Pretty simple. Two highways that run concurrent/multiplexed/whatever you call it but on separate lanes. Kinda like I-45 and I-10 (https://www.google.com/maps/@29.7733037,-95.3680305,1294m/data=!3m1!1e3?authuser=1),

I-94 and the I-35s in Minneapolis and St. Paul?
US 9 and the Garden State Parkway in Woodbridge, NJ.
I-85 and I-286 in southwest Fulton County, Georgia.
If they're on separate lanes, they might not be truly "concurrent". For example, Interstate H-1 and HI 92 have the same centerline between H-1 exits 15 and 18, but H-1 is on a long viaduct above the ground-level HI 92, and the two highways are treated by HDOT as separate, non-concurrent/multiplexed routes.
Similarly I-65/US 31 north of Louisville, Autoroute A-440/Quebec 335 north of Montreal, and part of Autoroutes 10 and 55 (share lanes and roadway) and Quebec 112 (separate sets of non-concurrent lanes) between Magog and Sherbrooke. In those cases, the lesser highway runs along the freeway on frontage roads.
Is NY 27 concurrent with the Belt Parkway on Long Island? Or is it routed on the frontage roads. I imagine the latter, but that is cause trucks are banned on NY Parkways. However, state routes do not need a truck alternate and NYSDOT could actually have a bannered one along the service roads.
NY 27 uses the frontage roads. Regarding truck prohibitions, if I remember right, not being on a designated truck facility is the reason why NYCDOT doesn't sign the portion of NY 24 that runs through the city.

So it counts as far as the OP is concerned if I interpret it as two routes in the same ROW but separate lanes. I think that is what Oscar was pointing out that the title is sort of not correct to its true meaning.
Yeah, sorry. I'm not really sure what to call it. As long as they're two or more highways that run along the same path (but on different lanes), then it's fine.
I-73 / I-85 near Greensboro, NC - I-85 runs on the inside lanes and I-73 runs on the outside lanes.
I-69E / SH-44 in Robstown, TX - I-69E runs on the inside mainline, SH-44 runs on the frontage roads.
I suppose that I-91 and CT 15 does sort of in two places where I-91 is in the median of the CT 15 freeways.
US 92 and I-4 near Tampa is another as for almost a mile both routes run together but separate.
US 1 & 90 and I-95 do that now in Jacksonville and the US routes use a c/d roadway of the interstate.

I-83 and I-695 fits this description. While I-695 uses the inner mainline, I-83 goes on the outer lanes, and both ends are exit only.
Are you talking about separate roadways? Lanes are the spaces between painted lines on the same bit of pavement. Roadways are the traveled portions of a highway between shoulders/berms/barriers/etc.
Would the Thruway and I-790 in Utica count?
I think NY 7 and I-87 near Albany count as half, since northbound shares a roadway while southbound is grade-separated, as seen here (https://www.google.com/maps/@42.7579286,-73.76506,3a,75y,235.95h,72.73t/data=!3m7!1e1!3m5!1sPFkqG2550MkaSWWRc0B-qQ!2e0!6s%2F%2Fgeo3.ggpht.com%2Fcbk%3Fpanoid%3DPFkqG2550MkaSWWRc0B-qQ%26output%3Dthumbnail%26cb_client%3Dmaps_sv.tactile.gps%26thumb%3D2%26w%3D203%26h%3D100%26yaw%3D115.04404%26pitch%3D0%26thumbfov%3D100!7i13312!8i6656).
The recent reconstruction of the I-80/29 intersection in Council Bluffs, IA created a "dual divided freeway" where the two routes had previously run on the same roadway, although the inner lanes are signed as I-80 Express and the outer lanes are signed as I-29/I-80 Local, so I guess it's a partial concurrency :hmmm: (https://www.aaroads.com/forum/proxy.php?request=http%3A%2F%2Fcouncilbluffsinterstate.iowadot.gov%2Ffiles%2F5215%2F6571%2F7001%2FI-80EB_I-29SB_DDF-DecisionPoints_20190812a.jpg&hash=4f59adce7212d2f867043423d2ef3830b0bf9bfe)

Also want to add I-465 at Shadeland Avenue (also not a numbered route) on the East side of Indy.
The Dulles Toll Road (VA 267) is officially a separate designation from the free Dulles Access Road (VA 90004) which runs inside its median from Dulles to VA-123.
I-66 runs within the median of US-29 for a short distance in Arlington.
I-84 and CT 72 do for about a half mile in Plainville. The left 2 lanes EB and the right 2 lanes WB are CT 72 lanes. It turns into a slalom course with all the weaves between lanes to switch roadways.

