Multiplex pairs

[Alps]

In downtown Columbia, SC, US 21/321 are multiplexed with US 76/176. Is there anywhere else in the country where two pairs of routes like that are multiplexed?

[NE2]

US 1-US 301 and US 23-GA 23

[jp the roadgeek]

I-74 and US 74

[NE2]

I-74 and US 74

Mine's closer.

Madison Wisconsin has US 18 and 151 join the Belt Line that is already carrying US 12 and 14 at the Verona Rd exit.

[Coelacanth]

Technically speaking, US 10/61 is multiplexed with I-94/US 12 in St. Paul.

However, only I-94 is signed along this stretch.

[NE2]

Missing the point.

Steve's looking more for two sets of parent/child routes that are together.  As a fictional example, I-95 and I-495 with US-1 and US-301 type thing.  I don't know of any like that in the Midwest offhand.

I think it's rare enough that a child multiplexes with a parent.  To have two such pairs multiplex with each other... rare duck indeed.

Missing the point.

Yes, you're so clever, turning NE2's favorite word against him... after Brandon was already kind enough to explain the point.

Closest one in Midwest/South I can think of is US 71, US 371, and US 59 is SW Arkansas. US 259 is only 24 miles west of these highways.

Alanish, motherfucker.  Do you speak it?

Now there's a mushroom cloud layin' multiplexin' motherfucker, motherfucker.

Almost: US 1-301 and US 60-360 duplexes are very close to one another but not on the same road.
Not quite almost:  US 1-401 and US 64-264 in the same metro area

I'd argue I-70/US-50 and US-6/191 between Exits 157 and 182 (Crescent Junction) in eastern Utah, though US-191 splits off on its own at Crescent Junction.

See, the problem is when I ask questions, I tend to ask things that aren't immediately obvious, which just tends to befuddle the unwashed masses

That may have well been Steve's point but that was not how he worded it in his example in Columbia. The way I interpreted the question had to do with a multiplex route JOINING another multiplex route. Nothing about parent routes was in his original post aside from the number examples he used. He did not specify a parent routing.

So for those of you wanting to jump down my throat for something that I was quite correct in pointing out and reading his post the way he worded it, pardon my attitude when I say to you "Screw you".

Play nice. Your error was pointed out. Accept it and move on.

Waycross, GA has one.  US 1 & 23 duplex with US 82 & GA 520. 

Now some may say GA 520 is a secret route as all US highways in GA have state route numbers assigned and signed with them, but GA 520 is Corridor Z and is not as silent as the other secret numbers.  It forms a well established corridor from Columbus and across South Georgia to Jekyll Island and is even independent in Western Georgia from any US routes for several miles.

So in retrospect it is two pairs of concurrencies together that run for miles on each end separately.

US 60/70 and US 80/89 met at Florence Junction AZ before making a quadruplex through Phoenix.

You all still don't get it. Steve's looking for two pairs of parent-child routes.

Does the 31-431-70-70S intersection in Nashville count?  Not really a multiplex, as all four routes only meet at that intersection.

Otherwise, all I can come up with are near misses.  Like 65-165 & 67-167 in Little Rock -- close, but not quite.

My gut feeling is that Steve came up with the only example of this kind of multiplex pair in the OP.

I've been in Nashville twice (in 2006) and I recall some crazy concurrencies there, i.e. 70S/70.

Having said that, I am not sure if 41A is concurrent with 41 on 8th Street, where 31 and 431 run together as well.

Vincennes, IN, is lacking a US 741 to go with US 41/50/150

In days of Ohio yore (pre-interstate), you had the US-21/SR-14/SR-43 multiplex multiplexed with the US-422/SR-8/SR-87 multiplex heading south out of Cleveland's Public Square along Ontario St. for about a mile or so.
