Title probably makes no sense, but here's an example. I-39/90 and US-51 in southern Dane County WI:
https://www.google.com/maps/@42.9211345,-89.0849446,2117m/data=!3m1!1e3
https://www.google.com/maps/@42.8722062,-89.0527147,2125m/data=!3m1!1e3
In both instances US-51 is splitting off to the left as you're going north, and to the right as you're going south.
MA 110/113 on the western side of Methuen, MA where the I-93 interchange is. MA 113 takes the northerly route and 110 the more southerly route on both sides.
I-93/US 3 in Franconia Notch, but only on a technicality as US 3 crosses under I-93 pretty close to the overlap, meaning it's not really that much of a bump.
US 1 and MA 1A in Salisbury/Newburyport MA; 1A hugs the ocean.
Probably the best example of the bunch: MA 122 and MA 140. Both are long NW-SE routes that span a decent chunk of the state; they overlap but never cross.
The I-80/90 overlap, however you want to look at it:
I-90 exits to the north in both directions - or - I-80 exits to the south in both directions.

I don't this is what the OP has in mind. As you head south from Madison on I-39/90, if you exit to the left at the first one, you are heading on US-51 North. If you exit to the left at the second one, you are heading on US-51 South.

Except that is the OP...
The I-70/I-76 overlap, which I find interesting because it's a little more nuanced but still meets the thread:
At both New Stanton & Breezewood, I-70 initially splits to the north of I-76 to pass thru the toll plaza and connect to its free alignment. Then once on the free alignment, it passes back under I-76 and ultimately heads off to the south of I-76.
MA 2A joins MA 2 from the north at the Concord Rotary and then splits from MA 2 at Exit 125 running north of MA 2.

LOL....yeah I guess so.

1. OP apologizes for giving the wrong example to his own question.
2. It's not possible for you to exit I-39/90 onto US-51 South twice along the same concurrency without turning around. That's just a basic law of every concurrency.
Both I-90/I-94 concurrencies
US 2 enters from the north side of I-90 and leaves (with US 395) on the north side.
I-84 and US 30 do this a few times, especially since the latter acts as a business route for areas away from the river while I-84 runs along the shore.
US-81 splits off of I-29 in North Dakota, takes a more western route, and rejoins I-29 further north in the state.
https://www.google.com/maps/@48.4781161,-97.2167747,9.71z
US-20 and NY-5 would count since the only times NY-5 is not north of US-20 are the two concurrencies.
CA 99 joins I-5 from the east in Sacramento and departs to the east just north of Sacramento.
I am noticing a trend: almost all of the submissions so far have been highways that are signed in the same direction as each other (both N/S or both E/W).
Are there any examples of highways that are signed in different directions?
(Also, a title suggestion, inspired by one of the earlier replies: routes that overlap but don't cross)

Both I-90/I-94 concurrencies
The Wisconsin one yes, but not the Chicago one since I-94 goes south of I-90 heading towards Indiana (and later crosses back to the north side of I-90 at Lake Station).

Although ironically it would qualify if it stayed overlapped with I-90 the whole time.

The I-44/55 concurrency (https://www.google.com/maps/@38.614706,-90.1992509,4633m/data=!3m1!1e3) in St Louis
US 36/OH 37 in Del.Co. Ohio

One in North Carolina probably won't be around much longer: US-70 along I-85 south of Greensboro. This is much shorter than it used to be when I-85 was previously routed through the Death Valley section of Greensboro. But if all goes as planned (and approved), US-70 was supposed to be signed along Wendover Avenue and then NC-68 from Greensboro to High Point, avoiding the I-85 multiplex altogether.

Oh, and I forgot that US-70 does it again south of Lexington where I-285 comes in. US-29 comes along for the ride as well.

US 60 and US 421 in Frankfort. Going west on US 60, US 421 north comes in from the right and then departs from the right (to be accurate, 421 continues straight and 60 turns left, but the general concept is the same).
Of course, those two routes have a brief concurrency in downtown Lexington where 60 crosses 421, but the Frankfort concurrency fits this category.
I-80/90 in Indiana and Ohio
US 89/91 between Brigham City and Logan UT
US 6/50 between Green River UT and Grand Junction CO
US 129/441 between Eatonton and Athens GA
US 78/278 between Thomson GA and North Augusta SC
US 74/76 between Chadwell and Wrightsville Beach NC

Technically, US 52 and US 78 north of Charleston SC since 52 is generally signed N/S where applicable in South Carolina, although neither route is really signed south of that concurrency...
I-80/I-94 is definitely one. On both ends, I-94 simply runs north of I-80, and at the eastern end, I-80 switches concurrencies with I-90.
US 1 and US 13 in Philadelphia, on Roosevelt Boulevard.
US 6 and US 322 from Conneaut Lake to Meadville.
PA 54 and PA 901 near Mount Carmel.
Historically, PA 54 and PA 61 from Mount Carmel, through Centralia, to Ashland...an example with roads signed in different directions. PA 54 was rerouted in the late 1990s to bypass Centralia and Mount Carmel, creating the above PA 54-PA 901 example.
Another example of roads signed in different directions, this time in North Carolina: US 23 and US 74 from Dillsboro to Clyde.
A same-direction concurrency this time: US 64 and US 74 from Cleveland TN to Murphy NC.
US 12 in the Gary, Indiana area forks off of US-20, takes a different street to IN-912 (Cline Avenue), enters Cline Avenue, and exits back onto US 20 leading into Gary.
https://www.google.com/maps/@41.6262102,-87.4438283,14z
US 20 and US 6 from Lakewood to Public Square in Cleveland, OH.
While Colorado signs concurrencies badly, there's at least a couple of examples here:
US 40/287 along I-70 from eastern Aurora to Limon
US 40 along I-70 (and technically US 6) from Empire Junction east to the foot of Floyd Hill (east of Idaho Springs)
It's a super-technicality, but US 87/I-25 works from Raton, NM through Colorado to Cheyenne, WY.
US 85 and I-25 also works on the north side of Cheyenne, WY.
US 30 and I-80 in Wyoming happens a couple times: from Green Bluffs to Cheyenne, from Cheyenne to Laramie, from Walcott to Little America. US 287 overlaps both I-80/US 30 from Walcott to Rawlins.

Cheyenne? 87 stays on 25 all the way up to Glenrock.
IIRC all of US 101's concurrencies with Route 1 in California have 1 splitting to the west and 101 splitting to the east.
Route 1 and Route 135 (former US 101 for most of it, but not in this section) in Orcutt split off in such a manner as well.
I-280 and Route 35 between San Mateo and San Bruno
Route 79 and I-15 in Temecula
