Last year, when I was clinching TX 19 on a trip back to college, I noticed something fairly strange. Going NB from the town of Crockett, TX 19 begins a pretty lengthy concurrency with US 287 that continues until the town of Palestine. The interesting thing is that on one side of downtown the routes diverge, but then they form another concurrency a couple miles later on the other side of town and continue concurrently for a couple miles after that. Here is a map of what I'm describing, with US 287 in blue and TX 19 in orange:

I think this instance of routes diverging and then remerging (especially so quickly) is pretty unique, but I'm curious if there are similar examples from around the nation, excluding examples of E/W or N/S splits on certain routes.
CA 1 and US 101 do this four times depending if you count unsigned concurrencies.
US 69 near Miriam, KS from I-35.
US-41 in Illinois between the Edens Spur and Russell Road (IL-WI border) is one that immediately comes to mind for me.
There's also I-90 and I-94 between Chicago and Madison if you want a longer one.
I can't think of any non-highway examples off the top of my head since Illinois is good about not having unnecessary concurrencies.
MN:
US 212/TH 5 from I-494 in Eden Prairie to just west of Mitchell Road, then duplex again through Norwood Young America (with TH 25)
US 61/TH 23 formerly duplexed from Hinckley to Sandstone, then had another duplex through Duluth
I-94 and US 10 formerly duplexed west of Fargo in addition to their currently existing one in St. Paul
I-75 and US-23 in MI and OH. Except when they re-merge in OH for a short distance, they are a wrong-way concurrency.
Most of the ones I can think of off the top of my head are pretty far apart between meetings.
-US 1 and 301 have concurrencies in Virginia and Florida
-US 60 and I-64 are concurrent across the Hampton Roads Bridge-Tunnel, and then again from west of Lexington into West Virginia
-US 33 and 250 in Richmond VA and Elkins WV
-former one is VA 5 and US 60 in Richmond and Williamsburg (the latter being wrong-way), but VA 5 now ends at 60 in Richmond instead updated that this is still a current one
US 301 with I-95 twice.
US 1 with I-95 several instances.
US 22 with I-78 enters and leaves in the Lehigh Valley Area.
Related thread: https://www.aaroads.com/forum/index.php?topic=2811. The linked thread is more inclusive because meeting twice is enough and doesn't require an overlap.
Not mentioned in that thread is MA 110 and MA 113 in Methuen, about 4 miles apart.
Oh there is US 9 in NJ now three times overlapped on the Parkway.
US 9 and NY 9N overlap twice with one a wrong way.
US 41 and US 11/64 in Chattanooga twice.
US 250; and US 340 meet twice in Waynesboro, VA as US 250 is the business route and US 340 is the Truck Bypass of Downtown.
WI-32 and WI-57 duplex south out of Green Bay, diverge north of Plymouth, then merge back (along with I-43) south of Port Washington.
US-45 and I-41/US-41 duplex on two separate instances, just northwest of Milwaukee and briefly in Fond du Lac.
NC:
US 15/501 is a long currency from Durham to Laurinburg. In Sanford, it is concurrent with US 1. It breaks to Carthage and returns to US 1 in Southern Pines, where it is concurrent through Aberdeen where is splits off south to Laurenburg.
US 29 and I-85 from the SC Border to Greensboro, NC.
Some more that have concurrencies on both meetings within a relative short distance
US 87 and US 287 in Amarillo TX
US 74 and US 76 in Wilmington NC
NC 32 and NC 37
NC 32 and NC 45 in Plymouth NC
NC 125 and NC 903
US 19 and US 74
US 221 and NC 194 (3 times)
Isn't it fairly common for a US Route to diverge from the Interstate for a while, then rejoin? Such as US-40 and I-70 in multiple locations.
US 6 and US 202 from Bear Mountain to Peekskill, NY; then again from Brewster, NY to Danbury, CT
I-94 originates from I-90 near Billings then they meet again in Wisconsin, and once again in Chicago.
US 6 and US 44 meet as a concurrency with I-84 to cross the Connecticut River on the Bulkeley Bridge, then meet again as US 6 leaves I-84 in Manchester for a concurrency to Bolton Notch, then meet yet again for a concurrency in Providence.

