Here in CT we have a couple signs like this where a left on-ramp is place next to a right off-ramp.

Here.https://www.google.com/maps/@41.7536272,-72.6464466,3a,23.4y,172.36h,85.21t/data=!3m6!1e1!3m4!1s3nze6cKgqIoXRwlTm5Ux_Q!2e0!7i13312!8i6656

Curious to see if other states do this.

Prior to reconstruction of the Zoo Interchange in Milwaukee, there were signs on the prior on-ramps saying do not cross to the left-hand exits.

Westbound I-20 in Texas, as it merges with the southern/eastern end of I-635 and approaches the interchange with US 175, comes to mind:

In my opinion, this type of control would be better achieved with a physical barrier than a regulatory sign.  I have to wonder how strictly this is enforced.

[jakeroot]

Couple examples on I-5 in Snohomish County, WA. All for HOV lanes to prevent weaving.

NO HOV EXIT TO [WA-525] [I-405]

[HOV] NO ACCESS TO EXIT 189 [WA-526 WEST]

edit:

Another one in Seattle I forgot about: [NO EXIT TO OLIVE WAY ... ILLEGAL TO CROSS DOUBLE WHITE LINE]

[ibagli]

There's one in Columbus on OH-315 southbound, to stop traffic from trying to cross traffic entering from I-670. There also used to be one on I-71 southbound right before I-70, regarding an exit that has since been reconfigured.

[MNHighwayMan]

There used to be one of these in Arden Hills, MN, on the ramp from Snelling Ave SB to EB I-694, preventing immediate exit onto Lexington Ave. However, reconstruction of that section of I-694 in 2012/2013 eliminated that movement from Snelling to I-694 entirely.

Luckily there's one high-resolution series of GSV images showing the sign.

Found another one just south of downtown Columbus on I-71 from OH-315 southbound...

Along the Bayshore Freeway/US 101 in San Francisco, traffic coming in from the left hand side onramp from I-280 south is specifically directed not to merge multiple lanes into the Paul Avenue exit, but to use the following exit after that (Cow Palace/3rd Street/Bayshore Boulevard).

There used to be a few more around DFW that have been eliminated with all the freeway re-construction. 
The old Ft. Worth 'mixmaster' had several left and right exits/merges; traffic entering from northbound I-35W to westbound I-30 had signage telling them not to exit to Jones St. I saw that one being ignored so often I wondered why bother to sign if it (apparently) wasn't enforced.

[signalman]

I can't think of an example of any such signage in New Jersey.  However, I can think of a local example with a physical barrier that prevents motorists to even attempt crossing I-287 in order to access either Parsippany Rd (CR 511) or Entin Road/Sylvan Way.  https://www.google.com/maps/@40.853703,-74.4235827,3a,76.6y,193.16h,83.27t/data=!3m6!1e1!3m4!1s16Qv5TfzFAKQRgRuQoWOFg!2e0!7i13312!8i6656.  I'm sure NJDOT is well aware that people wouldn't adhere to any such signage, so instead they just use a Jersey barrier.  The linked ramp is from I-80 WB to I-287 SB.  The above movements can be made via a local exit ramp, however, signage doesn't indicate such.  One must have some local road knowledge.  I also assume GPS would route a driver this way who wishes to access any of the above listed roads.  Since I don't use GPS myself I am merely guessing here and have no first-hand knowledge.  The local ramp I alluded to: https://www.google.com/maps/@40.8633576,-74.4100262,3a,75y,280.4h,77.38t/data=!3m6!1e1!3m4!1sjMj3IQH4KS16gg-9BOPR9Q!2e0!7i13312!8i6656
  And at the gore: https://www.google.com/maps/@40.8657104,-74.4137958,3a,75y,295.06h,90.57t/data=!3m6!1e1!3m4!1s8HVcgdgH75AVM45zjaIadg!2e0!7i13312!8i6656

The ramp from I-291 west to I-91 south has "Access to Exit 7 Prohibited" signs.  As part of the Springfield Viaduct project, these signs have been supplemented by a Jersey barrier between lanes, which now makes it physically impossible for traffic to go from this ramp to Exit 7.

I thought there was a sign like this on I-35W SB south of downtown Minneapolis.

[MNHighwayMan]

I thought there was a sign like this on I-35W SB south of downtown Minneapolis.

There may have been at one time (not sure where it would've been…), but chances are it's probably gone now with all the construction (past or present) on I-35W.

[hbelkins]

There once was one on I-75 northbound in Cincinnati approaching I-74. I think the ramp was for I-74, but it used the grade of I-75 and there were signs saying "No Access to I-75" with there being no physical divider, only a thick white painted line. I"m not sure if this is still the case or not, as I haven't been on that section of I-75 in years.

That section of I-75 was majorly overhauled a couple years ago and that sign (and the need for it) have gone away.

The Inner Loop of the Capital Beltway (I-495) at I-66 (old Exit 9, now Exit 49) long had two exit ramps, one on the left and a loop ramp further along on the right. (The left-side ramp was the original exit, though it was reconfigured over the years.) Traffic entering at the previous interchange (US-50) saw a ground-mounted BGS telling them (but not requiring them) to use the right-side exit, this because using the left exit required changing across four lanes of traffic in under a mile. Didn’t matter: More than 75% of drivers forced their way over to the left-side ramp. The HO/T project solved the problem because the left exit is now for the HO/T lanes only and people entering from Route 50 have no access to it.

No Google Street View available—it goes back to 2012 a few months before the HO/T lanes opened and by then access to the left exit was closed during the construction.

You got to most of the ones I was going to use, except:

◊ NO EXIT TO [SR-518] BURIEN SEA-TAC AIRPORT

[lepidopteran]

There used to be one like that in Dayton, OH, on I-75 SB.  The on-ramp from Keowee St. had a black-on-white sign (IIRC) that read something like "No Exit to [SR-4 shield] Webster St.", since the Route 4 was a left exit at the time.  I'm not sure, but I think there was a similar sign for SR-4 traffic heading into I-75 SB (on the left) to not get off at Main St./SR-48.  In any event, since the infamous "Malfunction Junction" interchange was completely reconstructed, the sign is long gone because (1) the SR-4 ramp was moved to the right-hand side, and (2) the Keowee St. ramp was eliminated altogether.

[NE2]

I think I've seen these in Nashville.

Ahh, of course. That's only the one I see the most.

[txstateends]

A ramp to I-45 in downtown Dallas has a small sign before you get on to I-45 (a left-side on-ramp, BTW) about not exiting to I-30.

I always found this one interesting because I-20 WB traffic cannot access one of its own exits. Although historically, 20 was on what is now 635 headed southwest.
