What is it, and how many lanes does it have?
For me, I think it's this segment of ON 401 near Toronto (https://www.google.com/maps/@43.7111706,-79.5441669,3a,75y,302.42h,86.59t/data=!3m7!1e1!3m5!1sPXY3WcksGuCmxY4aC2KBGw!2e0!6s%2F%2Fgeo2.ggpht.com%2Fcbk%3Fpanoid%3DPXY3WcksGuCmxY4aC2KBGw%26output%3Dthumbnail%26cb_client%3Dmaps_sv.tactile.gps%26thumb%3D2%26w%3D203%26h%3D100%26yaw%3D108.35532%26pitch%3D0%26thumbfov%3D100!7i16384!8i8192), which has about 15 lanes, depending on how you count.
I-75/85 in Atlanta.
The Turnpike section mentioned below is wider, and I have been on it.

Now you've got me thinking. I
may have been on that stretch. I'll have to take a Street View tour and attempt to identify if/when.
I-5, just south of the I-405 split in Orange County CA, has 26 lanes divided into six roadways (HOV, regular, truck). I've driven it multiple times.
I drive through this regularly: I-95 immediately south of the Beltway in Springfield, Virginia, has a total of 24 or 25 lanes across seven carriageways/flyovers. It's a rare situation where the southbound exit roadway* has more lanes (six, at its widest) than any of the carriageways for thru traffic.
*I say "exit roadway" rather than "C/D road" because it doesn't provide access to the southbound thru lanes–it's only for exiting traffic. Thus, the "C" part of "C/D" doesn't really fit and "D road" sounds to me like a very low-importance European road.
The Katy Freeway (I-10).

Right around here (https://www.google.com/maps/@38.7855396,-77.1786784,281m/data=!3m1!1e3), I think I can get that count up to as high as 27 briefly. Regardless of the exact number, I'm betting this is my winner since I haven't been on the part of I-5 mentioned above.

Yeah, I've never been on I-5 at all, so I was pretty confident in my answer. The Golden Glades in Florida may be the biggest tangle of ramps I've been through, but I'm reasonably sure that no single road passing through there has 25+ lanes.

Yep - Same here. Although, at which point does each carriageway take on a different number? Is it considered 95 across all 27 lanes, or is there a mix of 95, 395 and 495. At that point, does that skew the definition of the widest freeway, when it's really 3 different freeways?

That's mine as well. I was on it last summer. The first time I was on it, 1969, I think it was 8 lanes even then.
I-465 just north of I-70 on the east side of Indy. I have no clue how many lanes it is.
Widest I've driven was West Main Street in Rapid City- six lanes, double yellow lines for the median.
(On another note, does anyone have that Wide Lanes video?)
Unless I'm missing somewhere, the Downtown Connector in Atlanta (75/85) maxes out at 14, which ties this section of I-15/80 in Salt Lake City (https://www.google.com/maps/@40.7496881,-111.9097984,163m/data=!3m1!1e3).
If we're allowed to count C/D lanes, then my winner becomes this part of I-15/80 just to the south (https://www.google.com/maps/@40.7340189,-111.9049171,163m/data=!3m1!1e3), which features 18 lanes spread across 4 carriageways.

As with several others above, this is likely the widest for me as well.
As far as the widest freeway
without separate carriageways going the same direction, it has to be the short I-405/CA 22 concurrency near Long Beach at 16 lanes (2 HOV, 4 mainline, and 2 exit only lanes each direction).

Just to make it clear, "Beltway" was referring to I-395 passing the Pentagon, which is the original and real "Mixing Bowl," and not to the Springfield Interchange (which is sometimes erroneously referred to using that name by local media types). I cited the Springfield Interchange thinking it was the widest I've travelled, but Beltway said the Pentagon area has more lanes (which I didn't know), so I then said the Pentagon area would be the widest for me as I drive through that area quite frequently.
I think it would be the Dan Ryan for me as well, unless there's any freeway in the DFW metroplex wider than it. I don't think there is.

Thanks for the clarification. I've been through both several times. The Mixing Bowl feels like more lanes than I-395 near the Pentagon, but both are huge and confusing to those unfamiliar with the area. I'm new to So Cal so I'm sure I'll hit that I-5 mess in Orange County soon enough. I've already handled the challenge of navigating through the I-5/I-10/US 101/CA 60 cluster.

