Highways that don't intersect with other signed highways

Here in Jackson, U.S. 80 doesn't intersect with I-55. However, I-20 is about a quarter mile away (though I'm just estimating the distance). Aren't there two interstates in Ohio or somewhere up there that don't intersect?

On the Ohio Turnpike (I-80) and I-271 don't have an interchange.  And, it's not just one of those "toll road things" either.

I've discussed this crossing on a different thread awhile ago.  I-80 at that point is on a grade coming in/out of the Cuyahoga River valley and I-271 passes under I-80 east and over I-80 west.

And, for the longest time, you couldn't get directly from the Ohio Turnpike to I-77, I-71, I-75, etc.

And, I know this has been done before, there are still many of these along the Pennsylvania Turnpike and Northeast Extension.

Due to limited ROW near San Jose International Airport, Route 87 and I-880 do not have an interchange.

Not too many examples of two numbered roads crossing without some sort of junction here in California...

Until a number of years ago, I-176 and the Pennsylvania Turnpike didn't have a direct connection.

And for now, I-95 and the Pennsylvania Turnpike don't have an interchange.

CT 15 and CT 40 share a zero-ramp interchange in Hamden.

I-295 and US-90 in Jacksonville, FL near I-10.  Limited space there.  However, the two will intersect on the other side of Jacksonville when FL-9A becomes I-295.

I-57 and 294 in suburban Chicago cross each other with no interchange, don't they?

Also, closer to home for me, the I-76/NJ 42/Atlantic City Expressway corridor (it's 42 at that point) and the New Jersey Turnpike.

The only freeway crossing without an intersection that I know was already mentioned (SR-87/I-880). 

I don't recall anything in Washington; however, there's a couple of highways in Portland, Oregon, off the top of my head.  There's no direct interchange to OR-99E from the Banfield (I-84).  Also, there's an offramp indirectly to SR-213 for EB traffic, but no such offramp exists for WB traffic.  Both are not freeways, though, but they are signed highways!  :sombrero:

US 6 crosses over I-180/US 34 in Lincoln without a direct connection. Access is provided just to the north at the Cornhusker Hwy. exit where US 6 is several blocks to the east.

Another one in Nebraska-US 385 does not have a direct connection with I-80. Access is provided by a short link at the Chappell exit. The best access though to US 385 heading north is by the link at the east Sidney exit.

Too many of these to count in Virginia, let alone other states.

US-6 seems to have a love-hate relationship with I-80 in many places.  Here's the crossings and near misses in Illinois alone:

Interchange with I-80/94 at Torrence Ave (Exit 161)
Within 1,000 feet at Marley
Interchange with I-355 less than one mile north of I-80
Crosses I-80 with no interchange just west of the Des Plaines River, between the river and Center St (Exit 131)
Turns away from I-80 in Morris, a block south of the interchange with IL-47 (Exit 112)
Parallels and then turns away from I-80 near Seneca, a block south of Exit 105
Turns away from I-80 a block south of the interchange with IL-89 (Exit 70)
Crosses I-80 without an interchange between Exits 27 and 33
Finally has an interchange with I-80 (Exit 9) just north of the Big X (I-74/I-80/I-280) in the Quad Cities

The distance between actual interchanges of I-80 and US-6 is 152 miles.

I-878 only has one ramp from I-678 north; other than that, the only other highways it intersects are NY 878 and reference routes.

No interchange either at the crossing NE of Fremont, OH

There's two more of these in California.  California 210 has no interchange with California 83 (Euclid Avenue) in Upland.  Down in Orange County, I-5 has no direct connections to California 261-TOLL.

IIRC, the neighborhood around that interchange asked for it not to be built, though the ROW was present for its construction.  I wonder if it'll always be laid out like that...

US 5 does not have an interchange with I-89 in White River Junction, VT. It does, however, have an interchange with I-91 right up the road, so one with 89 would be redundant.
If you always take the same road, you will never see anything new.

I know it doesn't really count, but CA-266 is only connected to the rest of the highway system in the state via a very rural intersection with CA-168. It's really more of a misplaced Nevada state route than anything else.

Troubleshooter

Beaverdam OH: US 30 and I-75 used to have a direct interchange before they moved US-30. Now both have interchanges connecting to the old US-30. A railroad running along I-75 at the point of crossing is part of the reason.

No connection between US 9 and I-95 at Perth Amboy NJ. It used to exist, but was removed.

Maryland 125 in western Baltimore County does not intersect any numbered route!

US-212 in Northeastern Wyoming doesn't connect with any Wyoming highways- it is entirely isolated

I suggested to the DOT to make an interchange here and they Whalley Ave and it's ramps were designed in a way to make up for the lack of interchange.  To me, it sounds like a classic case of expressway traffic clogging up side streets b/c of no connection between the two.  They didn't seem to interested in the idea either.  Strange!

Just doing state routes, only a few in Florida.

I-10 and FL 289 in Pensacola
I-110 and FL 742 in Pensacola
I-95 and FL 845 in Fort Lauderdale (too extreme of an angle)
I-95 and FL 710 in West Palm Beach (think this is slated to change in the future)
I-95 and FL 802 in Lake Worth
I-4 and FL 45 and FL 569 (removed a few years ago) in Tampa
US 92 and FL 539 in Lakeland
I-275 and Business US 41
I-75 and US 301 (for one out of three times)

That's about it.
So many roads...so little time.

I-15 in NW Arizona doesn't connect to any signed highways-it just passes from Nevada to Utah through the Virgin River Gorge.

You're really talking about signed highways that cross each other but don't connect (but each may connect to other signed highways).  The thread title implies we're looking for signed highways that have no connection to *any* other signed highways. 

Something like M-185 (Mackinac Island MI), for example.  HI 440 (Lanai Island HI) too, unless HDOT has signed tiny spurs HI 441 (Lanai City) and HI 443 (Lanai Airport) since I last visited that island.  Ditto the isolated fragments of AK 7 in Juneau and Ketchikan (and maybe signed in Petersburg too), unless you count the Alaska Marine Highway ferry connectiing those fragments to the non-isolated (connects to YT3) AK 7 fragment in Haines.
