Multipexes that are only refered by only one route number

[Interstate Trav]

In Downtown Los Angeles when the 10 and 5 multiplex for a couple of miles, the 10 isn't even signed.  It's almost as if the 10 vanishes for 2 miles.

Technically, it does. Legislatively, it 'ends' at the East LA Interchange at I-5 and 'begins' at US 101 at the western terminus of the San Bernardino Freeway.

Oregon: The I-5/OR 99 or I-5/OR99E duplexes are all effectively I-5. The I-5/US 30 and I-405/US 30 duplexes effectively don't exist, though they'll be signed on maps. I-84/US30(/US395) are I-84, or the Banfield in Portland.
I suspect the I-84/US20/26/30 quadplex in Idaho is just I-84...

US 151/IA 13 in the Cedar Rapids area is referred to just as "Highway 13" by locals.

You'd never know CR 536 follows US 322 in SW New Jersey from talking to people, but it's on all the signs. (In that part of the state, county routes DO get recognition by number, so it's fair.)

Don't ever tell anyone in NJ that I-95 follows The Turnpike. "I'm taking I-95 into New York." "From the Turnpike?" The only way that anyone knows 95 is on the Turnpike is when you bring up there being two 95s in NJ, and then they seem to forget the next minute.

An inverse case, 38/70 - Not a concurrency, but everyone thinks it is. For a good mile, it's just NJ 38 between 70 and US 30. I could be wrong, but I also think that the adjacent 30/130 concurrency is just known as Route 130.

I-87/287 - Perhaps because of how long it took to get to NJ, most people don't recognize 287 along this stretch. I-287 in NY is strictly the Cross-Westchester. I think 287/17 at the I-87 interchange is even just referred to as 17, such that you might say to take 287 to 17 to get to the Thruway.

On street signs, U.S. 23/S.R. 42 -- in Clayton and Henry counties (Ga.) -- is just referred to as S.R. 42, or Hwy. 42.


Be well,

Near me, US 206 multiplexes with NJ 94 through my town, but its just referred to as "206."
The I-295 and US 130 multiplex in Gloucester County is referred to as 295.

[wh15395]

The Interstate 465 beltway around Indianapolis is always called 465, or I-465, no mention of I-74 that follows it around the south and west legs and there will probably be no reference to I-69 when it is multiplexed around the highway as well. When you refer to I-74 it's always the part outside the 465 beltway.

That's true for locals, but what's weird is on my GPS, it refers to the South Side of 465 as I-74, not 465.

[WillWeaverRVA]

The I-95/I-64 concurrency in Richmond is universally referred to as "95" or "I-95". Which makes sense as I-64's mileposts are effectively "silent"; the concurrency uses I-95's mileage, mileposts, and exit numbering.

The only combined reassurance marker on the route itself (there are plenty of combined trailblazers on surface streets) is on I-95 NB/I-64 WB just north of US 1/301, which itself is only referred to by either the names of its streets (Chamberlayne, Belvidere, Jefferson Davis, etc) or "301". There is one I-95/I-64 pull-through sign SB near VA 161.

Other than the 80/580 concurrency, co-signed routes rarely ever are acknowledged in the Bay Area:

880/84 in Hayward
101/84 in Redwood City
101/1 on the Golden Gate Bridge
280/1 in Daly City
280/35 from San Bruno to San Mateo

It doesn't exist anymore, but the old 680/24 concurrency between Walnut Creek and Pleasant Hill likely falls in this category as well.

In Sacramento, the section of Business 80/Capital City Freeway that is concurrent with US 50 is always referred to as "US 50" by locals and by traffic reporters.  The 99 concurrency on 50 and 5 isn't noted much.

[agentsteel53]

those sections of CA-1 which are multiplexed with US-101 are done so quite silently.  except in Ventura, where there are some green signs that reference both route numbers, I cannot think of any examples of the multiplex being signed.