The NJ Turnpike/I-95 section mentioned earlier is possibly the widest I've driven. I can't think of anywhere else I've been which beats that.

I'm pretty sure I-635 is wider than the Dan Ryan at its widest now. I think the Dan Ryan maxes out at 16 (3+4+4+3, plus the occasional ramp/auxiliary lane on each side), and I see a 17-lane section of I-635 under Montfort Dr.
The widest I've been on, by the way, is I-395 by the Pentagon.
In NJ it is the NJ Turnpike between 11 and 14 being at 14 lanes and 4 roadways.
However, talking about bridges its the Alfred Driscoll on the Garden State Parkway now with its 14 lanes as well. Have that on my youtube page back in 2012 I filmed it.

Actually, 15 lanes. 7 Southbound; 8 Northbound split into two, 4 lane roadways.
Oh did not realize they put 8 on that one. I have to rewatch my video, but that is even more impressive at 15 lanes wide.

That's probably the single widest slab I've driven on which wasn't an abandoned airstrip.
Hmmm...looks like the NJTP toll plaza for the George Washington Bridge is at least 15 lanes in one direction!

Same for me, used to be part of regular work trips. Driven the Katy Freeway numerous times as well which I believe is also 26 lanes.
Looks like Wikipedia somehow calls the Katy Freeway the widest in the world.
Wikipedia has a lot of wrong facts if you look hard. Like US 202 being longer than its parent. I posted that here on the forum when I was a rookie and everyone here read me the riot act on that one.
I think the writer meant to say longer than the segment of US 2 that it branches from, but many here thought at the time it still was inaccurate to say that on there.

I don't consider there to be a separate VA-27 freeway inside the complex, as its connections use the C-D roadways of I-395.

AKA "El Toro Y". I drive this all the time since I only live 3 miles away from it. I want to say that at widest spot is just north of Lake Forest Rd. it is west to east 3 lanes (south truck bypass lanes/Bake Pkwy/Lake Forest Rd exit) +3 lanes (end of I-405 south) +3 lanes (I-5 south) +1 lane (I-5 South HOV) +1 lane (I-405 HOV south flyover merge) +1 lane (I-405 HOV north flyover) +1 lane (I-5 North HOV) +3 lanes (I-5 North) +3 lanes (I-405 North (3rd lane appears on right during split)) +2 lanes (Truck lanes for I-405) +2 lanes (Truck lanes for I-5 North). I get 23 total lanes, so I am missing three somewhere
There is also the 2 lane Alton Pkwy on ramp that goes underneath the Truck Bypass before entering I-5 South. Also an auxiliary lane from from El Toro North on ramp to Lake Forest Rd North off ramp, but that is further south. Are those the other three?
As far as I can tell, they're all 12 lanes and a 3-way tie:
- NJ Turnpike south of Exit 11/Garden State Parkway (northernmost I've driven on it is Exit 11)
- I-84 in East Hartford/Manchester CT between Exits 55-59, which is also 12 lanes (including HOV)
- I-95 north of Baltimore MD between Exits 62-67 (including express lanes)

Been on NJTP by I-95, 401 in Toronto, I-395 and I-95 south of Washington, but I don't think I've driven by the Pentagon example.
The NJ Turnpike's Exit 11, connecting with the GS Parkway, is 25 lanes wide with no express lanes, making it one of the largest, if not the largest, single slab plazas in the US. There's 26 toll booths though, as the right most lane in the GSV below is a thru lane to a offsetting 2 booth plaza (or whatever you would call that).
https://goo.gl/maps/QgrZE5q6isB2
Other wide plazas (over 20 lanes) but aren't single slab include Baltimore's I-95 Fort McHenry Tunnel at 22 lanes wide including the 2 way-too-slow express lanes. The NJ Turnpike's Interchange 1 was designed for 25 lanes without Express EZ Pass, but was modified to 23 lanes to include the express lanes, and has a large median between directions.
Since wide toll plazas are being mentioned here, I immediately think of the Bocaue toll plaza on the North Luzon Expressway (NLEX) - 25 booths southbound, 13 northbound.
https://www.google.com/maps/place/NLEX+Bocaue+Toll+Barrier/@14.8023616,120.9408336,645m/data=!3m2!1e3!4b1!4m5!3m4!1s0x3397ad9ffa8e971d:0x8bb60b77ee98b0a8!8m2!3d14.8023616!4d120.9423903
Somehow it was so congested here this past Sunday that it took 30 minutes to get through the plaza southbound!
I can update mine, I think, if we include convoluted C-D road setups: I-264 east of I-64 in Norfolk VA (https://www.google.com/maps/@36.845858,-76.1903559,189m/data=!3m1!1e3), 14 lanes.

