In Asheville, NC the expressway heading out of town to the north carries US 19, US 23, US 25, US 70. Its is also technically Future I-26, but everyone just calls the road I-26.
I know we've done this before, and I'm sure someone else will link to it before too long.
There is a segment of I-65 that carries 7 other highways. Will be 8 when I-69 from Bloomington to Indy is finished.
Phoenix used to have concurrency of US 60, 70, 80, 89, along with AZ 93.
(https://www.arizonaroads.com/maps/1961-5.jpg)
One big concurrency I used to encounter was US 17/92/441 near downtown Orlando on Orange Blossom Trail.
Ran into US 84/431, AL 210, AL 52 Truck in Dothan last year.

In Utah, there is a quadraplex of I-70/US 6/US 50/US 191, but none of the US routes are signed.
All the routes on I-465 around Indianapolis. 'Nuff said.
Unless there's been some major US re-routes in the past few years, the towns of Folkston and Hawkinsville, Georgia have 7-way concurrencies.

Fort Wayne, Indiana once had an 8-way overlap. Can't find the photo, but it was from the mid-1960s.

Also a bit nutty...but the overlaps join and leave different exits on I-465 (at least, for now).

But that stretch of I-465 between exits 46 and 47 technically carries, like, eight routes IIRC.
Kentucky has US 23, US 119, US 460, KY 80 and KY 1426 in Pikeville, which for years I thought was the largest number of concurrencies in the state.
But I believe now, after having driven through there last year, that it is equalled by US 41, US 68, KY 80, KY 107 and KY 109 in Hopkinsville.
When I saw this thread, the first thing that came to my mind was the Athens Perimeter (limited-access) in Athens, Georgia.
Sure enough, I found this here (https://en.m.wikipedia.org/wiki/Georgia_State_Route_10_Loop_(Athens)) on Wikipedia:
https://en.m.wikipedia.org/wiki/Georgia_State_Route_10_Loop_(Athens)
Quote
Between exits 4 and 8, there is an eight-highway concurrency, consisting of US 29/US 78/US 129/US 441/SR 8/SR 10 Loop/SR 15/SR 422 (counting the unsigned SR 422). This concurrency comes second in the American record of most highways in a single concurrency. The record holder is Interstate 74 (I-74), Interstate 69 (I-69), I-465, US 31, US 36, US 40, US 52, Indiana State Road 37 (SR 37), and SR 67 in the Indianapolis, Indiana metropolitan area.
The Athens Perimeter comes in second place, and first place is the I-465 Beltway in Indianapolis.

The most routes I can find on one road in Michigan is three:
BL I-94/BUS US-131/M-43 in Kalamazoo
US-31/M-37/M-72 in Traverse City
US-131/M-66/M-72 in Kalkaska
If we're going by state, NJ s pretty sparing with its concurrencies, I-95/US 1/US 9/US 46 approaching the George Washington Bridge is the most. I don't think there is anything else greater than 2 routes unless it involves county routes. Even then I don't think so.
One variation that I've found:
Just outside Halifax NC, a road briefly carries four three-digit routes (US 301, NC 125 / 561 / 903).
Wonder if there is a quadraplex in MA. I can think of triplexes, like US 5/MA 10/MA 116 or MA 2/US 3/MA 16. Probably is a four route one somewhere out east.
Among routes and systems plotted in TM, all of the 8's and the only 9 are on I-465 around Indianapolis. The 9-route segment carries
I-465,I-69FutInd,US31,US36,US40,US52,IN37,IN67,US421
This assumes that "Future I-69" counts for purposes of this discussion.
Here are TM's 7-way concurrencies that aren't also on I-465.

That's a good question. Outside of
silent concurrencies like 1/1A or 3/3A concurrent with other routes, I don't believe there are any in New England.
I know MA has some expressway triplexes such as I-93/US 1/MA 3 (the Southeast Expressway from Boston to Braintree), I-95/US 1/MA 128 (from Canton to Dedham) & I-95/US 3/MA 128 (Burlington).
Near Newtown (Bucks County), PA; a stretch of the Newtown Bypass has a triplex, PA 332/413/532.

