In Indianapolis, a small section of I-465 is multiplexed with I-74; U.S. highways 31, 36, 40 and 52; and Indiana 37, for a total of seven highways! Are there any multiplexes with as many highways on them?
Probably somewhere in Georgia there is...
California's biggest multiplex (both signed and unsigned) is just five miles from me here in Sacramento, on the WX segment of the Capital City Freeway (between I-5 and Route 99) -
US 50
Business 80
Route 99
unsigned I-305
Technically, one could also argue that Route 16 runs through here unsigned as well...
The Jackson area has a five-highway multiplex: I-20 & I-55, U.S. 49 & 51 and Mississippi 18 (though 18 is not signed as much).
You missed one, golden eagle; there's also US-421, making that an octuplex (8 way concurrency).
From the misc.transport.road FAQ (http://www.roadfan.com/mtrfaq.html)...
Q: Which highway has the most multiplexed routes?
A: I-465 on the east side of Indianapolis, IN, between the US-36/SR-67 and US-40 exits, also carries US-31, US-36, US-40, US-52, US-421, SR-37, and SR-67, for a total of 8 routes on one highway, though only I-465 is posted along this stretch as all other routes following I-465 except I-74 have a sign reading "FOR [route shield][direction]/FOLLOW [I-465 shield]/to Exit [number]" on the onramps where they enter I-465 (see http://illi-indi.com/showFull.php?id=1452§ion=34652 (http://illi-indi.com/showFull.php?id=1452§ion=34652) ). The most signposted routes is 7 in GA: US-1, US-23, US-301, SR-4, SR-15, SR-23, and SR-121 just short of the FL line ( http://www.gribblenation.com/papics/outofstate/gatotempole-folkston.jpg (http://www.gribblenation.com/papics/outofstate/gatotempole-folkston.jpg) ). This is possible because in GA every US highway is usually paired with at least one signposted state route (see 7.6.4 ), so other examples with this many or possibly even more may exist elsewhere in the state.
I-20/59/U.S. 11/80/S.R. 19

In Greensboro, NC... the area known as "death valley" on I-40 saw the following highways: US-29, US-70, US-220, US-421 (wrong way multiplex, since moved to outer loop), I-40, and Business I-85

I-376/US 19/Truck US 19/US 22/US 30 between Exit 69A and 69C has the most multiplexed routes in Pennsylvania.

To my knowledge, Kentucky's honors go to a "fiver" in Pikeville -- US 23, US 119, US 460, KY 80 and KY 1426. All five routes are signed on a short stretch of highway south of the Pikeville Cut-Thru, but Kentucky only officially recognizes one highway on that route, US 23.
QuoteI-376/US 19/Truck US 19/US 22/US 30 between Exit 69A and 69C has the most multiplexed routes in Pennsylvania.
I do believe that general area also has the quirk where North Truck US-19 is multiplexed on the same ramp with South Truck US-19.
This is because there are no direct ramps to/from the Ft. Pitt Tunnel to/from Saw Mill Run Blvd.
Southbound Truck 19 has to take the Banksville exit, and loop back briefly onto the inbound parkway to get to S.M.R. Blvd.
Northbound Truck 19 has to take the ramp off S.M.R. Blvd towards Banksville (and the outbound Parkway), and use that same loop back to the inbound parkway.

That should say between US-40 (Washington Ave.) and US-52 (Brookville Rd.) (Exits 46 and 47), because US-40 runs with I-465 to the south of the city and thus wouldn't traverse the Pendleton Road (US-36/SR 67) interchange.

Wyoming has a ton of 4 way concurrencies- off the top of my head:
I-25 Business/I-90 Business/US-16/US-87 Business in Buffalo

I-25 Business/US-20 Business/US-26 Business/US-87 Business in Casper

Idaho is probably I-84/US-20/US-26/US-30 from Boise to Mountain Home.
Washington is stuck with a couple 3-ways, I-82/US-12/US-97 around Yakima, I-182/US-12/SR 240 in Kennewick, I-182/US-12/US-395 in Richland, and I-90/US-2/US-395 in Spokane

Signed from I-20, but not along I-20. Both MS 18 segments end at US 80, and there's no overlap with US 80.