My old Kia broke down on that stretch of freeway back in '04; I was in the leftmost GP lane -- and a fan blade broke off and sliced through the radiator; by the time I got all the way off to the right an onto an offramp, the engine had seized. Apparently that problem was common to some '02 Kia models; they subsequently did a recall -- and replaced my engine free. Still, trying to negotiate 12 lanes of traffic with a steaming car was a bit unnerving!

Don't tell me things like that... The plastic circle around the fan in my car came apart last year, causing the fan blade tips to rattle against a piece of it as they turned. I repaired it with super glue. I also had the radiator replaced the same year, completely unrelated.
Widest freeway I've been on is the NJ Turnpike's 12 lane dual-dual section. And, at some point during my travels, I've driven in each of the sections (southbound general, southbound cars only, northbound cars only, northbound general).
I'll go with the Dan Ryan too, if only because it's in my hometown.
Katy Fwy, but I don't think that really counts since feeders are goosing the numbers. The "26 lane" segments have at least 10 feeder lanes.
The 18-lane segment of the NJ Turnpike has more mainlanes and is far more visually impressive.

I think it would be the Dan Ryan for me as well, unless there's any freeway in the DFW metroplex wider than it. I don't think there is.
I'm pretty sure I-635 is wider than the Dan Ryan at its widest now. I think the Dan Ryan maxes out at 16 (3+4+4+3, plus the occasional ramp/auxiliary lane on each side), and I see a 17-lane section of I-635 under Montfort Dr.
The widest I've been on, by the way, is I-395 by the Pentagon.
I've never been on that section of I-635, so it is the Dan Ryan.
The Santa Ana Freeway I-5 in Orange County, CA that section used to be a 6 lane freeway until they widen the freeway back in the late 1990's to 2000's to have 10-12 lanes.
The Dan Ryan for me. Honorable mention to I-75 through Atlanta
I think I've driven pretty well all of the wide freeways in North America now to be honest.
US 59 (Southwest Freeway) in Houston. I've been on the really wide section of the Katy, also - but before the widening was complete (I think it was 10-12 lanes at the time.)
The widest freeway I've been on is a section of I-35 in southern Oklahoma. It has 4 lanes and a median more than 700 feet wide.
I'd have to say the New Jersey Turnpike, with the dual car/truck lane roadways.

I have wondered what is the purpose of a median that is more than about 150 feet wide. That is wide enough in a treed area to completely separate the roadways and make them invisible to each other, eliminating headlight glare from the opposing roadway. I know of numbers of places where for long sections that the median is 400 feet to 500 feet wide or even wider. Why?

I-5, just south of the I-405 split in Orange County CA, has 26 lanes divided into six roadways (HOV, regular, truck). I've driven it multiple times.
This would be the record-holder for me as well (I'll be driving through it again today), but I want to give an honorable mention to CA-91 through Corona, which gets to 18-lanes wide at some points (22 lanes if you count the ramps).

Using that seemingly valid interpretation of the OP, I'm going with the Deadman's Pass portion of western I-84, which seems to be about a mile and a half wide at one point, and has 5 total lanes.

Under this interpretation, I believe mine would be I-24 southeast of Monteagle, TN – 6 lanes total, but with the carriageways separated by as much as ~1.6 miles.
the 11 lane I-405 in Los Angeles
I was amazed by this road, especially 4 lanes each way was the widest I've seen before, and that was in a tunnel
I-75 between Windy Hill and Delk in Atlanta (just north of I-285) has 8 lanes north and 7 lanes south. That would be it for me, and I drive it regularly since I live off the Delk exit.

I didn't say it was a bad thing.
I-95 in Northern Virginia. 8 lanes with a reversible 3 lane toll. Never been anywhere else. I've stayed on the east coast.
Probably been on a 12 lane somewhere.
I recently drove on the GSP and the Driscoll Bridge, which is 15 lanes. The Viesser/Edison Bridge sits just east of it and is 6 lanes wide. Which means there's 21 lanes of bridge crossing the Raritan River!
TX-121 between the DFW airport and the split with TX-114 in Grapevine is my new longest. Very impressive stretch of freeway.
It would be the Garden State Parkway across the Raritan River for me, followed by the New Jersey Turnpike and I-95 in South Florida.
For me, ON 401
Going by the FHWA list (https://www.fhwa.dot.gov/policyinformation/tables/01.pdf), my winner is I-5 in Downtown Seattle, which it counts as 13 lanes.
However, there are sections in downtown that are 14 lanes wide if you count the ramps and express lanes, such as immediately north of the Mercer Street interchange.
Probably the Dulles Access/Toll road. +/- 12 lanes.

The 401 in Toronto.
The widest that I've been a passenger in a car on: Atlanta Downtown Connector
The widest that I've personally driven a car on: I-77 just north of Uptown Charlotte, with 12 lanes in total
Based on what others in the thread have claimed for lane counts of certain freeways, my answer would be the 27-lane section of I-395 in VA.
The MTR faq, which could be out of date, mentions several freeways of at least 14 lanes; the ones that I have been on are:
I-75 north of I-285 in Georgia (15 lanes until 2018, 17 lanes since then)
New Jersey Turnpike dual-dual section
George Washington Bridge
I-10 in the Phoenix area
I-5 in California between I-210 and route 14

The Katy Freeway (I-10).
SAMSUNG-SM-G930A
Picked up ON 401 this weekend (the big section by Pearson), so another wide one under my belt (along with GSP and NJTP...).
For roads that only have two carriageways, this section (https://www.google.com/maps/@40.4974709,-74.3009864,3a,40.9y,355.42h,84.22t/data=!3m6!1e1!3m4!1s4bbth33PeIH1xDU6vQx7Pw!2e0!7i16384!8i8192!5m1!1e1) of the Garden State Parkway is hard to top (I haven't been on it myself, though).

Those are both the widest I've been on as well. I honestly was not expecting I-95 and NJTP to be as busy as it was when I drove through, though that was on Thanksgiving Sunday 2019, and that may have added to it.
The 401 near Pearson is busy but not often congested.
My widest would also be Highway 401, the widest section which is right south of the Airport.
18 lanes (4-5-4-5)
https://www.google.com/maps/@43.6642971,-79.6032832,199m/data=!3m1!1e3
The widest freeway I have been on is the downtown connector in Atlanta (75/85)
I think it has like 5 lanes, and it is pretty hard to drive on.
Probably the Autopista Panamericana in Buenos Aires, Argentina. It's 18 lanes wide for several miles, with some merge and exit lanes that bring the total up to 20-22 in some areas. They also had variable speed limits dependent upon lane, which is brilliant IMHO.
After that, I'd say either the 401 in the Toronto area (with all the express and feeder lanes) or the 5 and/or 405 through the Southland. Hard to tell which spot is the very widest of those, but I've driven the entirety of both through the LA Area.

Overall, Thanksgiving Sunday is *the* busiest travel day of the year, and that holds true on the NJ Turnpike as well.

I was on the section of the Autopista Panamericana back in the mid-1990s, and I recall a short stretch having 9 lanes in one carriageway -- don't remember the direction. I was there on business, so I was payng attention to the lack of traffic on the main highway (toll road) and "colectora" (highway CD road, or similar) and the heavier traffic on the "frentista" (local frontage roads) to avoid the tolls. Wonder if the patterns are still that way, 25+ years later.
To stay on topic, my widest freeways traveled are the NJ Turnpike section north of Int. 14, Parkway over Driscoll Bridge, Dan Ryan in Chicago and the I-75/85 Downtown Connector in Atlanta.

I was on it about 10 years after you and it was as I described then. Because it's been a while, I looked at Google Maps and it appears to be about the same now as what I drove back in 2006 or so. At the time, I was impressed but not surprised as it's the only freeway to feed the wealthier northern suburban areas - and BA is known for it's wide (surface) boulevards, Avenida 9 de Julio is 14 lanes wide (7 each direction).
Katy Freeway for me. 26 lanes including feeders if I'm counting properly.
Ontario 401 and the Dan Ryan/Kennedy Expressway's in Chicago.
Used to everyday: Katy Freeway... up to 26 at times between IH 610 and Beltway 8..used to drive that everyday.
locally, i-70 where 76 peels off, i think thats 8 or 9 lanes, so hardly interesting..
when i was a kid, i've been through the parts of the njtp and garden state parkway mentioned upthread.
The 20 lane road in Naypyidaw, Myanmar. Technically not a freeway, otherwise ON-401 like many others.
The Katy Freeway in Houston.

