What're some highways that multiplex with the highway that eventually terminated them?
For example, I-94 meets I-90 in both Chicago and Madison, and later in Montana, I-90 is the western terminus for 94.
CA 1 is carried by US 101 multiple times and terminates at it in Leggett.
Another example is US-10 meets I-94 in the twin cities and 94 ends it in Fargo
M-26 duplexes with US 41 in Houghton/Hancock and terminates at US 41 in Copper Harbor.
MN 27 duplexes with MN 28 in Little Falls and then terminates at MN 28 near Beardsley.
US 1 multiplexes with I-95 many times, and then terminates it in Miami.
WI 42/57 in Door County
- US 23 overlaps I-75 in a few places and then terminates at the latter in Mackinaw City, MI.
- US 141 overlaps US 41 north of Green Bay and then terminates at the latter just outside of Covington, MI.
- I-43 overlaps I-41/US 41 near Milwaukee then terminates at the latter in Howard. For the double up, I-41 overlaps I-43 near Milwaukee and then terminates at the latter in Howard as well.
- M-72 overlaps M-22 in Traverse City and then terminates at the latter in Empire.
MO 14 meets US 60 in Billings, leaving the route after a short concurrency, only to end at US 60 in Marionville.
US 127 has a concurrency with US 27 in Cincinnati, and terminates at US 27 in Chattanooga.
IL 4 and IL 13 have a concurrency between Tilden and Marissa. IL 4's Southern end is at the IL 13/IL 127 concurrency between Vergennes and Murphysboro
I-55 and US 51 are concurrent around Bloomington, IL and south of Jackson, MS until Crystal Springs, and approaching I-55's Southern end in LA. I-55's Southern end is at I-10, and US 51 continues on south
US 51 terminates I-39 on both its Northern and Southern ends, and I-39 is 99.99% multiplexed with US 51 in IL
US 90 starts at I-10 in Van Horn, TX, and later is concurrent with I-10 in San Antonio and eastern Houston.
Route 33 starts at I-5 near Tracy, then runs concurrent with I-5 near Coalinga.
Route 99 starts at I-5 in Wheeler Ridge, then multiplexes with I-5 between US 50 and Natomas in Sacramento.

Yes, but neither does I-55 terminate at US 51 there nor does US 51 end at I-55. They are concurrent nearly to their southern ends but they don't terminate at one another.

Does not I-55 end at the gore-point here? The Left is I-10 EB, the Right is US 51 SB/to I-10 WB
No. I-55 ends at the actual merge/diverge with I-10 proper.
41 the Interstate terminated with the US route just after crossing into Illinois.
US-20 multiplexes with SR-113 from Rocky River (Cleveland) West to Elyria. The two routes split until the Western terminus of SR-113 meets US-20 in Bellevue, OH.
US 130 has both its southern terminus and a concurrency with I-295.

OH 2 begins at US 20 in Lake County, then they multiplex from Cleveland out to Rocky River. Interestingly enough, OH 2 also multiplexes with Alternate US 20 west of Toledo (though not at its termini).
US 91 has a decent length concurrency with I-15 in southeast Idaho before ending at it near Brigham City, Utah.
US 60 is concurrent with I-10 around downtown Phoenix, leaves the interstate for Wickenburg, to later go southwest to terminate at I-10.
In Virginia:
VA 5 overlays with US 60 twice and also ends at US 60
VA 63 overlays with VA 83 then later ends at VA 83
VA 2 overlays with US 1 Bus then later ends at US 1
VA 200 overlays with VA 3 then later ends at VA 3
VA 92 temporarily does this with US 360
VA 20 does this with US 15
US 221 does this with US 460
VA 131 does this with US 460 Bus
VA 337 does this with US 58
VA 309 sorta does this with US 29
US 522 does this with US 11 and US 15
US 60 in runs concurrent with I-10 for several miles in the Phoenix area. It then splits off and eventually terminates at I-10 near the town of Quartzsite.

US 127 has a concurrency with US 27 in Cincinnati, and terminates at US 27 in Chattanooga.
Nope. It's unsigned, but US 127 continues past US 27 and terminates in downtown Chattanooga.
Here's an example -- US 60 and US 460. US 460's western terminus is in Frankfort. It has a short wrong-way concurrency with US 60 in downtown Mt. Sterling, then terminates at US 60 in Norfolk.
MN 23 runs with I-35 between Hinckley and Sandstone, then ends in Duluth at I-35.
MA 28 is concurrent with US 6 through Buzzards Bay and ends at US 6 in Orleans.

US 90 starts at I-10 in Van Horn, TX, and later is concurrent with I-10 in San Antonio and eastern Houston.
That's almost true. You might say it's effectively true. But it isn't technically true. According to TxDOT, US 90 starts at BI 10 D, the Interstate business route. Years ago it was US 80, which was the logical place for US 90 to start. Nothing in the designation file specifies that the beginning was moved to I-10, even after US 80 was moved there. The signs going north from I-10 say it's SH 54, while the signs going south from Broadway say it's US 90. But the authoritative map, the Statewide Planning Map, shows the section between I-10 and Broadway as US 90.
OR 34 is concurrent with US 20 through Corvallis, OR only to terminate at US 20 in Lebanon, OR
US 13 concurs with US 1 and eventually ends at it in Morrisville, PA.
NY 3 really whiffed this exercise by continuing beyond NY 104 to end at NY 104A in Sterling. It's got the multiplex with NY 104 in Mexico and then the junction outside Hannibal, so if it wasn't for that extension, it would be a perfect example.
NY 13/US 11 is another almost-example. You've got the multiplex in Cortland and then the crossing in Pulaski that would be a conceivable spot for NY 13 to end... but nope, it continues to Port Ontario, where it ends (fittingly) at NY 3 instead.

OH 2 begins at the OH-IN state line, SW of Hicksville. It is IN 37 on the Indiana side of the border. It meanders a bit, multiplexed with US 6 and some other state highways before reaching US 20A.

...and just when I thought I'd found the most egregious almost-examples possible, here's another:
NY 324 and US 62 have the multiplex north of Buffalo, then NY 324 joins I-190 and makes it all the way across Grand Island on a collision course with US 62, only to exit and terminate at NY 384 less than a mile away.
Here on Long Island, NY 25 and NY 25A are multiplexed for a little while in Smithtown. Later, NY 25A ends at NY 25 in Calverton.
Then US 41 ALT in TN-KY should count as it concurs with its parent through Nashville and ends at its parent at both ends.
How about I 95?
Starts in Miami at US 1 and does the 1-9 multiplex across the GW bridge into NYC

and historic, US-127 terminated at the Junction of US-27 (todays US-127) near Lansing MI.
I knew there was one of these in Nebraska, but it wasn't anywhere I've actually been. NE 7 overlaps US 183 from the Long Pine area over to Bassett (along US 20), then ends at US 183 south of Springview.

Maybe. Florida changed the alignment of US 1 so now it has a short overlap at the southern section of I-95. Does that still count for the purposes of this thread?

Not sure, but if it does, that means I-75/I-640 in Knoxville is also an example because I-75 (and I-40) are through routes while I-640 ends. Same with I-80/I-294 in IL and I-41/I-94 in WI.
US 19 does as in GA it concurs with US 41, but it ends at US 41 in FL.
US 301 concurs with US 41 also in Bradenton, but terminates at it in Sarasota.
US 441 concurs with US 41 between High Springs and Lake City and ends at it in Miami.
Florida has another. US 23 in Jacksonville. Concurs with US 1 from north of Alma, GA to Jacksonville and then ends at US 1 in Jacksonville.
I-64 formally until I-70 was rerouted on the Stan Musial Bridge. I-64 was duplexed with I-70 in East St Louis IL then later it ends at I-70 in Wentzville MO.
Does I-676 in NJ count? The way it is signed from I-295 is like the two are concurrent from the end at I-295 in Bellmawr to the Walt Whitman approach in Gloucester City, even though you would figure that I-676 ends at I-76 at the bridge approach.
NY 33 overlaps NY 5 in Batavia, then later terminates at it in Buffalo.
US 24 and 6 have a concurrency in Ohio, but 24 terminates at 6 in Mintrum, Colorado. US 87 has a concurrency with I-25 in.. well pretty much everywhere, but 25 terminates at 87 and I-90. It's the opposite for 85 with I-10.

Was I-64 finished to Wentzville/I-70 before I-70 was routed on the Stan Span?
Now they bump in East St Louis, and then 70 terminates 64 in Wentzville

From a search on Google Maps, I-64 was on I-70 exit 210's signage since 2009. The Stann Musial Bridge was finished in 2014.
Another for Wisconsin: US 53 and WI 35 briefly overlap in La Crosse and later around Holmen, then ends at US 53 (and I-535) in Superior.
A California example I just saw on Google Maps:
Route 38 begins at Route 18 west of Big Bear Lake, then have a wrong-way concurrency in the town of Big Bear itself on the east shore. This was actually created in the 1960s after then-Route 30 was cut back west towards Running Springs (and eventually rerouted south towards Redlands on what is now Route 210).
Route 1 and Route 35 (and its predecessor Route 5, from 1957 onwards) had a brief concurrency in Daly City from today's Route 1/Route 35 junction north to John Daly Boulevard, before 35 continued north then east to end at Route 1 in SF.

In an example about as far away from both the other NY state examples as possible, NY 26 overlaps NY 12 in Lowville before terminating at it in Alexandria Bay.

Wait what? US 85 ends at the Mexican border. And 87/25 isn't really a fair example seeing as 87 is actually concurrent with 25 at that point...

Yeah this probably wasn't a fair example, But
technically, I-25 terminates at 85 and 87. along with I-90 and I-10.
US 64 in NC with US 264. 264 terminates at US 64 in Mann's Harbor (just west of Manteo) but the two routes multiplex with I-87 coming out of Raleigh to Zebulon before parting ways. Both highways used to terminate at US 158/NC 12 in Nags Head, but they truncate 264 some years ago.
M-35 is concurrent with US-41 (in Escanaba area) and ends at US-41 west of Marquette.
M-26 is concurrent with US-41 twice (1. the lift bridge between Houghton and Hancock) (2. between Laurium and Phoenix) before ending at US-41 in Copper Harbor - only the first concurrency was noted above.
US-23 is concurrent with I-75 three times (1. at Macon GA) (2. a short reverse-direction concurrency on the south side of Toledo) (3. from Flint to Standish) and terminates at I-75 at Mackinaw City. This was noted above, but these are the details.

NY 218 with US 9W between Highland Falls and Cornwall in New York.
