Local naming conventions for long multiplexes

[OCGuy81]

I know from when I used to visit Houston a lot for work, that the multiplex of I-10/US 90 was generally referred to as the Katy Freeway. (90 is invisible through most of this)

[SEWIGuy]

I don't know about today. I lived in Madison in the late 70's. We'd refer to the I-90/94 multiplex depending on destination. If going to the Dells, it was "ninety ninety-four." When going to LaCrosse, we'd just say I-90. When going to Eau Claire or the Twin Cities, we'd just use I-94. Who knows what is used today, especially with I-39 added to the mix.

Sconsi has a limit on total miles of state maintained highways which is why it has long multiplexes like WI 32/57 between DePere and Kiel. WI 32 may be the most multiplexed highway in the state with concurrencies of US 45, WI 55, US 8, WI 64, WI 22, WI 29, I-41, WI 57, US 151, and I-43.

I stand by my claim that WI-32 would be one of the most agonizing state routes to clinch in the nation. At least 8 hours of driving, a large chunk of which is stop-and-go city driving in Green Bay, Milwaukee, Racine, and Kenosha. Then you finally get to the IL or MI border thinking you've clinched it, only to realize you made a wrong turn at one of the three dozen street changes on the route.

I just clinched it last week by taking it from Pulaski to the Three Lakes area.  I hadn't been on many of the "stand alone" segments.  Only the duplexed ones.

Anyway, I-894 in the Milwaukee area is known as I-894 despite the duplexes with I-41 and I-43.

Yep! I remember that when I grew up in SE Wisconsin.  Even once 43 was routed along there when it was extended to Beloit, that part still remained 894.

US 15/501 in north carolina is signed as such along most of its 100 mile duplex

And they call it "fifteen-five-oh-one".

[-- US 175 --]

The predominant amount of people (including traffic reporters) call the US 81-US 287 overlap from north Fort Worth to Bowie, as 287.  US 81 might as well not exist south of Bowie.

As for the US 87-US 287 overlap between Amarillo and Dumas, it seems to be a mixed bag.  IIRR, "287" seems to edge out any of the other ways in which it could be referred.

The ads for Choctaw Casino south of Durant only refer to the US 69-US 75 overlap in front of their complex as "Hwy. 75".

[US 89]

As for the US 87-US 287 overlap between Amarillo and Dumas, it seems to be a mixed bag.  IIRR, "287" seems to edge out any of the other ways in which it could be referred.

That would make sense since 287 continues straight through Dumas and maintains its four-lane all the way up to Stratford, while 87 west to Hartley is 2 or 3 lanes most of the way. The concurrency is even signed "HWY 287" on street signs.

MN:

I-94/694 - both if referring to that segment, or just 94 if referring to the greater part of the route

I have never heard anybody refer to it using both numbers. It's just 694, unless you are continuing on 94 at either end, in which case it's probably 94.

[plain]

• US 1 and US 9 in New Jersey

Either "One 'N Nine" like jeffandnicole said, or "One Nine"

• I-64 and I-77 in West Virginia

"Seven-deh-seven" or just "The Turnpike"

• I-80 and I-90 in Indiana and western Ohio

"Eighty Ninety"

You beat me to it 

[SkyPesos]

• I-80 and I-90 in Indiana and western Ohio

"Eighty Ninety"

I rarely hear I-80/90 called with both numbers, or even with numbers at all. It's either Indiana Toll Rd in Indiana or Ohio Turnpike (or just Turnpike) in Ohio.

[hbelkins]

I'm curious as to what locals call the section of freeway north of Asheville that carries four US routes (19, 23, 25, and 70) along with Future I-26.

• I-80 and I-90 in Indiana and western Ohio

"Eighty Ninety"

I rarely hear I-80/90 called with both numbers, or even with numbers at all. It's either Indiana Toll Rd in Indiana or Ohio Turnpike (or just Turnpike) in Ohio.

