This is pretty crazy CT-137 (High Ridge Road) and the Merritt Parkway (CT-15). Did I mention it has a jughandle? https://maps.google.com/?ll=41.111127,-73.546396&spn=0.003605,0.007639&t=h&z=17

The Parkway is a non-conventional road. 
Take the road less traveled.

Another one in Indianapolis.  Kind of a strange setup:
Madison Ave and Morris St. http://goo.gl/maps/3OMkm

^^^

No expressways in sight, and direct driveway access to the mainline and even the ramps!  Great find!
Wait, it's all Ohio? Always has been.

what would someone's address be?  "12345 121EB-to-69SB Ramp"?

Nope.  101 Hwy 121.

I was just thinking about this topic and coincidentally this old thread popped to the forefront.

Foy Ave and Lycoming Creek Rd. near US 15 in Williamsport, PA. The connection is sort of a modified trumpet if you look at it a certain way.
http://bit.ly/11zAFzW

For about 20 years, Foy Ave was the terminus of the US 15 freeway, and traffic was funneled here to and from Lycoming Creek Rd. Apparently even before that, these ramps served as an interchange between the now decommissioned PA 828 (Race St.) and US 15 when US 15 followed High St. through town.

One that hasn't been mentioned yet:  MN 55 at MN 28 near Glenwood.  A diamond interchange between a couple of 2-lane rural roads.

75th St & 77th Ave in Kenosha, WI.

I doubt that interchange would exist if it wasn't for the railroad tracks on either side of 77th, but it does appear WisDOT could have brought WI 50 back down for an at-grade intersection.

Hampton Roads has a ton of these, although some may argue that these roads are expressways here.

VA 134 and US 17 near Tabb, a trumpet.
VA 134 and VA 172 near Langley AFB, a trumpet that was recently upgraded to a half clover.
US 258 and La Salle Blvd near Langley AFB, also a half clover.
US 258 and VA 278 in Hampton, a diamond.
US 17/258 and US 60 right before the James River Bridge, a half clover.
VA 105 and US 60 near Ft. Eustis, a half clover.
US 13 and US 58 in Virginia Beach, a SPUI.
VA 168 and VA 246 in Chesapeake.
US 13 and VA 168 in Chesapeake, a full cloverleaf.
US 13 and US 460 in Chesapeake, a partial clover.

When was this upgraded to a SPUI? It's been a few years since I've been on either Military Hwy or Va Beach Blvd, but I recall it being a standard diamond.

Just thought of two in Kingsport, Tenn. US 11W and TN 36 (formerly US 23) and 11W and TN 93.

It was a tight cloverleaf. Per NBI it was SPUIed in 1999 (it's actually in Norfolk, not VA Beach). Note that neither the Goog nor OSM shows it as a SPUI, but it seems to be one in street view.

More properly a 6-ramp partial-cloverleaf.

QuoteVA 105 and US 60 near Ft. Eustis, a half clover.

More than that.  It's effectively a cloverleaf with a semi-directional ramp from WB 60 to WB 105.

QuoteUS 13 and VA 168 in Chesapeake, a full cloverleaf.

Not full.  Missing a ramp in the northeast quadrant...gotta use a surface street to go from SB 13 to NB 168.

Norfolk, not Virginia Beach.  It looks like a tight urban diamond, but it functions as a SPUI where you can continue "straight" on the ramps.  SPUI's probably close on the date...it's definitely been that way since 2001 when I was first stationed in Norfolk.

Seeing Virginia mentioned reminded me of a couple:  Duke Street at both Telegraph Road and Van Dorn Street in Alexandria.

Yeah that's the configuration I've always remembered it being, I just never considered it a SPUI - and still don't.

http://goo.gl/maps/7UAwn
I don't recall how the signal phasing is set up, but it looks from the setup and the cars in the aerial imagery (streetview's too low quality) that the signals are set up just like a standard diamond.

In my book, if it's signaled like a diamond, and allows straight movements like a diamond, it's a diamond.

It's a SPUI if left turns can be set to go simultaneously. Straight movements have nothing to do with it.

Looks like one to me.

Yeah, old-style SPUI along an old-style urban quasi-expressway/super-avenue. Several examples of this can be found around St Petersburg, Florida.
