Concurrencies commonly called by both numbers

[Jim]

The first that came to mind for me is "9 and 20" east of Albany.

[ilpt4u]

Any Wisconsinites want to contribute, whether I-90/94/39 between Madison and Portage, and then I-90/94 until Tomah, is locally designated as?

I've never really heard I-39/US 51 in IL called by both, nor I-90/I-39 -- thats still the Northwest/Jane Addams Tollway

I-90/94 in Chicago is commonly known as the Dan Ryan Expressway (south of the Jane Byrne Circle Interchange) and (JF)Kennedy Expressway (north of the Jane Byrne Circle), not by route numbers, anyway

[Sam]

In the Finger Lakes I'm pretty sure they called it "5 & 20", even though it's rightfully signed "20 & 5" (US 20 and NY 5).

Yep. Always "5 and 20". Is the concurrency in Erie and Chautauqua counties also called "5 and 20" ?

[jp the roadgeek]

I'm sure many call the long southern concurrency I-20/59
Another one is "Route 6 and 44" through Manchester, CT

I can think of 2 concurrencies that are never called by both numbers (except by a tourist): US 5/CT 15 (most call it the Berlin Turnpike or Route 15), and I-95/MA 128 (any Bostonian will self-destruct if you refer to it by the former).

[US 89]

Most concurrencies are referred to by one number only in Utah:
I-15/80 and I-15/84 are just I-15.
40/189 and 40/191 are just US 40 (189 is actually unsigned there)
6/89 and 6/191 are just US 6
Anything with an Interstate and a US is always just the Interstate
Exceptions:  89/91 and western 6/50.

In CO, US 6/24. 24 has been truncated, but there are still some signs hanging around on business addresses and on a few town street signs. Google names the Main Street of Glenwood Springs as "Hwy 6 & 24".

[ilpt4u]

Thought of I-290 and IL 53 in the Schaumburg area -- its not usually called both numbers at the same time, but is often referred to Route 53 or I-290 or even Ike Extension (tho that is more proper to the "diagonal" segment between I-88/I-294 and I-355)

[DandyDan]

In Nebraska, I knew someone who referred to what is now US 75 south of Omaha as US 73/75, even though that concurrency ended in the 80's.  I believe there is 73/75 Storage in Plattsmouth still.

[cbeach40]

In Ontario, Highways 7/8 and 35/115 tend to get both numbers mentioned. More so with the former. Most other overlaps either have one dominant route (eg, Hwy 403/24), or are known by another name in that particular area (eg, Thunder Bay Expwy, aka Hwy 11/17).

[DeaconG]

US 17/92/441 (Orange Blossom Trail) in the Orlando area is often referred to as "17/92".

[theline]

I-35/80 in the Des Moines area is often referred to as "80/35." There's even a music festival that goes by that name.

Correct me if I'm wrong, but I think the outer bypass of Des Moines is referred to as "65/5", despite the concurrency itself being only a mile or two.

Also, there's I-80/94 in Northwest Indiana

Yes, and there's 80/90 as well.  Both also have names that get used 80/94 is "The Borman", and 80/90 is the "Indiana Toll Road" and "Ohio Turnpike".  However, on Chicago radio, 80/94 is usually called that, and 80/90 is "The Toll Road" or "Indiana Toll Road".

As a South Bend resident and frequent visitor to the Region, I can confirm that you're right about both the Borman and the Toll Road. Both are generally referred to by their names rather than numbers by locals. One occasionally hears the Borman called by one of it's numbers, but almost never by both.

In South Bend, we always know when advertising copy has been written by outsiders, when it refers to something being "just off I-80" (or I-90 or I-80/90), rather than the Toll Road.

A very long time ago (over 35 years), I read a newspaper article that I think was about a trend, at the time, of people posting public apologies for road-rage behaviors (!).  The example was given was out of Chicago, where a woman wrote that she was really sorry about what she did on "80-90-94" the other day.  Was there ever a time when all 3 routes were on the same highway?  Note that it was not a Chicago newspaper where I read this.

I would be very surprised to hear that 80, 90, and 94 ever shared the same pavement. I've never seen a map that showed that, and I've been studying Chicagoland maps for nearly 60 years.

The big ones in New York (all mentioned previously) are:

US 20/NY 5 ("5 and 20"). This mainly applies to the long concurrency in the Finger Lakes, not the short one in Irving.
US 44/NY 55 ("44 55"). I have NEVER heard this by another name.
NY 106/NY 107 ("106 107"). It's worth noting that these are some of the ONLY roads on LI frequently referred to by number.
US 9/US 20 ("9 and 20"). Occasionally called by name.

Other ones I have heard at least once, but not often:
US 4/NY 32 ("4 and 32")
US 6/US 202 ("6 and 202")

In Idaho Springs, Colorado, there's the "6 & 40 Motel", named for the respective US routes.  Not sure if that's what the road was referred to, though. 

