highest number of multiplexes

[pianocello]

I saw on wikipedia once a picture of 4 interstate numbers (TO I-44-55-64-70) on one shield in St. Louis, but I can't seem to find it now. IIRC, there's also another 4-number shield around Museum Campus in Chicago (TO I-90-94-55-290), but don't quote me on that.

Yeah, there's our newer black state highway signs. I liked the old green ones better.

Agreed.

Random question: does Louisiana still use the narrow 2-digit sized route shields for 3/4 digit routes? Or do they use wider 3-digit sized shields for those?

Yes for a lot of them. they squeeze 4 digits with the same narrow numbers. I'm pretty sure that sometimes the "toe of the boot" of the Louisiana shape are extended longer on signs, but probably only on some older green state signs. I think there are some on the Inner Loop Expwy, LA 3132 in Shreveport, but I don't have pictures.

on the other hand US400 in Kansas is really a redundant number.  Something like 80-90% of the route is doubled with another US route

[route56]

The only two in Kansas I can think of with more than three are I-35/U.S. 50-56-169 for a while from Olathe to I-435 and the very brief I-135/U.S. 81/K-15-96 one in Wichita.

Okay, three. I-70/U.S. 24-75/K-4 for a bit in Topeka.

*gibbsslap*

It's I-70, US *40*, K-4, and US 75 in Topeka

Thanks to the turning back of State Ave, we do have K-7/US 73/US 24/US 40 (of which KDOT gave K-7 top billing on most of the signage), I-70/US 24-40-69, and I-70/US 24-40-169

Can't think of anything else attm.

The highest in Chicagoland is I-80/I-94/US-6/US-41 in Hammond, IN

The most you'll see in Oregon is 3 multiplexed routes, which occurs in three different locations (I-205 & OR 213/224, I-84 & US 30/395, and US 20/26 & OR 201).

So are Oregon 99 and US-30 not considered concurrent with I-5 and I-84, respectively? I know they aren't signed, but I assumed a hidden concurrency did exist.

The I-84 and US-30 concurrency is rather well-signed, whereas the I-5 and OR-99 concurrency is only implied and very rarely signed, except for the concurrency with 99E near Salem.

They are, but with the exception of the 84/30/395 I mentioned, that doesn't affect any other triple concurrencies.  Oregon has plenty of duplexes; I was only listing the triplexes.

The I-84 and US-30 concurrency is rather well-signed, whereas the I-5 and OR-99 concurrency is only implied and very rarely signed, except for the concurrency with 99E near Salem.

The only places I know of where the I-5/OR 99 concurrency is acknowledged is on BGS's on a couple on-ramps: as northbound 99 merges onto I-5 in north Grants Pass:



and where southbound 99 merges onto 5 in Eugene (which I don't seem to have a pic of, but here's the StreetView):

There might be other locations I can't recall, though.

Thanks for sharing! I like that style the best.

And that's in Indiana.  Nothing in Illinois around the area is its equal.  You have to go down to Metro East to find that many routes on one road.  I-55, 64, 70, and US-40 share a short stretch from Missouri to Exit 3, and IIRC, IL-3 is mixed in there as well.

IL 3 does indeed multiplex with I-55/64/70 from the PSB Complex to the Tri-Level.  You could also throw in the Great River Road.  This section will be losing I-70 in a few years when the Great Lemon opens, and IL 3 sometime down the road when the new alignment that stays separate from I-55 opens.

This particular area of roadway has had a lot of multiplexed routes in the past also, with I-55/70, US 40-50-66 for a few years, then I-55/70, US 40-50, and IL 3 for a few more years before US 50 was relocated to I-255.

84/30/395 is neat because there is only one standalone reassurance shield (total, for both directions) for all three routes


Mostly they just post these under all the overpasses




Although there are 2 standalones that just acknowledge 84 and 395



and one right after the 395 junction that omits US-395

here is one with five digits and a hyphen

[huskeroadgeek]

Nebraska never has any more than 3 concurrent routes. If I count correctly, there are 6 such instances: I-129/US 20/US 75 in South Sioux City, US 77/US 275/NE 91 N. of Fremont, US 6/US 34/US 281 in Hastings, US 6/US 34/NE 44 W. of Minden, US 6/US 34/US 83 at McCook, and US 26/NE 71/NE 92 at Scottsbluff.

Are there any examples in which 84/30 share the same cardinal direction legend on a BGS?

Jeez, those are hideous!  It's almost as if the US route shields in the design were an afterthought after the sign blank had been ordered. Surely those could have been designed a bit better...

[roadfro]

Highest number of overlapping routes you'll find in Nevada is three. There are two instances, with a third in the works someday.

1) I-515/US 93/US 95 - from downtown Las Vegas to Railroad Pass (between Henderson and Boulder City) - about 20 miles.

2) US 6/US 50/US 93 - from Ely southeasterly to Major's Junction - about 26 miles.

3) FUTURE: I-580/US 50/US 395 - Carson City Bypass - about 4-5 miles. This future one is contingent upon completion of the final 3-4 miles of the bypass (still a few years away due to lack of funding) and subsequent extension of I-580 down from Reno.

They aren't all shown on reassurance markers, or trailblazers, but I believe the intersection with the most (or it not the most, definitely a great number) of concurrencies, at least in the Orlando, FL area, is this one: 28.304454N,81.403685W. Including the hidden state road designations, there's US 17, US 92, US 192, US 441, SR 500, SR 530, and SR 600 - 7 different designations. The only other one that comes close is when US 17/92/441 meet SR 50 in downtown Orlando with 6 different designations.

[corco]

Are there any examples in which 84/30 share the same cardinal direction legend on a BGS?

Yes, where they choose to sign 84 and 30 on BGSes and no other routes are concurrent (they mostly only sign I-84 on BGSes, omitting US-30). Heading eastbound there are exactly 6, 5 of which are in the Portland area. Those 84 East/30 E signs are exclusive to the 84/30/395 concurrency

Jeez, those are hideous!  It's almost as if the US route shields in the design were an afterthought after the sign blank had been ordered. Surely those could have been designed a bit better...

I actually kind of like them- the spacing is a bit weird, but the idea seems fine

[bassoon1986]

ooh found another one - I-55 crossing the MS river from Memphis to Arkansas. I'm curious as to where this is. Is it westbound Crump Blvd? And are there stand alone signs of all 5?

and some in Chattanooga. Only 4 though (US 11, 41, 64, 72)

Wyoming has a few quadraplexes, my favorites being the business loops and parallel mainlines that are fully signed. Example, Douglas:
