I'm guessing he was referring to an at-grade right turn, not a triple freeway exit.
Does one lane being a shared straight and right turn along with 2 right turn only lanes count?
https://goo.gl/maps/7S5gc4mSoRPYikTFA
Probably quite a few off-ramps.
This is a three-lane right turn from Southbound I-5 to S 320 St in Federal Way, WA: https://goo.gl/maps/uwR5s8VbgxYAR3yf7

Shouldn't the wrong-way arrows be placed just after the start of the exit ramp?
You mean those vertical arrows where the white Mercedes sedan is? I don't see any reason for those to be there at all, but they seem to be the norm in that part of Florida (not necessarily statewide). To my eye, they contradict the right-turn-only arrows. But when I use that exit I know where I'm going anyway and I tend to ignore the signs and pavement markings. (The fastest way to our relatives' house in that area is to go west on Sheridan because it has so many fewer traffic lights than Pines Boulevard does.)
I thought there were more in the Las Vegas area, but most of the ones I thought existed are double right turns.
But there's still a few:
- US 95 southbound/Summerlin Pkwy eastbound exit to Rainbow Blvd (SR 595) south (https://goo.gl/maps/4R2hpUJhV4di5CrV7)
- US 95 southbound exit to Martin L King Blvd south (https://goo.gl/maps/YMaKaFnmtEyqZsTY8)
- Tropicana Ave eastbound to Paradise Road southbound (https://goo.gl/maps/PbZZsQCGKdDkVAcL6) (main entry to McCarran Airport)
- I-15 southbound exit to Tropicana Ave west (https://goo.gl/maps/1GTpQoTGoQDdgPo89) — While not currently a triple right, I'm 95% certain it used to be (given the striped off wide left shoulder and the presence of three overhead right turn signals), but the oldest Street View imagery from 2009 still shows only double right.
The exit from NB I-225 to CO 83 (https://www.google.com/maps/@39.6572489,-104.8445868,3a,22.3y,67.37h,93.79t/data=!3m6!1e1!3m4!1swO9uKFCTbL6Ymt3dvbpw_g!2e0!7i16384!8i8192) in the Denver area has a signalized triple-right turn.
I forgot if we've had a thread on this before, or if their existences have been noted in the Triple Left threads.
2 of note:
Atlantic City, NJ: https://goo.gl/maps/PmAJKVzagmKZi9Gr9 . At the light, there's 3 separate lanes for right turns.
Philly, PA: https://goo.gl/maps/bte2fwFfwoPNRMQz6 . Go back in time and you'll see this was formerly a quadruple right turn, but they took a thru lane out in favor of a bicycle lane. https://goo.gl/maps/G5pw9vZewH77P52P7

Wow, a triple left AND right!
- I-270 WB to US 23 ramp
- I-465 WB to Keystone Pkwy ramp
Both of them have a double left turn and triple right turn.
I-64 West off ramp to Northampton Blvd (US-13) (https://www.google.com/maps/@36.8745916,-76.1962515,3a,75y,347.08h,83.09t/data=!3m6!1e1!3m4!1sSFLYJoqdguSmm6BVkFSpEg!2e0!7i16384!8i8192!5m1!1e1) in Norfolk, VA.
I-285 outer loop (Southbound on western segment) ramp at Exit 20, US 41/ Cobb Parkway. This one actually has a quadruple right turn from the ramp, with 3 lanes turning right onto US 41 and the rightmost lane being separated so that it makes the right onto US 41 and then the next right onto Windy Ridge Pkwy Circle 75 Pkwy. However, the left-most right turn lane from the ramp is directed to turn left at the next intersection onto Spring Rd, so US 41 traffic past that point only gets 2 right turn lanes.
I-285 inner loop (Northbound) at the same exit, also has a triple right turn.
https://goo.gl/maps/m7Vj7EbLvdUzqVpf6
There are probably a few more in metro Atlanta that I can't remember right now.
Edit: Corrected street name
The intersection of Edmondson Av and Franklin St. US 40 turns right at this intersection to head to downtown Baltimore. Whether it is a triple right turn or not actually depends on the time of day as you can see by the blankout sign lit up (barely).