On my wife's recent travels, she's been taking road and sign photos for me (and doing quite well, actually). I'm pretty sure she got a photo from the opposite direction at Meridian as well. I'll have to dig that out and post it. I'm still trying to sort through her Massachusetts-to-Ohio photos.
Most I can think of in West Virginia is a quadriplex, through downtown Elkins.
Here is a photo from June 2000. These old signs have since been replaced.

According to FHWA, I-44 ends at the 55/64/70 junction on the west side of the bridge.
there is a six-way multiplex in the roundabout at Boise City, Oklahoma. US-56, 64, 87, 287, 412, and state route 3. Five of the routes exit to the east (all but 87), yielding a five-way multiplex on a straight road, which is signed. I need to get photos up of the five-way reassurance gantry, as well as the six-way junction gantry approaching the traffic circle from state route 325, which ends at the circle and alas does not contribute to this already impressive situation.

Most people assume it is, but MoDOT begins posting I-44 shields on the signage high above the Mississippi approaching the I-55 exit as if it begins there. Illinois makes no mention of it. I think there's some Official Document from either MoDOT or FHWA which says it ends at the state line, but the other agency's documents contradict that.
Meridian, MS has I-20, I-59, US 80, US 11, US 45, MS 19

Also, US 45 is not part of that multiplex, having been rerouted to its own Meridian bypass back in the early 90s.
OK, I thought I saw a 45 sign when I was there last year. Guess I need to check my notes.

fear the octoplex.
The highest number of highways on a multiplex in Nevada is three, and there's two of them: I-515/US 93/US 95 in Henderson and Las Vegas, and US 6/US 50/US 93 between Ely and Major's Junction. A future three-way multiplex is planned in Carson City, once the Carson City Bypass is completed (four to five years from now?) and I-580 is extended along an ~6-mile stretch with US 395/US 50.

It would predate Coliseum Boulevard, which was the first bypass of Fort Wayne. And it should be noted that there weren't really eight designations along Jefferson at this point–the gantry merely shows that NB US 27/US 33/SR 1/SR 3 is a little farther east, although I believe at the time the photo was taken, SB US 33 did depart Jefferson onto Clinton, as it would have come into downtown via the old Lincoln Highway alignment with US 30.
December 27th, 1966.
One of the reasons why there are so many multiplexes or overlapping of highways is it saves state & federal money by putting three major highways on one road in the area instead of putting two different monnikers on two different roads for example in Fort Wayne and Indy. Also it saves numbers from being used up- That's why in Ohio you see US 250 sharing the pavement with Ohio 800. The problem, I have is Georgia where in Atlanta there are eight different routes signed on one street. I know, I know. In case the feds decide to decommission the US highway , the state could easily rename it, but is it necessary for Georgia to put up a GA 35 ends sign at the Florida state Line when drivers only refer to the highway as US 319. I don't think so.
Not counting underlying state routes, there is one quad-plex in FL. US 17/US 23/Alt US 90 (unsigned)/SR 228 share pavement for at least one block.
Most you get in Oregon are 3 highways sharing pavement, but I happen 3 times:
I-205, OR 213, OR 224 in Clackamas;
I-84, US 30, US 395 near Pendleton;
and US 20, US 26, and OR 201 in Nyssa.
Of course, just a little ways over in Idaho, there are the 2 quadriplexes of I-84/US 20/US 26/US 30, and at least 3 triplexes: I 84/US 30/ID 55, US 20/US 26/US 93, and I-15/US 30/US 91 (I'm old enough to remember when this was a quadriplex with US 191 as well).

I'd forgotten about that one. Then again, it's been 3 years since I was there. Colorado does odd things with their US Routes. They may follow the Interstates, but will follow their old alignments through town back to the Interstate.

InDOT also has a 12,000 mile cap on the state highway system. In order to extend the system, i.e. add a new freeway, they need to decommission another highway. They are not allowed by state law to have anymore than those miles alotted them. This is one reason why Indiana has so many multiplexes with so many different routes on them.

