I've found this to be a fairly rare instance but happens often enough to be noticeable. For instance, US 45 crosses I-64 out in the middle of nowhere in Illinois but there is an interchange. However, in other locations, there is no interchange.
Kentucky examples --
I-64 and US 31 cross in Louisville but do not intersect.
I-64 and US 421 cross near Midway but do not intersect.
I-64 and US 25 cross north of Lexington but do not intersect.
I-65 and US 150, US 31E and US 60 all cross in Louisville but there's no interchange. (US 31E is signed on an I-65 exit near Nashville, but the roads do not actually cross. Also, US 60 used to have an interchange when it was routed along I-264, and there is an interchange with Alternate US 60, but it does not count).
I-471 does not intersect US 27. The spur route south of I-275 that connects to US 27 is unsigned KY 471.
No examples for I-24, I-71, I-75, I-265 or I-275. I-275 does not intersect US 27 in Kentucky, but it does in Ohio.
No examples in West Virginia.
I-90 and US 7, I-90 and US 11, I-90 and US 62
In New York, I-87 crosses but does not intersect US 44, 202, and 209 (although 209 comes close).
I-20 crosses US 19, US 29, and US 41 all in Atlanta, with no direct interchange to any of them.
US-58 and I-64 cross without interchange in Virginia Beach.
Would you count US-30 and I-75 in Ohio? You have to go on Ohio 696* for about 1/4 mile to get from one freeway to the other.
* - aka Lincoln Highway, so I surmise this was once part of US-30. Perhaps when the US-30 freeway was built, it was felt impractical to build a direct intersection to I-75.
I-84 and US 5 in East Hartford, CT
I-91 and US 44 in Hartford: US 44 isn't officially part of I-84 when they cross (it's on a pair of exit ramps from I-84) , but it does join by the time the ramp from I-91 South to I-84 East merges onto 84.
I-71 and US35 in Ohio. Connection through OH-435
2 in Nebraska
1. I-180 and US 6 in Lincoln
2. I-80 and US 385 SE of Chappell
Just curious how US 63 and I-70 in Columbia, MO would count on this score.
I-95 and US 27 in Miami has no interchange. There's no "To US 27" signs anywhere. It's a bit of an oddity, since I-95 in Florida skips over very few state roads for exits, but the missing 27 has always been a weird one.
A) they're both going to terminate a few miles south/east in Miami anyhow.
B) the I-195 / FL 112 interchange built in the 1960s doesn't leave any room for an exit.
In NJ I-80 crosses US 202 without a direct interchange
Not quite Interstate, but US 30 and US 322 cross the NJ Turnpike without an interchange
I-75 and US 92 cross without any access. Further north US 301 passes under I-75 for a third and final time from the south, but this time without direct access. The two parallel each other through to Ocala before US 301 branches northeast for good.
US 41 crosses under I-275 in FL near the north end without direct access due to a parallel CSX Railroad line.

Yes there is. The westbound exit is a bit convoluted and requires one to use c/d roads and ramps, but it's a direct connection.

The Ohio US 30/I-75 and US 35/I-71 mentions are accurate now, but at one time they were not. The OH 435 current routing was once US 35 until the freeway was completed.
US-150 and I-57 cross once in Champaign, IL without an interchange. It also used to cross I-55 the same way before it was rerouted onto IL-9 and Mitsubishi Motorway in Bloomington-Normal.
US-52 crosses I-88 once without an interchange in Dixon, IL.

Yes for US 30.
No for US 322: Scroll down for NJTP Exit 2 BGS (http://www.alpsroads.net/roads/nj/i-95/2.html)
However, US 322 and I-76 (via the PA Turnpike) cross each other but don't intersect/change.
I-40 and US 31 (Eighth Avenue South) in Nashville, Tennessee. I-65 is multiplexed with I-40 at that point, but it does interchange with US 31 several times, and multiplexes with it at least once.
Kind of a two-for-one, I-80/90 (Indiana Toll Road) crosses US-35 without interchange near La Porte, IN.
Also, US-35 crosses both I-80 and I-90 (same spot, Indiana Toll Road) once without an interchange near LaPorte, IN.
US-127 does likewise for the Ohio Turnpike (I-80 and I-90 again) near West Unity, OH.
Ok, so obviously my post was poorly researched. Thanks for all the corrections.

There's one on-ramp from US Route 5 North to I-84/US Route 6 West. I'd imagine no other ramps were built due to a nearby flood dike wall immediately south of the interstate. Also, I-84/US 6's Exit 56 for Governor Street - East Hartford is already immediately after this heading west.
Not 100% certain about I-91 and US Route 44...but they come awfully damn close!

I-294 and US 45 in both Justice and Franklin Park Illinois
However, the crossing in Justice is an interchange. There are entry ramps to the southbound Tri-State from LaGrange Road.
Prior to the 1989-90 reroute of US 1 onto I-93 (& a short segment of I-95) in the Boston area; it crossed but did not interchange with I-90.
Not sure if this old MDC-spec'd BGS (https://www.google.com/maps/@42.3479287,-71.0920162,3a,75y,321.99h,78.52t/data=!3m7!1e1!3m5!1s_5Osvy0raU58hLxtFflFfA!2e0!6s%2F%2Fgeo3.ggpht.com%2Fcbk%3Fpanoid%3D_5Osvy0raU58hLxtFflFfA%26output%3Dthumbnail%26cb_client%3Dmaps_sv.tactile.gps%26thumb%3D2%26w%3D203%26h%3D100%26yaw%3D93.581245%26pitch%3D0!7i13312!8i6656) erected a few years prior to the reroute (but never revised) is still there.
The section of the PA Turnpike signed I-70/I-76 does this with both US-119 and US-219.
And at Bedford, there's US-220; you have to go a few hundred yards on Business 220 to get between the pike and I-99/US-220 proper. Also, in that same vicinity, the pike crosses US-30 twice -- and does so yet again east of Breezewood.
US 78 and I-459 in Birmingham, AL cross, but there isn't an interchange where they cross.

Even though there is no access from 294 to 45?
I-12 and US 51 cross but don't interchange, namely because of proximity to the I-12/I-55 interchange. However, a mile or so to the east, I-12 does interchange with US 51 Business.

Yes. There used to be a northbound exit ramp to 88th Avenue there, but it was removed some time ago.

I'd disagree on US 119 , US 219 and US 220. There are connections, although not direct, and the routes are signed on the Turnpike/I-76.
I-91 and US 4 in White River Junction, VT. Access to US 4 is provided via US 5 at Exit 11.
Does it have to be between an Interstate and a US Route? If not, I know of an example with 2 interstates.

I-275 crosses over US-50 in Milford, OH. Access is provided via OH-450 (formerly an unnamed pseudo-freeway). I think the original intention may have been to route US-50 on this pseudo freeway to en route to downtown Cincinnati.

That doesn't count, for two reasons. One is that access is provided, and IIRC, the exit is signed for US 50. Two is that the routes intersect on the west side of Cincinnati, at the only Indiana exit for I-275, and access there is also via an access road.

#1 is incorrect. It used to be signed for US-50, but now the BGS says OH-450 to US-50. The access road is signed OH-450 until you pass I-275 going Westbound and it turns into Milford Pkwy. So you have to take OH-450 East to get to US-50. You have to take OH-450 West to get to I-275.
#2 I will give you and I thought of that one. That is really just a long ramp to get to US-50.

Are we going to count I-87 and US 20? The southern stub of the Northway might be signed "to US 20", but there's an intermediate interchange in there and the stubs are over a mile long.

Would US-177 and I-44 count? There's no interchange there, but there's one a couple miles to the west along SH-66, which intersects US-177 not too far south of I-44.

I actually never knew that it was US 11 until a couple years ago. It's simply signed as "Virginia Avenue" and I never thought a dinky 2 lane road is US 11.