No it does not! A semi stopped at the stop-bar would easily block the crosswalk (and the trailer of the semi would likely block the pedestrian signal head so the pedestrian wouldn't even see the "walk" indication).

That is a quite massive Michigan Left (or whatever the thing is where it's like a Michigan Left without a thru direction) situation going on. I wonder if traffic will move through it well.

It gets to that point where if you have signals on the Michigan lefts, maybe it's really not that worthwhile. Not to mention motorists needing to know which lane to be in prior to making their first right, making a tight u-turn to avoid those making a wider u-turn, then needing to make another right.
Based on this, it appears someone who wants to go straight across needs to be in the left-most right turn lane, then the right-most u-turn lane, then the right lane to simply get across the intersection.
Why does Florida have such massive intersections? I don't think I've seen that anywhere else, at least not to that degree.

I-465 WB exit at Keystone has a triple right.
Philadelphia has a quad right turn (https://goo.gl/maps/XFD6MouJyzyKJotX9) on the ramp carrying I-676 from the Vine Street Expressway to the Ben Franklin Bridge. (Yes, you read that correctly.) It's definitely cheating a bit, though, like the proposed one in Fort Myers, since the right turn is the only allowed movement here.
There used to be another similar all-traffic quad right turn in Center City on Market Street where it hit Center Square (https://goo.gl/maps/pGdL7s8AZmKnMFRMA), though this was recently reduced to three lanes to make room for a bike lane, as seen in the latest Street View.
I'm unaware of any other quad turn lanes in Pennsylvania–left or right–or any other triple right turns besides Market Street.

Do you mean the Ben Franklin Bridge?
I mentioned the one in Trooper PA that was a signalized sweeping movement from an off-ramp. There is also a quasi right turn with three lanes (loop ramp) at PA 581 and US 15 near Harrisburg.
Then there is this mess off I-76 at City Ave, where you have two off ramps join together to make a right turn onto City Ave. Not only that, but you have a lot of jockeying for the next signal, where many EB cars want to turn left to access Fairmount Park roads to bypass I-76, and other cars want to turn right to access office buildings.

Huh, not only did I miss that upthread, but I forgot that they even added that. I guess it is technically a triple right turn, as are the US 15 and US 1 examples you mentioned, though the latter two are definitely in the same "kinda cheating" category as the quad right turns I mentioned in my previous post.
Two right-turn lanes and a shared straight-right-turn lane on WB Square Lake Rd at Telegraph Rd.

Note the two missing US-24 shields that are supposed to mark the southern terminus of BUS US-24, below the lane control signs.
I found one in Australia! They drive on the left, so the equivalent of a triple right is a triple left.

A northeast thing? That Aurora example is unlike anything I've ever seen. It would be more likely that you'd find something like this in Ontario (maybe the Toronto area?), given that most of the big cities in the US Northeast have old/original infrastructure that would rarely to never have the right of way for that many turning lanes (the Philadelphia examples upthread being an exception). I suspect even triple turn lanes (both left and right) are more common in the West than they are in the Northeast.
I guess I don't realize it's that rare since that's the exit I take to get home more often than not. Glad I can live by such a unique road feature. :bigass:

Triple turns are not necessarily unusual anywhere. The only other examples I knew of, of a quadruple right turn, are in New York City: one exiting northbound out of the Brooklyn—Battery Tunnel, and another at Columbus Circle. There was also a quadruple right turn in downtown Philly. So of the four I knew of, two were in Penna and the other two in NYC. And I'm sure NYC has at least one more tucked away somewhere. But I've never heard of one out west. The Aurora example seems to be the first.

I guess I was thinking more of triple left and right turns with my comments. Quadruples seem to be rare across the board, while triples are easier to find, but still not necessarily common.
When I think of a triple turn the first thing that comes to mind is a new, modern interchange in the West or Southwest, similar to the Aurora example. There are certainly a few around in the Northeast, but most interchanges either don't have the ROW or didn't need it when they were constructed and have never been upgraded, so I couldn't list more than a few offhand.
Here's an example from my city. https://www.google.com/maps/@56.0101131,92.8718397,3a,75y,0.41h,85.55t/data=!3m6!1e1!3m4!1sZPLxCWM38Xh_GV-OQbVv3g!2e0!7i13312!8i6656?hl=en-US