Back in the day (40's-50's) Downtown Cleveland at Public Square would have won the title in Ohio.
Southbound Ontario St @ Euclid Avenue, you would have had this multiplex:
SR-8
SR-14

SR-43* (truncated at SR-14 at the Broadway/Miles/E.93rd/Turney/Warner Road "interchange")
SR-87* (truncated at SR-8/US-422 at the Intersection of East 55th/Orange/Woodland Avenues)
US-422
(* - denotes routes since truncated)
Within Public Square, these 6 routes at one time or another connected with:
SR-2 (relocated to Shoreway)
SR-3* (truncated at US 42 at Pearl/Ridge Road intersection)
US-6
US-20

For all Maine's copious multiplexing, triplexing and quadruplexing, the Pine Tree state can only muster a single, uhh... help me out here; is it a Quintuplex or a Pentaplex? - and that's with one of the routes unsigned. According to the definition of ME121 in the route logs, it's carried along the entire US202/ME4/11/100 quadruplex in Auburn. Signage in the field has it ending as a useless duplex with ME11, as it meets US202 & pals.
The other eleven quadruplexes:

I've not attempted to make a list of all the triplexes, and fuhgeddabout the duplexes - such an effort would send me to the nearest mental bin.
Quintuplex (http://dictionary.reference.com/browse/quintuplex).
Here's the list I compiled for Minnesota (http://www.ajfroggie.com/roadpics/mn/multiplex/). The most the Gopher State can manage is a triplex, though we manage to have 8 of those, plus at least 2 known former ones. Disregard what I have on the list...the US 14/US 61/MN 16 is a former now.
What is the biggest concurrency from Georgia? I know there is a 7-route one near Folkston.

I've always found it weird to see US highways multiplexed onto an Interstate. You'll be hard pressed to find that here, with the exception of US 51/I-55 where it's too expensive to maintain both a four lane, twenty-five mile bridge, and a two lane bridge of the same length. Right after the Manchac Swamp Br, the highways split.
Can't think of any offhand, but does anyone know the most multiplexed routes on a multiplex in California?
New Mexico not allowing its state routes to run concurrent with any other route limits the potential number of concurrent routes. The only technical quadriplex is I-25/U.S. 85/U.S. 285 and U.S. 84 for a short distance east from Santa Fe, but New Mexico doesn't acknowledge U.S. 85's existence anywhere in the state and doesn't post the other two routes along their concurrency with I-25.
I can think of a few three-fers off the top of my head, I-10/U.S. 70/U.S. 180 from Deming to Las Cruces (the U.S. routes aren't posted), I-10, the unacknowledged U.S. 85, and unmarked U.S. 180 from Las Cruces to the Texas line; a short triple in Carlsbad with U.S. 62-180 and 285; and U.S. 60, 70 and 84 from Clovis east to the Texas line, the latter two of which are probably the only fully posted triplexes.
The only ones I know of in Louisiana are I-49/US 167/US 71 Byp in Alexandria on one end of Exit 84, and 49/71 Byp/La 28 on the other. You also have US 71/165/La 28 on surface streets. Back before 1955, when every US highway was paired with a state highway, the OK Allen bridge in Alexandria had US 71/US 165/US 167/La 1/La 5/La 99.

If you go waaaaay back (pre-1960) there was at least one Minnesota 4-route concurrency: University Avenue from Minneapolis to St. Paul carried U.S. 12-52 and MN 56-218.

Not counting underlying state routes, there is one quad-plex in FL. US 17/US 23/Alt US 90 (unsigned)/SR 228 share pavement for at least one block.
Signs on Laura Street notwithstanding, US 90 Alt has been rerouted out of downtown Jax for a while. There used to be a four before US 17 was rerouted: US 1/US 17/US 90/SR 228 on Main/Ocean.

Way back when on MTR, someone posted that such an example exists in Massachusetts, but i have been unable to find that post on Google Groups (someone must have had x-no-archive-yes activated) nor have I been able to find the example on the map. My fading memory seems to think it involved MA 2 as one of the routes, however.

MA sounds like a likely candidate, but my top pick would be PA, since so few of the roads in that state run true north-south, or east-west. Thanks for trying, will stay tuned.