1A/6/44/195 (RI)
4/9/107/202 (NH)
And
many in Maine.
In CA (pre-'64, of course) the record was 5 designations on one stretch of freeway: I-15, US 66, US 91, US 395, and CA 18 on the N-S freeway through central San Bernardino between the 5th Street entrance ramp (where US 66 "got on") to the East Highland Ave. exit, where CA 18 departed; a stretch of a little over a mile. It got down to 4 when CA 18 was truncated at I-15 in 1961. Tied for 2nd would have been the Pasadena Freeway (nee' Arroyo Seco Parkway) between the Four-Level and the Ave. 26/North Figureroa left exit in the Glassell Park section of L.A.; it carried US 6, US 66, US 99, and CA 11; all but US 66 departed at the Ave. 26 exit. And, between 1959 and 1964 completed freeway sections of I-10 between Beaumont and Indio also carried US 60, US 70, and US 99. Those "sign salads" were part of the rationale for the radical (and some may say horribly randomized) 1964 renumbering effort -- with the "one road/one number" sentiment prevailing within the Division of Highways at the time.
Here is the list of I-465 around Indianapolis. I am going to use the SE Corner just north of the I-74 exit and north of the US 52 exit, since I think that has the most roads piggybacked.
I-465 (future I-69)
US 31, US 36, US 40, US 421, US 52
Indiana 67, Indiana 37
I don't think other than the interstates, no other roads are regularly posted on the loop. You just have to follow the signs from the road that you were leaving, and hope that you catch the sign for the road that you wish to continue on the opposite side of the city.

I forgot about that one but while going through GSV, I noticed that there's no signage along I-195 westbound indicating that Exit 2 (for US 44 West) is also for US/RI 1A southbound as well. While that concurrency is indeed there; it's very inconsistently signed.

only the interstates are signed on 465, all the us and state routes just have signs saying " *insert highway here* follow i-465 to *insert exit number here* i think the only exception is us 36/sr 67 on the east side, they forgot to put the signs back when they widened the road back in the day. and the one for fort wayne was i believe: us 24/30/33 sr37/14/1/3 maybe? i had the picture you're referring to i found it somewhere, I've since lost it.

In 1953 (pre-interstate), there were multiple concurrencies of four or more routes:

BUS US-16/BUS M-21/M-37/BUS M-50 along Fulton St from Eastern to Cascade (Grand Rapids)
US-31/US-33/US-112/M-60 along Main St from Front to 11th (Niles)
I'll mention Wisconsin only to note that adding I-41 to the mix doubled our count of quadruple concurrencies.

US-40, US-50, CASR-160, CASR-16, US-99, CASR-70 were all carried by the W-X freeway in Sacramento at one point. I am not sure that all of the US-40 signs had disappeared when the I-80 signs showed up.
By the time the W-X freeway was completed in 1969, CA 70 ended (SB) at the corner of 3rd Street and Capitol Mall, the latter of which still carried US 40 and US 99W shields west of that street. Wanting to get through traffic away from the Capitol, US 40 and CA 16 were rerouted down the 3rd Street/5th Street N-S (respectively) couplet; then turning east on Q Street, which was a couplet with P Street (WB). US 40 then turned north on 16th Street as part of
its couplet with the SB 15th Street; heading north and east out of town via the North Sacramento Freeway. That alignment was created in 1965 and lasted until the W-X freeway was done and signed as I-80; at that time US 40 was superfluous (having been decommissioned 5 years earlier) and signage was removed; the single remaining old expressway portion of the SF-Sacramento route south of Davis was signed as "Temporary I-80" until the 1973 opening of the new I-80 facility, which included the interchange with CA 113 toward Woodland;
that facility had lost its former US 99W signage the prior year when I-5 was completed north of Woodland toward Red Bluff. But from 1963 to 1970 the freeway section from Davis to West Sacramento was "triple-signed" as I-80, US 40, and US 99W, regardless of the fact that the US routes were officially decommissioned back in 1964. Also, about that time Temporary I-5 signs were applied to the original I-80 from the I-5 interchange area in Sacramento west over the Yolo Bypass to CA 113 and on CA 113 north to the I-5 crossing north of downtown Woodland, pending the opening of the I-5 version of the Yolo Bypass closely paralleling old CA 16; that viaduct was the final segment of I-5 to open between Sacramento and I-505. I recall seeing the "TEMPORARY"-bannered I-5 shields sharing the I-80 reassurance masts circa 1969-70; those actually replaced the US 99W signage. As far as US 40 shields west of Sacramento, most were gone by 1973 or so -- although a few stragglers remained around the segment between Vallejo and Fairfield until it was reconstructed in the mid-70's.