Should google maps be the arbiter of this question? I'd want to do some digging into TIGER files to really know. I'll admit I've taken some shortcuts myself when it comes to placing highway shields on GIS maps.
I guess I-15 and US 89 north of Salt Lake City (https://www.google.com/maps/@40.8258368,-111.9166101,15z) might qualify, but I've never thought of that segment as a concurrency in the same way as something like 85/285.

Then it's not a concurrency. Since that requires that they be on the same roadway.
https://en.wikipedia.org/wiki/Concurrency_(road)
QuoteA concurrency in a road network is an instance of one physical roadway bearing two or more different route numbers.
These instead are braided or inner/outer highways. But the route numbers do not share a roadway so they are not a concurrency.
This thread subject is an oxymoron. It's asking for something which can't occur.
My interpretation is that it is effectively asking for two highways that do not form a concurrency but do share the same ROW.

I'd say there's a need since there seems to be some confusion from the incongruous subject. Which could be why there's one example given in the thread that's incorrect (I-695/I-83) and the confusion regarding I-76/NJ42 and I-295. Which that one could be unique in that it wasn't on the list in the past (due to the concurrency), is on the list now, but will not be on list in the future (with no concurrency).

How long ago is "the past"? All of the GSV images of that location I have been able to find show a barrier.
Replace the concrete barrier with a wide paved neutral space–or even just a fat white line–and you would indeed have a true concurrency running on separate lanes. I find it hard to believe we can't come up with an example somewhere in the world.

What advantage would there be to designate a road as like, "left lanes are route A, right lanes are route B" instead of just "all lanes are route a/b" ?

Or even just regular striped lanes situated in such a way that through traffic for each road is separate. The northbound I-87/NY 7 overlap does this; two lanes for NY 7 enter at exit 6, stay as auxiliary lanes for a short distance, and then leave at exit 7. At no point does thru traffic for either road have to interact with thru traffic from the other; only traffic switching routes has to merge. The two groups of lane are separated by the thick dotted line normally used for denoting exit/entrance lanes throughout.
Similar story for I-90/I-87, though there is an intermediate exit ramp eastbound/northbound, and the toll barrier complicates things here.

That's a decent example. I was imagining a big, thick, solid white line; but the dotted line is similar.

Well, as shown above, traffic might already be channelized in that way. Why build an expensive barrier, if some pavement stripes will basically do the same thing. In the example above, of course, interchanging between "halves" of the highway are possible–but the theoretical separation does exist. The three left lanes start out as I-87 and then, at the next exit, continue on as I-87. The two right lanes start out as NY-7 and then, at the next exit, continue on as NY-7.

Somewhere around Dec., 2013.
Now, there's a little trickery involved here. This GSV should show it fairly clearly: https://goo.gl/maps/mH1Zo3rAwPUJu2bMA . There's always been a barrier in the general area. However, previously, it separated the I-76 Express Lanes from the I-76 Local Lanes and I-295. Eventually they did away with the Express/Local lane division, and combined those lanes, but then separated I-295's carriageway from I-76. So prior to December, 2013, you'll see the old setup, and after that date you'll see the current setup.

The I-83/I-695 scenario mentioned further up the thread (as quoted below) seems very similar to the example vdeane and kphoger are discussing. The short skip lines denoting an exit extend the full distance between the concurrency's endpoints (roughly a mile).

Interstates 88 and 355 near Downers Grove, IL share the same ROW and are intertwined (but separate) for close to a mile before going their separate ways.

Cordoned off shoulder; the lane that extends from the onramp from Paloma Road (the segment of 84 going west to the town of Sunol) north to the offramp from 680 to the Vallecitos Road segment of 84 is one extended auxiliary lane on its own.

Are the lower and upper levels on I-10 in San Antonio (https://www.google.com/maps/@29.4571543,-98.5156892,3a,75y,168.75h,88.07t/data=!3m6!1e1!3m4!1sDCyVC_x-NDHPSLIxEG3sMg!2e0!7i16384!8i8192) considered the same or separate highways?
It's all I-10–similar to express/local setups elsewhere.

I would say a better example would be I-35 and I-10/US 87, since I-35 takes the lower level and I-10 takes the upper level.

No one's mentioned AP-7/E-15 and B-30 outside of Barcelona?

I've always thought that setup was screwy. You can take
either upper or lower level for
either route. It just takes some quick lane changes if you take the "wrong one". For example, I've personally driven the upper level northbound (signed for I-10) while following I-35. No problem.

B-30's status as a separate highway (as opposed to merely local lanes for AP-7) is kind of confusing.

Not even me. I don't even consider two highways running on parallel separate lanes to be concurrent. I consider a concurrency to happen only when a single piece of pavement is assigned to two different highways.

If you've read anything above, the OP is referring to same right of way, but specifically barrier separated.