I'll bet it had something to do with the MA 2-US 3-MA 16 intersection.
the Boise City, OK roundabout might have at one point had something that qualifies.
I don't think I would count any roundabout; even one which has been improved upon by a bypass that has elimitanted all the truck traffic. :-D

1934, when the major renumbering of highways took place. Actually, U.S. 52 and MN-218 were also established that same year. MN-56 was split in 1960, with the segment north of Minneapolis becoming MN-47 and 56 being terminated in downtown St. Paul, eliminating the University Avenue hyperplex. I think I have a map (MN official or otherwise) showing all four routes on that segment.
That link goes to Route 404, by the way (unless my work firewall is blocking it, and I don't see the usual net nanny message).

Technically, MA routes 1A and 3A run concurrently with their parent routes between their sections north and south of Boston. So the Cambridge example is officially MA 2-US 3-MA 3A-MA 16. This also makes the SE Expressway north of Neponset to Storrow Drive officially I-93-US 1-MA 1A-MA 3-MA 3A. I guess that this also means that I-95 between Exits 12 and 15 officially is I-95-US 1-MA 1A-MA 128.

One flaw with that thought/approach. Since the Big Dig entrance/exit ramp reconfigurations from a decade ago, someone heading southbound on MA 1A via the Sumner Tunnel can not directly get on the southbound O'Neill Tunnel (I-93/US 1 South). Conversely, there is no longer direct access from the northbound O'Neill Tunnel (I-93/US 1) to the Callahan Tunnel (MA 1A North) and the only
1A NORTH signs one sees while heading eastbound in the Ted Williams Tunnel (I-90) isn't until they're approaching the exit for Logan Airport (Exit 26).
The only
signed designated parent-alternate duoplexes in MA I'm aware of are US 1/MA 1A between Newburyport and Salisbury and MA 2/MA 2A between Lincoln and Acton.

I should've just copy/pasted. That photo is probably along Washington Ave. in downtown Minneapoiis, west of where 56 angled off. Mmmm. I think I'll have a Gluek after I get home.

Montana multiplexes (mainly based on concurrency):
I-90/US 93/MT 200 (through most of Missoula County)
I-90/US 212/US 310 (near Laurel, Montana west of Billings)
I-115/I-15/90 Business (the spur route into downtown Butte)
I-15/US 12/US 287 (Townsend and Capitol near Helena)
I-15 Business/US 89/MT 200/MT 3 (the I-315 overlap)
I-94/US 12 (formerly a multiplex with US 10/US 12/US 312, now MT 59)
US 87/MT 19/MT 200 (in Fergus County by Grass Range)
MT 2/US 212
MT 3/US 12 (in Golden Valley County)
MT 3/US 12/US 191 (in Wheatland County)
MT 3/MT 200/US 87/US 191 (in Fergus County near Moore, Montana)

Bump...Found another "Georgia Seven" in Hawkinsville the other day. It doesn't last long, perhaps just a half mile:

I was always partial to the 4-plex of US-421, SR-39, SR-25, SR-18 through downtown Delphi, IN. Beyond that, there are nearly 9 miles of 421/39/18 on either side.
Here are some that have 4:
US 4 / NH 9 / NH 107 / US 202
US 6 / US 7 / I-84 / US 202 (CT)
NY13 / NY 34 / NY 79 / NY 96
ME 4 / ME 11 / ME 100 / US 202
ME 11 / ME 100 / ME 135 / US 202
ME 11 / ME 17 / ME 100 / US 202
ME 17 / ME 100 / US 201 / US 202
ME 8 / ME 11 / ME 27 / ME 104
ME 3 / ME 9 / ME 32 / US 202
US 1A / US 6 / US 44 / I-195 (RI)
Maine loves multiplexes.
US 202 also loves multiplexes.
Yes, I know some of these have already been mentioned.
I know this is old but I just had to mention one here in Texas: in Beaumont there's a stretch that carries Interstate 10/US 90/US 69/US 96/US 287.
US 12/20/45 in Cook County/Chicagoland. We just call it Mannheim or LaGrange Rd.
I feel like we've had a thread on this since 2014...
Either way, Georgia has some huge ones. There is an 8-way concurrency on the southeastern leg of the Athens Perimeter - including GA 10 Loop, US 29, US 78, US 129, US 441, GA 8, GA 15, and unsigned GA 422.
