I found one that surprised me the other day. It's a junction if what are basically two farm roads in a plains state.

SW Ohio Street Road & SW 20th Street in rural Kansas, just west of El Dorado.
Might be because of terrain, so the north-south road doesn't have to dip down too much.

I discovered this one a few weeks ago as part of my ongoing exploration of paved county roads in Sedgwick and the surrounding counties.  At the time I suspected the grade separation was built when this length of SW 20th Street was still part of K-254.  However, while HistoricAerials.com is not being cooperative at present, I can find no evidence this intersection was ever on K-254.  The 1959 aerial photo (oldest available) shows it as a flat intersection while, just to the west, the road that Google Maps now shows as "Old K-254" swings north to converge on the current expressway alignment of K-254.

In the old days, when it was still a two-lane state highway, K-254 was on top of the east-west section line road known as 61st Street North in Sedgwick County and SW 20th Street in Butler County, and ran straight through Benton and Towanda.  This is largely still true of the expressway relocation, which was built in the mid-1990's, except that both Benton and Towanda are now bypassed with "Old K-254" former alignments.  However, the 1959 aerial shows that K-254 swung north in Towanda (well west of Ohio Street Road) to enter El Dorado along Central Avenue, and I suspect this was its original alignment since the K-254 designation was created in the mid-1950's.  (Side observation:  east-west county road numbering in Butler County is based on north/south distance to Parallel Street, which overlaps the Fifth Standard Parallel South and continues in Sedgwick County as 77th Street North.  The bulk of K-254 runs parallel to it but two miles south, while Central Avenue in El Dorado is also parallel to it but runs half a mile south.)

As for the grade separation at SW 20th Street and Ohio Street Road, this can have been built only by Butler County, though why it was done is a bit of a mystery.  There are a few clues, though.  The 1959 aerial shows Ohio Street Road making a spread-out wye on the south side of SW 20th Street, while the 1979 topographic map shows pavement on Ohio Street Road ending at the wye--north of it, it was just gravel.  The 2002 aerial shows the grade separation in its current configuration and Ohio Street Road paved all the way north to its current intersection with relocated K-254.

I suspect that the northern mile and a half of Ohio Street Road was paved as a complement to the K-254 relocation and widening.  It is uncharacteristically extravagant for Butler County to put in a grade separation instead of a four-way stop, and this may have been done to avoid creating new stop conditions for straight-through traffic on SW 20th Street.  (There would have been pre-existing stop signs on either arm of the wye for northbound traffic going from Ohio Street Road to SW 20th Street in either direction, but these would have affected turning traffic only.)

Ohio Street Road gets its internally redundant name from the fact that it is the county road extension of Ohio Street in Augusta.  It is currently a convenient paved shortcut between US 54 and K-254, though using it entails some knowledge of Augusta streets since it passes under the US 54 railroad viaduct instead of intersecting it on the level.  In time it will become much less convenient because Augusta has no meaningful planning control and is sprawling north along Ohio Street.

North Parkway/TN 1 at North Watkins Street in Memphis (probably due to the ex-railroad overpass nearby that is now part of a greenway rail trail)

Also East Parkway at Union, which lacks a railroad excuse. (There's also a half-interchange at East Parkway at Southern, but that's necessitated by the railroad line overpass.)

There's also the rampapalosa involving Union, Union Extended, Flicker, Poplar, and Walnut Grove just to the east, which is ridiculously elaborate given the contemporary traffic volumes.

The most pointless Memphis-area example, though, is probably Perkins at Winchester, where the low-volume road gets the overpass. Amazingly, MPO wants to rebuild it... but just to widen Winchester underneath. At the very least it should be SPUI-fied.

Calaveras Blvd. (CA 237) and Main St. in Milpitas, CA connect via a folded-diamond interchange; the Calaveras/237 bridge over Main Street also crosses over the UP Milpitas branch RR line as well as the under-construction BART San Jose extension.  Many years ago there used to be a terrific BBQ joint called Quincy's on Main St., essentially under the bridge; it's now unfortunately closed. 

CapeCodder

Lindbergh Blvd at Olive, which is MO 340. There are others at Watson, Page, Midland, and St. Charles Rock Road (MO 180).

I think Maryland routes 150 and 151 in eastern Baltimore County. Also, U.S. Route 40 has a lot in Baltimore and Harford counties, and I would even throw in Harford's Bel Air Bypass (U.S. Route 1) because while it has an interchange at Maryland Route 24/924 north of Bel Air, it also has a traffic light where MD-24 splits off to head into the Bel Air retail area, and toward I-95 and Edgewood.

Here's one in Youngstown, Ohio, just north of Youngstown State University in an old industrial section of town.

Intersection of McGuffey Rd. (US 62 on that stretch) and Andrews Avenue, grade separated both for terrain and other use (railroad tracks, creek).

You're just like crosstown traffic

Anybody else catch the "ghost ramp" within the 1/2 cloverleaf of US-62 & US-422?  I wonder what purpose that would have been for?

dgolub

There are a whole batch of them on Long Island, especially in Suffolk County.  For example:
* Jericho Turnpike (NY 25) and Hillside Avenue (NY 25B)
* Jericho Turnpike (NY 25) and NY 106/NY 107
* Sunrise Highway (NY 27) and Merrick Road (Nassau CR 27)
* NY 110 and NY 109
* Woodside Avenue (Suffolk CR 99) and Waverly Avenue (Suffolk CR 61)
* Patchogue-Mount Sinai Road (Suffolk CR 83) and Bicycle Path
* Captain Daniel Roe Highway (Suffolk CR 111) and East Moriches-Riverhead Road (Suffolk CR 51)

I haven't included any of the interchanges on Nicolls Road (Suffolk CR 97) or Cross River Drive (Suffolk CR 105) because those are expressway-like enough that I wouldn't necessarily classify them as conventional roads.

New York has quite a few. Some are due to terrain or railroad tracks, but others don't have a purpose other than to remove cross traffic. Other than those mentioned downstate, here are a few notable ones:

-3 on US 20 between NY 98 and NY 19, inclusive. All of these date to when US 20 was upgraded in the 1930s.
-NY 2 at NY 22. Just to the west of here, NY 2 descends from the Rensselaer Plateau, so the bridge reduces the grade for through traffic.
-2 on NY 9H in Kinderhook/Valatie.
-NY 9G at NY 308 in Rhinebeck. This one has no obvious purpose whatsoever.

SR 42 and the Powers Highway, both 2 lane highways, are connected with an interchange.

US 101 and SR 18 just north of Lincoln City has the same deal.

North of Gold Beach on 2-lane US 101 is an interchange that hooks up with the street going into the Rogue Hills development.

US 101 is THE backbone of the Pacific coast from Bandon OR to Willits CA.  Industry, tourism and local traffic would be gone or severely crippled without it being in functioning condition in BOTH states.

Academy Blvd & Platte Ave in Colorado Springs:

Academy used to be CO 83 until it was relinquished to the city, and Platte used to be US 24 before the bypass was built to the south.

US 24 & Manitou Ave on the east side of Manitou Springs:
