson cut-off" (for those of you who remember Johnny Carson as Art Fern)?

Yes, it's the 90 freeway from the 405 north of LAX.

Don't forget about the Eisenhower Interchange in Harrisburg, PA (I-83/I-283/US-322).

I'm also surprised that no one has mentioned Akron's Central Interchange (I-76/I-77/OH-8) yet.

[Zmapper]

Colorado has three named interchanges, but only one is commonly known.

• I-25/I-70 - Mousetrap
• I-25/I-225 - Full House
• I-25/I-76/I-270/US-36/70th Ave - Turnpike Tangle

And to top it off, I hereby designate the former full-cloverleaf I-25/US 34 interchange as the... drumroll please... McWhinney Mistake!
