Would the loop ramp for southbound US 17 at Opal count?

That is an arterial interchange, or the portion of an ultimate design for a full arterial interchange.

How would it be a "portion"? Where else would you add ramps?

Philippines is well known for having some streets with non freeway flyovers though.  In this case its Lazatin Blvd @ Jose Abad Santos Ave in San Fernando, Pampanga.

Here's one (though its merging on and not off) 3 mile Road merging with OR 18 at McMinnville, OR OR-18

Isn't that just a tight diamond interchange?

Las Vegas, NV:

Las Vegas Blvd northbound access to Town Square Pkwy (the Town Square mall/lifestyle center)

Boy that one really stands out as weird to me.  Look at the short taper opening...you better not think twice about getting over or not!  I also like that every person on that flyover went through a traffic signal about 500' upstream  :pan: 

Every time I see an aerial of NV I think it's immediately after a resurfacing and that's why it's missing pavement markings...but I guess they just don't often do the markings?  Not really a fan of that.

Panning around Las Vegas led me to this one, which replaces a diamond ramp with a flyover to the arterial: https://www.google.com/maps/@36.1005717,-115.1805034,219m/data=!3m1!1e3

Florida has been mentioned a few times but I haven't seen this one posted yet (the "echelon"):

I-49 connector

Isn't that a freeway?

In that area it's sort of 50/50.

The Fulbright Expressway is a freeway, but dumps off onto 71B.  Traffic lights close to the exit/entrance ramps, but nothing at grade after getting onto it.

In the style of a T-intersection with one flyover, there's one west of Denver for the left turn from Parmelee Gulch Road onto US 285 (Google Maps). It's the first major intersection west of the freeway portion of 285, which officially ends about two miles to the east; there are a few minor median breaks in between. It's unusual among the interchanges on the expressway portion of 285 for including a left turn off of the highway. 

More in the category of partial interchanges, here are two where a fork in the road comes with a grade separation:

  • Vasquez Blvd (US 6-85) and Colorado Blvd (CO 2) in Denver (GMaps); there's another interchange involving the same route numbers a bit further north, as well, but there's more going on
  • Venetucci Blvd (former US 85) & Willwood Rd in Colorado Springs (GMaps)
By the way, Venetucci Blvd used to be US 85 there before the swaps to get Powers Blvd onto the highway system, and US 87 used that road much further in the past. However, "US 85/87"  is shown on an odd little guide sign near the split as of June 2018 (attempted StreetView link).

Florida seems to love these; several have been mentioned already, handling heavy left-turn movements. In NYC, a couple come to mind that are actually fly-unders: NY 25 (Queens Blvd.) at I-278, and NY 9A (West St.) into the Battery Tunnel (I-478). Although both examples involve Interstates, they are really left turns in a city street context, not freeway ramps.

Eastbound Duke Street (VA-236) has a flyover into Landmark Mall in Alexandria. The mall itself died–Sears is the only retailer still operating there, and the former Macy's space is being used as a homeless shelter. There are plans to redevelop the site, so I'd wager the city and the developers would just as soon see Sears close.

https://goo.gl/maps/FQ6c26CNDwH2
I thought of that when I saw Thing 342's post.  Even when I used to go to Landmark back in 2001, it didn't seem like the mall was busy enough to warrant a flyover.

Landmark used to get reasonably busy back in the 1970s and early 1980s. I'm not sure what caused it to decline so dramatically. Changing demographics in the area may have been part of it. Woodies going out of business certainly didn't help, and the Lord & Taylor that replaced Woodies didn't last for all that long. But that alone wouldn't have killed the mall. Perhaps there are just enough other better alternatives around here.

One Florida location that used to exist was in Miami Beach, at 63rd St. (SR-907) and Collins Ave. (A1A).  This one made a left on to NB A1A, and had a flashing red light at the exit to discourage wrong-way traffic.  The flyover was removed in the mid-to-late 2000s, and had a low clearance.

Air Base Parkway and North Texas Street in Fairfield, CA is not a freeway interchange but two arterial streets.

Here's an oddball in Delaware that I forgot about: the connector between US-13 and DE-9 (New Castle Avenue) in the Southbridge neighborhood of Wilmington. https://www.google.com/maps/@39.7247802,-75.5460565,305m/data=!3m1!1e3

We seem to have a few different definitions of "flyover" here; did the OP intend one in particular?

Or just a partial trumpet interchange.

It is unusual and unneeded...must've been part of another grand plan that never came to be.

I don't know if I would say that such is unneeded here.  If one zooms out, there's another similar but small type ramp linking the two roads just north of the railroad tracks.  The two roads north of those ramps become one-way streets.

I wonder if that's not an "opportunity" ramp, for lack of a better term.  That is, since a bridge over the railroad needed to be built anyway, why not add a flyover/under while we're at it?
There's one like this in Lanham, MD  https://goo.gl/maps/LCrM1LvuKX92

There used to be a setup like this in NJ at the northern end of the SR-33/US-130 multiplex.  Some time after the track was abandoned, the bridge was demolished, and the half-interchange was replaced with a signalized intersection.   https://www.historicaerials.com/location/40.25759443734952/-74.55034732818604/1947/17

I'm thinking yes. It's an odd thing: it's a flyover with a separate ramp & signal so you can do to Olive Garden.

But this loop ramp takes you from US-13 SB to DE-9.  If I'm on US-13 SB, the only thing preventing me from turning left onto D Street and going to DE-9 that way is a no left turn sign.

My guess for why it was built is that there used to be a subsidized housing complex on the road that the ramp forms.