You are correct about US-6/US-40 running through Idaho Springs.

Other multiplexed road names which are referred to as such in Colorado:

-  "Highway 6 & 24" -- pretty much what's left of the old highway in Glenwood Springs -- despite US-24 being long truncated back to the Minturn/Vail area, US-6 technically still runs along that road.

-  "Highway 6 & 50" -- runs from just west of downtown Grand Junction to the Utah line on the pre-I-70 alignment of US 6.  Some areas along this highway drop the "50" on their addresses as US-50 West "technically" ends at BL-70 in downtown GJ as far as CDOT is concerned.

CDOT does not like to sign/denote multiplexed routes on BL-70, nor along vast stretches of US-6/US-50 which parallel I-70 in Colorado, hence the "technicality".

[Darkchylde]

I've heard "Along the old 71 Highway or the new I-49" in radio ads in Kansas City for a business or two along that stretch in Grandview.

Typically, it's not called something like "49 and 71" by most, but it is interchangeably known by both numbers.

[Avalanchez71]

US 31A and US 41A have a concurrency in Williamson County going into Metro Nashville/Davidson County.  In the southern portion many call the route 31/41 without the A.

[amroad17]

In the Finger Lakes I'm pretty sure they called it "5 & 20", even though it's rightfully signed "20 & 5" (US 20 and NY 5).

Come to think of it, you are correct.  The locals do say 5 and 20.

[6a]

US 36 & SR 37 in Ohio (at least the exit with I-71) is called 36/37

[RobbieL2415]

Do New Jerseyans call US 1-9 "US 1-9"?

[RG407]

US 17/92/441 (Orange Blossom Trail) in the Orlando area is often referred to as "17/92".

Street signs in Seminole County even say "US 17-92."  I think that's also the case in Volusia County.

Locals usually refer to US 441 in the Orlando area as Orange Blossom Trail or OBT, including the section with the 3-way concurrency with 17-92.

[US 89]

I remember seeing a few signs/businesses on US 17 between Georgetown and Charleston SC with US 17/701, and it may still occasionally be referred to as such. According to usends.com, US 701 was truncated to Georgetown in 1992, although it had been a useless multiplex with 17 since 1935.

I-80/90 through IN and OH.
I-65/70 in downtown Indy

[theline]

I-80/90 through IN and OH.

Prior posts claim otherwise, if we stick to common usage (emphasis added; irrelevant quotes removed):

Also, there's I-80/94 in Northwest Indiana

Yes, and there's 80/90 as well.  Both also have names that get used 80/94 is "The Borman", and 80/90 is the "Indiana Toll Road" and "Ohio Turnpike".  However, on Chicago radio, 80/94 is usually called that, and 80/90 is "The Toll Road" or "Indiana Toll Road".

Both are generally referred to by their names rather than numbers by locals. One occasionally hears the Borman called by one of it's numbers, but almost never by both.

In South Bend, we always know when advertising copy has been written by outsiders, when it refers to something being "just off I-80" (or I-90 or I-80/90), rather than the Toll Road.

US 20/26 through Boise is typically referred to as such when it is not referred to by the local street name.

I can confirm, and I came here to say this. However, probably 80% (or more) of the time you'll hear just "Chinden" for the segment west of downtown Boise (which is actually quite well signed through all of Ada County, all the way up to Can-Ada Rd. at the county line). It doesn't take on this name in Canyon County at all (most signs I can see on GSV say "Hwy 20/26" or similar, and there doesn't seem to be any local name until Aviation Way in Caldwell, where you can pretty clearly see the cutoff), though people would probably know what you're talking about if you said it. The Canyon County segments (both east and especially west of Caldwell) are where you're most likely to hear the route numbers used.

Broadway, Front, and Myrtle Streets, in addition the the freeway segment in west downtown ("The Connector"), you'll never hear route numbers there (though they are signed decently well).

When I was a kid, US-29 and US-211 ran together through Northern Virginia and it was common to hear people refer to "29/211," but since 211 was truncated to Warrenton that habit fell by the wayside years ago.

I've heard some people refer to the segment of US 29 between Warrenton and DC as 29/211 long after US 211 was truncated, though not recently.

I've heard the US-15/US-29 concurrency between Culpeper and Gainesville referred to as 15/29 several times. Also, although less frequently, I've heard 29/211 referenced as well.  Interestingly enough however, I don't believe many refer to the US-15/US-17/US-29 concurrency between Opal and Warrenton as 15/17/29. Either for some reason people think US-17 ends/begins in Opal or maybe its just too hard to say 15/17/29.

U.S. 85-87 leave I-25 and go through the suburbs south of Colorado Springs. The street name is "Highway 85-87". Thing is, only U.S. 85 is posted by the state.
