Roads that cross but never intersect

[bugo]

AR 352 crosses I-40 twice between Ozark and Clarksville.  It "blows it off" both times.  352 doesn't have an interchange with 40.  Are there any more examples of this?

US-6 and I-80 in Illinois.  They do meet at the two ends of the states, once in the Quad Cities, once in the South Suburbs, but blow each other off in between, and even parallel within a quarter mile at times without mention on I-80 (with the exception of the I-355 interchange).

US 41 and I-275 in Tampa cross without interchange after paralleling each other for a distance and blowing each other off just north of the city.  Only at the south end of their close alignments does US 41 South even get mentioned on the US 92 exit sign for I-275.

Parts of US 13 and DE 1 cross each other many times without interchange with both roads being right next to each other splitting apart for only 1/4 mile where this happens.  Only around Smyrna does the two roads interchange as at that point the two alignments drift a mile or more away from each other.

CT 22 and CT 40 (the latter being a freeway) cross twice, but no interchange.

I-880 and CA-87 cross near the San Jose airport.  Both are freeways but there are no ramps connecting the two.

[Takumi]

I can think of several on I-64 in Virginia alone: VA 157, VA 33 at Highland Springs, VA 173, VA 152, VA 351, and US 58 just north of the I-264 interchange. Also VA 415 and I-664, and I-95 and VA 208.

Route 83 and Route 210 in Upland, California (as the interchange for 83 was never constructed).

A few of México's toll roads have the corresponding free roads cross over/under them multiple times without interchanges.  I don't have a complete map yet, but I suspect the new 40(D) between Durango and Mazatlán is going to have a LOT of these.  Already, I see at least eight on Google Maps, and the whole road isn't even shown yet.  Some of these are where the new toll road actually goes under the old free road in a tunnel.

Illinois has several other instances similar to this as well. I-70 and US 40 parallel each other and have a couple of exits, but in between the two roads meet a couple of times without interchanges. I-74 and US 150 do the same thing-they cross near Farmer City without a direct exit(although there is a nearby one at IL 54) and they do finally cross with 2 direct interchanges at Danville.

There are more instances of this on toll roads because of the limited exits on toll roads. K-99 for instance crosses the I-335 portion of the Kansas Turnpike 3 times north of Emporia without an exit.

I would expect there are many thousands of examples of roads that cross Interstates without intersecting them; many hundreds if we count only state-numbered highways and above. One famous example is NY 90 and I-90, notable because the numbers are identical.

[US12]

US 23 and the Ohio Turnpike near Toledo cross, but have no ramps.

[jdb1234]

Florida's Turnpike and FL 417 near Orlando cross but there are no ramps.

[golden eagle]

US 80 & I-55 just east of Jackson don't intersect. Also, there are two interstates in Ohio that don't either.

[PurdueBill]

The Ohio mention probably refers to I-271 and I-80/Turnpike.  One needs to use either I-77 or OH 8 to make the connection.  (Or OH 303 and I-271 if one must.)

[MrDisco99]

Plenty of ignored freeways along the old turnpikes in the northeast.

Ohio Turnpike: I-275, I-271, OH 11
Penn Turnpike: PA 28, US 219, I-81, I-95
NJ Turnpike: NJ 42, I-295
Mass Turnpike: I-391

Also, Florida's Turnpike and I-95 blow each other off twice.

Probably you mean 475, not 275, but those are also ones that the Ohio Turnpike does not directly interchange with, although at least with 475 there is an exit nearby that makes a Breezewood connection.

Street View of the Turnpike westbound in that area is absolutely brilliant!!!  Why did they bother?

[OracleUsr]

I-77 at US 64 in Statesville. Granted, you can take I-40E one mile and get on 64.

[US71]

IDOT is changing this, but I-57 and I-294 near Chicago.

AR 282 (Mountainburg segment) crosses I-540 twice, but never intersects

[kphoger]

Can we limit the list to highway pairs that blow each other off more than just once?  Otherwise, as already noted, the list will be unthinkably long.

[ftballfan]

I-75 doesn't have an interchange with M-72 in Grayling.

[PHLBOS]

Penn Turnpike: I-95

That one will be changing in a few years; however, one can add I-81 to the list (one needs to use US 11 for a connection).

NJ Turnpike: I-295

True for the PA Turnpike (Future I-95) Connector, not true for the mainline NJ Turnpike; the 2 roads connect near the Delaware Memorial Bridge.

Add NY Thruway (I-87) & I-84 to the list as well.

In PA, I-476 (the Blue Route) and PA 320 cross each other 4 times but have no direct interchange.  I-476 also crosses PA 23 but has no direct interchange to it; one needs to use feeder ramps at the I-76 interchange south of the actual crossing.

[signalman]

Add NY Thruway (I-87) & I-84 to the list as well. 

Add it to what list?  They have a direct connection and have for a few years

[hobsini2]

A couple of times in Western Wisconsin US 12 and I-94 do not have an interchange. Once at Menominee and once more north of Tomah.

[sr641]

US 35 and Interstate 71 don't ever intersect.

[PHLBOS]

Add NY Thruway (I-87) & I-84 to the list as well.

My bad.  That interchange fully opening in 2009 predated my joining this site.  I was last in that area around 2002 and had to use NY 300 to get from I-87 to I-84.