Just north of the Golden Gate Bridge, there are a few 101/1 trailblazers.  Santa Barbara is the worst offender at not acknowledging 1 at all though.

I want to say the area around San Luis Obispo/Pismo Beach is a little better for 101/1 signing.

US 41/64/72 from Jasper to Chattanooga,TN. Locals just call it "Highway 41".

US 81/287 from Fort Worth to Bowie, TX. Locals refer to it as "287". Interesting considering that the 81 signs are on top (because there the smaller number), and a long time ago this was just US 81, and 287 was added to it later in history. It does, however, make sense from a logical standpoint. This is because US 287 is the more important highway, remaining a heavily traveled divided highway to Amarillo and beyond, while US 81 splits off and becomes a much-less important two alne road servicing only smaller towns in Oklahoma.

am I the only one who thinks of US-81 as being a very important highway?  I always consider it to be the dividing line between "east" and "west" in the United States, and whenever I cross US-81 I note this fact - as opposed to, say, 83 or 77.

for that reason, I am sad that it no longer exists under I-35 to Laredo.

I've noticed that the humidity feels like it jumps around 50 percentage points every time I cross US-81 heading east, no matter where I am in the country. So yeah, I agree

I-287 isn't mentioned on this pull through just west of the Tappan Zee Bridge:

How about the NJ Turnpike's Newark Bay Extension not ever being called I-78?  Most New Jersyans think the eastern terminus for I-78 is at I-95.  That is why no one ever puts pressure on NJDOT to have I-78 truncated to the end of the Turnpike Extension in Jersey City!  Most people think that 12th and 14th Streets in Jersey City are US 1 & 9 instead of I-78 violating interstate guidelines.

[sandiaman]

Here  in New Mexico,  US  491,  aka  US  666,  was  known  as the Devil's  highway  , not only due to  the   Biblical number  but also    due to the high  amount of horrendous    alcohol related  accidents.  Our  superstitious  governor, Bill Richardson had the number changed  from 666  to 491.  Has  it helped?

I strongly dispute that. People do call it the Turnpike, but they also call it 78 now. People have stopped referring to it as 1/9, they sorta realize you take 1/9 TO the tunnel but they don't really know what the other road is. ("Covered roadway" is the most popular reference.)

Bryant: These signs are not an unusual sight in New York. I think they're neat. My theory is that they made them that way to reduce wind drag.

my guess is that it is to save the costs of the raw materials.

I guess I'd never really thought about it that way, but it does kind of represent a good east/west dividing line. In Nebraska though, the dividing line is usually thought of as being further west-the 100th Meridian has traditionally been thought of as the E-W dividing line. For a good reference point on I-80, the 100th Meridian runs right through Cozad(NE 21 running into town from I-80 is called Meridian Ave.)

SR 8 and SR 59 in Akron and Cuyahoga Falls. When SR 59 joins SR 8, the multiplex section is referred only as "Route 8."

Of course, it's helped that until fairly recently, ODOT barely acknowledged that OH 59 shared the route.

I-265 and KY 841, the Gene Synder Freeway, referred to as 841.

I generally refer to is simply as I-265, but then again, I'm not local to Louisville.

I-76/277 and US 224 in the Lodi/Akron area - many locals, 50 years after the I-76 portion became an interstate and pushing 40 years after it became I-76 (it was I-80S), many locals still call it Route 224.

Hmm, I guess I hung out with different people.  During my 10 years in Akron, I always heard it referred to as I-76 only.  I know I do.

I never heard that before, to me, the east/west dividing line is the Mississippi River.  Of course, as I am also a railfan, it is generally true.  Even today, the western railroads (BNSF, UP) only make small forays east of the river and the eastern roads (CSX, NS) rarely go west of it.

US 50 from MD Eastern Shore to DC is just called "50" even though there is US 301, I-595 and MD 2.

Can't really count I-595 since it's a hidden route, even with the open space for shields on just about every guide sign between the Beltway and Annapolis.

But it's curious to note the lack of US 301 shields on many of the guide signs.