I've heard truck/delivery drivers call it that in the Toledo area (also just Turnpike)

[Dirt Roads]

• I-64 and I-77 in West Virginia

"Seven-deh-seven" or just "The Turnpike"

Except for the section through Charleston.  Back when I romped those parts, that was called either "I-64 through the back side of Charleston" or "I-64 behind the Capitol" with no reference to I-77 whatsoever.  Some of the older folks still called it "the road through the Triangle District".  Yet in those days, I-64 wasn't truly multiplexed down the Turnpike until the completion of the Sam Black Church extension in 1988.

I haven't heard a radio traffic report in Charleston in years.  Wonder how they refer to that section now?

[frankenroad]

I will often hear the I-71/I-75 concurrency in Kentucky referred to as "71-75" on WKRC traffic reports.

Most traffic reporters in the Cincinnati area are pretty good about calling it 71/75, but most of the general public usually just calls it 75.

Other concurrencies in our area:

I-74/US-52 - people refer to it simply as 74 (sometimes including ODOT - they don't always bother to include US-52 in the signage).

Another long concurrency in our area is US-22/OH-3.  Most people just call it by its various names, i.e., Gilbert Avenue, Montgomery Rd, 3-C Highway. 

[NWI_Irish96]

In Indianapolis, 465/74/31/36/52/37/67/421 is just referred to as 465.

[rower155]

Who knows what is used today, especially with I-39 added to the mix.

In southern WI, it is most commonly referred to as I-39 today.

[bdmoss88]

Idk about the residents themselves, but the Alabama DOT seems to treat the I-20/59 overlap as I-59. The 3di to Tuscaloosa is x59 rather than x20, and on the official state map which features "straight line" type maps of the Interstates with ramp configuration diagrams for each interchange, I-59 gets one continuous map while I-20 gets a "see I-59" when reaching their merge point.

It's generally called "fifty-nine twenty".

For Massachusetts...

I-95/MA 128, still called 128 generally by people
I-93/Not MA 128 anymore, still called 128 by the media, but not as much by people as the 95/128 stretch
MA 4/MA 225, called by both numbers
US 5/MA 10, a mix of both or just 5

As stated above, any overlap with US 202 is called by whatever the other route is (MA 2, MA 10)

New Hampshire has the lengthy US 202/NH 9 multiplex, joined with US 4 for a long stretch as well. I've generally heard the 202/9 stretch called as 9, and the 4/202/9 stretch called as 4. Guess 202 gets the same treatment in NH as well. That should say something about its importance.

[DandyDan]

US 6 and US 34 in Nebraska is called 6-34, at least by my brother and sister-in-law.

[Some one]

I-69/US 59 in Houston is locally referred to as "59". You're hard-pressed to find anyone outside of outsiders, news media, and roadgeeks actually refer to it as "I-69"

• I-80 and I-90 in Indiana and western Ohio

"Eighty Ninety"

I rarely hear I-80/90 called with both numbers, or even with numbers at all. It's either Indiana Toll Rd in Indiana or Ohio Turnpike (or just Turnpike) in Ohio.

I never hear it called 80/90. Like you said either Indiana Toll Road or Ohio Turnpike. Once 80 gets to the Borman though I've heard people call that 80/94.

I never hear it called 80/90. Like you said either Indiana Toll Road or Ohio Turnpike. Once 80 gets to the Borman though I've heard people call that 80/94.

I would say about 50% call it the Borman, 40% 80/94, and 10% just 80.

75-85 in Atlanta, or the Downtown Connector. Actually, the Downtown Connector is only north of I-20, but very few people realize that.

[SkyPesos]

Actually, the Downtown Connector is only north of I-20, but very few people realize that.

Seems like the Wikipedia article on it is incorrect too then:

In Downtown Atlanta, the Downtown Connector or 75/85 (pronounced "seventy-five eighty-five") is the concurrent section of Interstate 75 and Interstate 85 through the core of the city. Beginning at the I-85/Langford Parkway interchange, the Downtown Connector runs generally due north, meeting the west—east I-20 in the middle. Just north of this is the Grady Curve around Grady Memorial Hospital. Continuing north, the terminus of the Downtown Connector is the Brookwood Interchange or Brookwood Split in the Brookwood area of the city. The overall length of the Downtown Connector is approximately 7.5 miles (12 km).

Wiki is wrong about lots of stuff, and then the out-of-area people who wrote the incorrect information get all butthurt when someone local fixes it.
