It popped into my head recently that there are very few intersections with a full set of turn lanes. When I say this, I mean there is at least one designated left and one designated right turn lane on every approach, for a minimum total of eight turn lanes. Protected right turns can count, as long as they do have a designated lane on the approach.
I wonder how high we can get as far as total number of designated turn lanes at an intersection. If all turns had two designated lanes, that would be 16. I have doubts that there are any with 16 though :meh:
The first one that came to my mind is Van Dorn Street and Franconia Road (https://www.google.com/maps/@38.7840919,-77.1362125,303m/data=!3m1!1e3) here in Fairfax County. Total of eleven turn-only lanes and one optional right-turn lane (going anticlockwise around the intersection here): SB Van Dorn has two left-only and two right-only, EB Franconia has two left-only and one right-only, NB Van Dorn has one left-only and one right-only, and WB Franconia has one left-only and one right-only as well as an optional right-turn lane.

Wow, that started with a bang! Right turn lanes don't seem to be that common around here (though we still have a good few).
Very common in Delaware. Just a few examples...

So, just to be clear, I went down to latest posts and added the twin sets and general L/R turn lane sets, so there may be an error with that number, but I am human. But, if you would like to correct the count with what you have in mind you may.
Well, that didn't take a whole lot of searching for Wichita. I literally checked fewer than ten intersections and came up with two.

You're missing the point. The OP is looking for an intersection with a "full set of turn lanes". He then defines that as being "a minimum total of eight turn lanes." So...
intersection = set = minimum total of eight turn lanesIf you're counting lanes, or if you're counting twin sets, or whatever, then you're not counting intersections.
Unless I've miscounted, this post brings the total to
9 intersections = 9 sets.

That is not only correct, but well stated :thumbsup:
I won't prevent anyone from making a different definition of "set" (if you want to count each intersection as four, or eight, or whatever, that's fine), but I was considering a complete intersection to be a set for the purposes of this thread, hence my confusion.

Yep, there are quite a few (though less than I originally thought now that I think about it harder), and the number is quickly growing (eg. Cole and Fairview, and Eagle and Fairview now qualify, even though you wouldn't see it in Google Maps satellite view). In addition, most of them have dual left turn lanes on at least two, if not all legs.
Here's one example though, Overland and Cole. Bonus points for being literally on top of 11 lanes of freeway. https://www.google.com/maps/@43.5902057,-116.2742477,219m/data=!3m1!1e3

Especially when you consider it's in the middle of nowhere. Interestingly enough, it's completely balanced at street level: https://goo.gl/maps/gCwdZuKSWeq with two left turn towers, two right turn towers, and one straight through signal head per direction.

Well, that's great, but it's not a single intersection :pan:
Many metro areas in Florida can boast of two lefts + one right per direction of travel at a four-way intersection. Pick almost any two SRs in South Florida, Tampa Bay, Orlando, and Jacksonville, and you'll find it. But the triple-lefts and dual/triple-rights...those are rarer.

Nearby, US 441/FL 7 and Forrest Hill Boulevard (FL 882) has an impressive array. Southbound FL 7 has 3 left-only and 2 right-only turn lanes to go with 4 through lanes. It's 3L/1R for northbound US 441/FL 7. Eastbound CR 882 has 3L/2R. Westbound FL 882 has 2L/1R.

I know that intersection quite well, as you may not be surprised to hear.
Funny, I just started a thread about street grids (or the lack thereof), and I had this intersection in mind when complaining about the lack of good street grids in the mid and outer suburbs (Fairfax, Loudoun, etc), warranting intersections such as these, as opposed to where I am in Arlington/Alexandria, where they are scarcely seen due in part to our street grids.
They’re not that rare on major arterials in Salt Lake. Here’s one in Salt Lake City, at 400 South and 700 East (https://www.google.com/maps/@40.7607046,-111.871057,185m/data=!3m1!1e3). All four approaches have 3 through lanes, 2 left turn lanes, and a right turn lane for a total of 12 turn lanes and 12 through lanes.
There are a ton of intersections that come really close, but often one of the approaches has a shared through/right turn lane.

Well, that's great, but it's not a single intersection :pan:
I was about to disagree, considering the frontage road as a single thoroughfare with a wide median. But then I determined, if there is storage capacity under the overpass, then it certainly can't be counted as a single intersection.

The thing I find most interesting at that intersection is that if you're northbound on Six Mile Cypress going to turn right onto eastbound Daniels, there's a part-time "No Turn on Red" that's indicated by a light-up sign that comes on when traffic coming the other direction has a green arrow. I can't say I've seen that anywhere else that I recall. In the Street View image linked below, the light-up sign is in the black box hanging between the two signals displaying green arrows across the way from the Google car's viewpoint (roughly above the minivan's hood).
