Limited-access highways that pass over each other without an interchange

What are some examples of two limited-access highways passing over each other without any type of direct interchange? Doesn't have to be Interstate, just limited-access.

Off the top of my head, I can think of:

  • Merritt Parkway and CT 40
  • I-76/PA Turnpike east of Harrisburg, which actually occurs twice: once at PA 283 and again at the Harrisburg Airport Connector
  • Ohio Turnpike at OH 11, I-271, and I-475
  • I-95 and Florida's Turnpike south of Port St. Lucie. While this technically also occurs twice, the flyover at Fort Pierce features an indirect connection.
(Edit: deleted examples of indirect access per refined topic question)

I'm sure there are others, those are the ones that immediately come to mind.

Clinched, plus MA 286

Traveled, plus several state routes

Lowest untraveled: 25 (updated from 14)

New clinches: MA 286
New traveled: MA 14, MA 123

I-95 and I-295 in NJ is interesting because I-95 crosses over its own child (which ends at it on both ends) without an interchange.

I-880 and CA 87, San Jose. There have been proposals for a partial interchange, but the location next to a river and airport makes it tricky.

  • I-81 and I-476/Northeast PA Turnpike
  • PA Turnpike at the transition point between I-76 and I-276, which passes over US 422
  • I-76/PA Turnpike east of Harrisburg, which actually occurs twice: once at PA 283 and again at the Harrisburg Airport Connector
  • Several other interchanges on the I-76/PA Turnpike mainline, where the actual interchange dumps you out on a nearby surface road (I-81, I-70/Breezewood, I-99, US 219, US 119, and PA 28)
  • Ohio Turnpike at OH 11, I-271, and I-475
  • I-95 and Florida's Turnpike, which also occurs twice: once in Fort Pierce and again south of Port St. Lucie

I feel like just about every closed/ticked-based toll road is going to have these somewhere, although I can't think of any on the Indiana Toll Road off the top of my head.  The Kansas Turnpike crosses three freeways where the connections are at least partially indirect (some more than others): US 54/400/Kellogg, K-96, and US 75.

We may have done this before, but ...

I-75 at US-30, Beaverdam OH - you have to get off the freeway and take a short section of the Lincoln Highway (OH 696).

I-71 and US-35 in southwestern Ohio.     Access is required via SR 435 - the old US-35 alignment.

NJ Turnpike and NJ 42.

I-87 and US 209.

NJ Turnpike and NJ 133 sort of.

I-57 and I-294 in IL.

I-57 and I-294 in IL.

For a long time, there was no interchange, but a partial one has been built. There are now SB->SB and NB->NB ramps.

Illinois: counties 100%, highways 61%
Michigan: counties 100%, highways 56%

The Kansas Turnpike crosses three freeways where the connections are at least partially indirect (some more than others): US 54/400/Kellogg, K-96, and US 75.

The KTA is currently constructing an interchange with US 54/400/Kellogg with a southbound exit and entrance to/from the west and a northbound entrance from the west.
K-96 is accessible from the turnpike via this: https://www.google.com/maps/@37.683113,-97.1959056,15z

Many of the movements will still be indirect, involving at-grade intersections.

I wouldn't count that.  Access between the two is still rather easy via the Crosstown...

Let me refine the topic question a bit: what are examples of two limited access roads passing over each other without any interchange whatsoever, even indirect movements via frontage roads? (i.e. only looking for Merritt Pkwy @ CT 40-like examples). This eliminates all of the PA Turnpike cases except for PA 283 and the Harrisburg Airport Connector, but the Ohio Turnpike examples remain since OH 11, I-271, and I-475 don't even have indirect access to the Turnpike (the turnpike doesn't even have an interchange at any of their surface or frontage roads).

Nah, cutting across that three lanes getting from SB 169 to WB 212 ain't my idea of easy. Especially when I'm trying to stay on 62 and have idiots buzzing across me on both sides!  :no:

The Ohio Turnpike signs To I-475/US 23 at Exit 59/US 20, and it is a very short jog onto Dussel Drive over to I-475, and the "missing"  connection between the interstates is well signed along US 20 and Dussel Dr

I-475/US 23 does not sign To OH Turnpike/I-80/90 for Exit 6/Dussel Dr, tho. To OH Turnpike/I-80/I-90 is signed at the end of the Exit Ramp/at the stoplight for the ramp on Dussel

Philippines examples:

C-5 South Link Expressway at Metro Manila Skyway, Paranaque.  (C-5 and Skyway are proposed to be connected not at this spot but via a different expressway route, the SEMME/Southeast Metro Manila Expressway).

NAIAX & SLEX, Taguig.  (NAIAX links to the Skyway but does not have any connection to the older surface-level highway.)

Similar one to that, with an access road connecting both ends of the US route and a diamond interchange with the interstate: I-70 and US 63 in Columbia, MO.

Florida's Turnpike crosses over I-95 at two separate points in South Florida (St. Lucie County) with no interchange.