FTFY.
US 222 and PA 272 is a good example in PA. They have a short concurrency just north of the PA Line in Wakefield. Then PA 272 basically becomes the through route towards Buck while US 222 heads northeast to serve Quarryville. Both routes remerge in Willow Street (with PA 741 concurrent with US 222 at the remerge) to serve Lancaster before US 222 heads east with US 30 to its freeway to Reading while PA 272 follows the pre-freeway routing of US 222 to its northern terminus at the US 222/PA 568 interchange north of Dover and the PA Turnpike.
US 9W and NY 32 concur at least twice. If not they cross paths several times.
Then US 4 and NY 32 meet twice. Both in Mechanicsville and Schuylerville and once more, I think, near Hudson Falls.
Oh wow, this one hasn't been mentioned yet: US 62 & US 82 at Lubbock, TX

I thought it had been officially truncated a few years ago when the Main/Dock roundabout was built, but I seem to have misremembered. It's certainly not posted westbound past the roundabout, and there are no postings anywhere that I can see at Main and Williamsburg. There are a couple trailblazers eastbound on Main, one at 25th and one at the curve just past Poe's Pub, but they look old enough to be pre-2003.

The CTB has stopped regularly documenting reroutes and truncations that don't result in fewer primary route-miles (as would the case be with VA 5 cut back on its US 60 concurrency).
The WB posting by Poe's Pub was removed in 2014-15 and to be fair so was the US 60 posting.
All kinds of examples could be cited in Kentucky. Probably the most obvious example is US 60 and 62. They enter the state from Illinois (concurrent with US 51) and diverge in Wickliffe. They become concurrent again in Paducah before diverging east of town. They follow separate paths to Versailles, where there is a short wrong-way concurrency of US 60 east and US 62 west (and vice versa) before splitting for good.
US 19 and WV 16 do a pretty involved dance between North Beckley and Fayetteville.
I-90 and US 14 overlap 3 separate times in Wyoming and western South Dakota, then reunite in Minnesota
And of course there's the case of I-84 and US 30, which diverge and merge several times in Oregon and Idaho due to the latter's secondary job of serving bypassed downtowns.
I-5 and CA 99, at Wheeler Ridge, Sacramento and Red Bluff.
US-64 and US-74 are concurrent when entering North Carolina from Tennessee. They split at Murphy and the merge back together at Bat Cave. Murphy and Bat Cave are only 130 miles apart driving distance, but in the middle the two routes are about 30 apart as the crow flies.
US-64 and US-70 used to merge and diverge in North Carolina, but now they just criss-cross each other a bunch of times. And they also touch each other and go back their separate ways in the west side of Statesville.
That Texas Route 256 looks like it's a loop route.

The 2021 traffic data log (https://www.virginiadot.org/info/resources/Traffic_2021/AADT_127_Richmond_2021.xlsx) does still say 5 runs with 60 to 25th, so my initial thought was wrong and it is still eligible for this thread.
US 12 and 20
In Iowa, I-380 is concurrent with US 218 for its first 16 miles and last 1 1/2 miles, with US 218 splitting off from I-380 at US 30 and rejoining I-380 at US 20.
Another example is US 218 and IA 27, with them being concurrent from Donnellson to Cedar Rapids and again from Cedar Falls to Floyd.
US 6 is on and off of I-80 across Iowa due to many sections of US 6 being decommissioned.
Looks like nobody has mentioned US 6 and US 50 yet. Those are concurrent from Ely NV to Delta UT, where they split only to reunite at Green River and continue overlapped to Grand Junction.
I-15 and US 89 overlap three times: once for a relatively short distance south of Salt Lake City, another short overlap north of Salt Lake City, and then again way up in Montana north of Great Falls.
Those are the only ones involving Utah to my knowledge. It is way more common in Colorado especially with interstates. US 6 jumps off I-70 and returns back to it several times. I think US 24 does that once as well in eastern Colorado. US 85 and US 87 do the same with I-25 (three times for 85, twice for 87).

I-39 and US 51
I-80 and US 6
NH/ME 9 and US 202. Concurrent from Hillsborough to Concord, NH. Meet again at the east end of I-393 in Pembroke and concurrent again until Barrington. Then they meet a third time in Augusta, ME and are concurrent to Hampden. And they even meet a 4th time along I-395 in Bangor.
I-84 and US 6 have 3 different concurrencies in CT alone: through Danbury, Newtown-Southbury, and Farmington-Manchester.
US 20 and NY 5: first for a little bit west of Buffalo, then again for far longer, from Avon to Auburn.
It's probably either ON 418 or NY 418. In any case, ON 418 is the closest in the same country while NY 418 is the closest internationally.
I-95/US 17 concurrent for 11 miles north of Ridgeland, SC, then they are concurrent for 7 miles around Fredericksburg, VA.
Edit: Can add a small I-95/US 17 concurrency in Jacksonville, FL with this.
KY 9/KY 10 from Germantown to Maysville and again from Ribolt to the Grayson/Greenup AA Highway split east of Vanceburg.
US 60 on I-64 twice in VA. Then again in Charleston, WV making 3 times for those two.