For West Virginia, there are three 4-route multiplexes. All are in Randolph County:

No. That stretch (I-465 between exits 46 and 47, as I mentioned above) is just north of the eastern I-74 interchange. I-74 continues south and west from there.

Tennessee has many large multiplexes, due to their tendency to assign hidden state routes to each US route, as is common practice in southern states. However, they're very inconsistent about signing them. US routes may or may not be signed when they concur with an interstate, but don't expect to see a state route in a concurrency with anything other than another state route get signed, so most people driving on these don't realize how ridiculous the multiplexes actually are. Including the hidden routes might be a little bit cheating, as it means that any concurrency with a US route involved will be at the very least a triplex, but I'm still including them.
Nashville has quite a few ridiculous multiplexes. The James Robertson Parkway in Nashville carries US-31/41/431/unsigned SR-6/11. Only the first three are signed, however. The state routes are Tennessee's famous hidden designators. Up ahead US-31 will split in two, but 31W continues on the multiplex while 31E goes its separate ways. Interestingly, it's directly preceded by a brief hexaplex on 8th Avenue consisting of US-31/41/70S/unsigned SR-1/6/11, which then meets Broadway, which is yet another five-way consisting of US-70/70N (yes, a bannered route is concurring with its parent...only in Tennessee I guess)/431/unsigned SR-1/24. 70N and S have their west end at this intersection, but 431 will join 31 and 41 onto the Parkway. 70 and 24 continue east on Broadway.
Asheville Highway east of Knoxville briefly carries US-11E/25W/70/unsigned SR-9/signed SR-168. 25W and 9 are themselves coming off of a short triplex with I-40, following a longer triplex with I-640 north of town. 11 and 70 have a long triplex from the western outskirts of Knoxville all the way to downtown with unsigned SR-1 (Kingston Pike/Cumberland Ave/Magnolia Ave), which followed US-11W at the 11W/E split. 168 originates at US-129 north of Maryville and is signed for most of its solo route, but only the US routes are signed on this concurrency.
Northeast of Chattanooga at Cleveland, Tennessee, US-74 (which surprisingly ISN'T carrying a hidden state route with it) hops onto I-75 for a duplex. In Ooltewah they are joined by US-11/64/unsigned SR-2, which began a triplex in downtown Cleveland. Between exits 11 and 7B, I-75 carries five routes, but you would never know as none of the routes save for the interstate are signed.
The most famous multiplex, however, is the one of I-55/US-61/64/70/79 on the Memphis-Arkansas Bridge crossing the Mississippi. As they enter Memphis, the US routes will leave the interstate to become Crump Boulevard, where they continue as a quintuplex for a short time with unsigned SR-1. The bridge concurrency is not signed in the eastbound direction but is in the westbound, making it the largest concurrency that's signed in Tennessee.

That's a good question. Outside of silent concurrencies like 1/1A or 3/3A concurrent with other routes, I don't believe there are any in New England.
1A/6/44/195 (RI)
4/9/107/202 (NH)
And many in Maine.
I-84/US 6/US 7/US 202 in Danbury, CT says hi.
Also I-95/US 1/US 9/US 46 for 1.16 mi. from the 1/9/46 exit to the center of the GWB.
If you do count silent concurrencies, you have I-93/US 1 /MA 3/silent MA 1A/silent MA 3A from the Braintree split to the Sumner/Callahan tunnels. You also have I-95/US 1/MA 128/silent MA 1A between Dedham and Canton.

The most famous multiplex, however, is the one of I-55/US-61/64/70/79 on the Memphis-Arkansas Bridge crossing the Mississippi. As they enter Memphis, the US routes will leave the interstate to become Crump Boulevard, where they continue as a quintuplex for a short time with unsigned SR-1. The bridge concurrency is not signed in the eastbound direction but is in the westbound, making it the largest concurrency that's signed in Tennessee.

I've seen old maps that also show US 63 on that bridge and entering Tennessee.

True, but NJ isn't one of the New England states. Rothman, "1" and I were strictly talking about New England examples.

Actually, MA 3A south exits off its parent at Neponset Circle (Exit 12) near Milton. From there south to Braintree, it's simply I-93/US 1/MA 3/silent 1A along the Southeast Expressway.

That easily could be true. I don't know where it would have been routed after going over the bridge, though. Did it stay in West TN or dip right back into AR?

sorry for bumping a three year old post but I found this and wanted to offer as an example:
In Beaumont, Texas: Interstate 10/US 90/US 69/US 96?US 287. Its a very short concurrency and only appears on one sign, but even once US 90 leaves at the next exit, the road still continues as Interstate 10/US69/US 96/US 287.

In CA (pre-'64, of course) the record was 5 designations on one stretch of freeway: I-15, US 66, US 91, US 395, and CA 18 on the N-S freeway through central San Bernardino between the 5th Street entrance ramp (where US 66 "got on") to the East Highland Ave. exit, where CA 18 departed; a stretch of a little over a mile. It got down to 4 when CA 18 was truncated at I-15 in 1961. Tied for 2nd would have been the Pasadena Freeway (nee' Arroyo Seco Parkway) between the Four-Level and the Ave. 26/North Figureroa left exit in the Glassell Park section of L.A.; it carried US 6, US 66, US 99, and CA 11; all but US 66 departed at the Ave. 26 exit. And, between 1959 and 1964 completed freeway sections of I-10 between Beaumont and Indio also carried US 60, US 70, and US 99. Those "sign salads" were part of the rationale for the radical (and some may say horribly randomized) 1964 renumbering effort -- with the "one road/one number" sentiment prevailing within the Division of Highways at the time.
US-40, US-50, CASR-160, CASR-16, US-99, CASR-70 were all carried by the W-X freeway in Sacramento at one point. I am not sure that all of the US-40 signs had disappeared when the I-80 signs showed up.
I knew in places like Vallejo US-40, I-80 and I-5W were co-signed at the same time at one point until the renumbering removed US-40 and I-5W from what is now the Solano County section of I-80https://www.aaroads.com/shields/show.php?image=CA19580801 (https://www.aaroads.com/shields/show.php?image=CA19580801)

Maryland has one four-route concurrency of I-595, US 50, US 301 and MD 2 in Annapolis. There is also a three-route concurrency of MD 16/313/404 in Denton, on the Eastern Shore.

Among routes and systems plotted in TM, all of the 8's and the only 9 are on I-465 around Indianapolis. The 9-route segment carries
I-465,I-69FutInd,US31,US36,US40,US52,IN37,IN67,US421
This assumes that "Future I-69" counts for purposes of this discussion.
Isn't I-74 on this segment, somewhere, as well? I guess that depends on which route I-69 takes, being North and West or South and East sides
No. That stretch (I-465 between exits 46 and 47, as I mentioned above) is just north of the eastern I-74 interchange. I-74 continues south and west from there.
It never will actually be 9 though. Once I-69 is signed, IN-37 will be decommissioned between Bloomington and Fishers.
For a variation, how about different routes along different segments of the same road (not multiplexed)?
In Michigan, Gratiot Avenue between Detroit and Port Huron carries parts of M-3, M-19, and BL I-94 on three separate segments.