If by "non-highway" you mean "non-Interstate", then I agree. I can't come up with one either.

The other one isn't in Illinois; it's in Nebraska and Colorado.
US 60 & US 62 converge and diverge a few times between Charleston, MO and Paducah, KY
OH 2 is concurrent with I-90 from near Elyria to Westlake then again from near downtown Cleveland to Euclid.
OH 2 is also concurrent with US 6 near Bryan, again briefly in Huron, then again from Westlake to Cleveland.
US 6 and US 20 are concurrent in Fremont, OH, then again in Lakewood to downtown Cleveland, then again from East Cleveland to Euclid.
Here in Colorado, there's of course the US 40 multiplex with I-70 east and west of Denver, and multiple US 6 multiplexes and divergences with I-70 from Denver all the way to UT.

The arcgis map still shows VA 5 ending at 25th. If you scroll way in so that the info box won't cover Main at 25th and click on VA 5 at the new traffic circle, the info box has several designations. When you get to VA 5, you will notice that the segment still goes to 25th.
SH-155 and US-271 do this first in Gilmer then from East Texas center east of Tyler into Tyler.
In Texas and LA US-90 and I-10 do it a lot.
Likewise with US-67 and I-30.
These interstates that loosely follow the track of a US-Highway are numerous and they diverge and merge many times.

There are actually two 6/34 overlaps west of Illinois: one from Culbertson to Hastings in Nebraska, and one from Wiggins to Fort Morgan in Colorado (which is also concurrent with I-76).
I know that I-10 and US-90 meet up in San Antonio then separate in Seguin, and then remerge in Katy, and re-split in Houston and rejoined in Beaumont, only to split just past the Sabine River just before Vinton, Louisiana.
I believe that US-281 and I-37 join forces near Three Rivers -- then for a couple of years, split up just south of Whitsett and rejoined just north of Campbellton (the original US-281 passed through both of those towns while I-37 was routed around both towns) until that section of the original US-281 was redesignated as US-281 Alternate -- and re-split near Pleasanton and rejoined at the I-37/I-410 stack interchange.

Your post is on point. I don't know, if it's the winner, but those concurrencies are honest. My comment, which is off OP's question entirely, is that CASR-33 seems to have honest concurrencies with a large number of other highways.
I'm not sure of the signing on the ground, but the maps look like CASR-14 and US-395 do some of what the OP had in mind.

I-75 and US-23 in MI and OH. Except when they re-merge in OH for a short distance, they are a wrong-way concurrency.
They meet again in Macon, Georgia.
US 41 and M-26 merge in Houghton to cross the Portage Lake Lift Bridge, diverging on the other side in Hancock. They re-merge at Calumet until they diverge again at Phoenix. They meet one last time in Copper Harbor where M-26 terminates a couple miles from US 41's terminus.

I-5 and CA 99, at Wheeler Ridge, Sacramento and Red Bluff.
I-405 and I-5 from the San Fernando Valley and meet again at the El Toro Y in Irvine.
US-101 and CA-1 meet and Split in various places one at Leggett, another one at the Golden Gate Bridge and another one in a section between Ventura and Santa Barbara county.
Here are some of the California ones.
However at one point Business 80 Sacramento used to meet in two points one in West Sacramento and another in North Highlands but CalTrans removed the Business 80 signs between West Sacramento to Midtown Sacramento where the CA-99/CA-51 interchange and relabeled them as simply US-50 in 2016.
US-19 and WV-16 have a long history of being intertwined. Then in 1947, US-19 was relocated and separated from WV-16 completely. After completion of Corridor L, US-19 was once again back alongside its partner WV-16 from Beckley northward to Oak Hill: WV-16 joins US-19 on the north side of Beckley; keeps going straight on as US-19 joins Corridor L. Then WV-16 rejoins US-19 on Corridor L just north of Scarbro, but the overlap is roughly 1/4 mile before exiting the Oak Hill Expressway. The other one doesn't count, but WV-16 runs alongside US-19 on Corridor L north of Oak Hill for about 3/4 mile between the Lochgelly Road exit and where South Court Street used to leave Corridor L going into Fayetteville. WV-16 may have been concurrent with US-19 on that short stretch before the South Court Street intersection was removed.
Fun fact: WV-16 was not originally part of the multi-state MSR-16 connecting North Carolina and Virginia. The original routing of WV-12 was absorbed into WV-16 to create the multi-state route that connected through West Virginia all the way cross into Ohio. The State Road Commission tried on several occasions to convince AASHO to pull WV-16 into the U.S. highway numbering system.