I-465 would be pretty much every route in the concurrency mentioned above, in addition to I-74. That'll be 9 routes.
Broad St in Columbus: US 40, US 62, OH 3, OH 16
3rd St/4th St pair in Columbus: US 23, US 33, US 62, OH 3
Detroit Ave in Cleveland: US 6, US 6 Alt, US 20, US 42, OH 3, OH 254

Tennessee has many large multiplexes, due to their tendency to assign hidden state routes to each US route, as is common practice in southern states. However, they're very inconsistent about signing them. US routes may or may not be signed when they concur with an interstate, but don't expect to see a state route in a concurrency with anything other than another state route get signed, so most people driving on these don't realize how ridiculous the multiplexes actually are. Including the hidden routes might be a little bit cheating, as it means that any concurrency with a US route involved will be at the very least a triplex, but I'm still including them.
Nashville has quite a few ridiculous multiplexes. The James Robertson Parkway in Nashville carries US-31/41/431/unsigned SR-6/11. Only the first three are signed, however. The state routes are Tennessee's famous hidden designators. Up ahead US-31 will split in two, but 31W continues on the multiplex while 31E goes its separate ways. Interestingly, it's directly preceded by a brief hexaplex on 8th Avenue consisting of US-31/41/70S/unsigned SR-1/6/11, which then meets Broadway, which is yet another five-way consisting of US-70/70N (yes, a bannered route is concurring with its parent...only in Tennessee I guess)/431/unsigned SR-1/24. 70N and S have their west end at this intersection, but 431 will join 31 and 41 onto the Parkway. 70 and 24 continue east on Broadway.
Asheville Highway east of Knoxville briefly carries US-11E/25W/70/unsigned SR-9/signed SR-168. 25W and 9 are themselves coming off of a short triplex with I-40, following a longer triplex with I-640 north of town. 11 and 70 have a long triplex from the western outskirts of Knoxville all the way to downtown with unsigned SR-1 (Kingston Pike/Cumberland Ave/Magnolia Ave), which followed US-11W at the 11W/E split. 168 originates at US-129 north of Maryville and is signed for most of its solo route, but only the US routes are signed on this concurrency.
Northeast of Chattanooga at Cleveland, Tennessee, US-74 (which surprisingly ISN'T carrying a hidden state route with it) hops onto I-75 for a duplex. In Ooltewah they are joined by US-11/64/unsigned SR-2, which began a triplex in downtown Cleveland. Between exits 11 and 7B, I-75 carries five routes, but you would never know as none of the routes save for the interstate are signed.
The most famous multiplex, however, is the one of I-55/US-61/64/70/79 on the Memphis-Arkansas Bridge crossing the Mississippi. As they enter Memphis, the US routes will leave the interstate to become Crump Boulevard, where they continue as a quintuplex for a short time with unsigned SR-1. The bridge concurrency is not signed in the eastbound direction but is in the westbound, making it the largest concurrency that's signed in Tennessee.

The concurrancy you speak of on 8th Ave actually is US 31/41/41A/70S. Yes US 41 and US 41A run concurrent.
I-20, I-55, US 49, US 51 (unsigned), and MS 18 (unsigned) briefly share a concurrency. Further east, I-20, I-59, US 80, US 11, and MS 19.
Illinois currently has a 4-way concurrency in E St Louis, that used to be a 5-way
Currently: I-55/I-64/US 40/IL 3. Used to also have I-70, until the Stan Span opened and I-70 was routed off the PSB and its approaches