Somehow it was so congested here this past Sunday that it took 30 minutes to get through the plaza southbound!
Yes I been to the NLEX toll plaza just outside the Manila city limits and it's as wide as the Bay Bridge Toll Plaza. This area gets called a jammed freeway during holidays.
Widest Carriageway: I-65 north of exit 90 (Briley Parkway) - 8 lanes
Widest 2 carriageway: Probably 15 lanes same spot as above
Widest overall: (depending on how we're counting this) I-65 north of KY-1065 Outer Loop (16 lanes) Otherwise its the above

What is it, and how many lanes does it have?
For me, I think it's this segment of ON 401 near Toronto (https://www.google.com/maps/@43.7111706,-79.5441669,3a,75y,302.42h,86.59t/data=!3m7!1e1!3m5!1sPXY3WcksGuCmxY4aC2KBGw!2e0!6s%2F%2Fgeo2.ggpht.com%2Fcbk%3Fpanoid%3DPXY3WcksGuCmxY4aC2KBGw%26output%3Dthumbnail%26cb_client%3Dmaps_sv.tactile.gps%26thumb%3D2%26w%3D203%26h%3D100%26yaw%3D108.35532%26pitch%3D0%26thumbfov%3D100!7i16384!8i8192), which has about 15 lanes, depending on how you count.
There is a distinction between "most number of lanes" and "consuming the widest right-of-way". I was just on CASR-237 at I-880 in San Jose last night. At that point, I-880 is about 10 different roadways. Since it's all single-stack, it's about 600 m across. I-5 and CASR-14 have a concurrency with truck bypass lanes that might come close or exceed it. The MacArthur Maze (I-80, I-580, I-880, and maybe others) might be similar. I'm sure that there are squarer configurations that would have an even longer diagonal. Also, it is common, especially in South America, to have a park in the middle of roadways and I'm sure that some service plazas give roads a large amount of right-of-way.
For a long time, the Guinness Book listed the Bay Bridge toll plaza as having the most lanes at 22. I don't know the current number of lanes there (although I've been there in the last two weeks) or what roadway might currently have more lanes.
the "widest" for me is as others have mentioned, the El Toro Y in Irvine (the 5 and the 405) and the 405/22 in seal beach. according to the wikipedia,
QuoteThe freeway's annual average daily traffic between exits 21 and 22 in Seal Beach reached 374,000 in 2008, making it the highest count in the nation
i don't know if the 405 in Seal Beach is still the busiest in the nation but i wouldn't doubt it. it's the 405 freeway because you move 4 or 5 mph.

Some areas have cash lanes.
I do believe widest 1-carrigeway is I-85 in Durham (which gets as wide as I believe 9-10 lanes and as narrow as 4) or maybe the Capital Beltway (I can't recall which is wider) and the widest 2-carrigeway is the Jersey Turnpike (which is I believe 3-4 lanes each direction each carrigeway, which amounts from 12-16 lanes north of exit 6, depending on surroundings)
9-10 lanes in one direction or total for both?
The I-10 West Freeway just outside the I-610 in Houston popularly referred to as Katy Freeway. There are eight lanes on the eastbound I-10 approaching the I-610 interchange, four exiting lanes are split into two lanes each way (610 North/610 South), while the four innermost lanes are the main-lanes that continue east to downtown.
There's about 20 lanes on the NJ Turnpike here before it splits. :bigass:

Or the GSP's 15-lane bridge over the Raritan River. There's also 6 lanes of the US-9 bridge next to it as well.

The ON 401 when I was 19.
The widest freeway I've been on is I-80 through Omaha. At its widest (https://www.google.com/maps/@41.2246567,-95.9757526,181m/data=!3m1!1e3), it's 7 lanes westbound and 6 lanes eastbound.
There are lots of places where merges and splits, or (former) toll stations widen the road. But to be considered an n-lane road, it ought to be n lanes for a significant distance, without counting short temporary lanes. I-15 south of Escondido, CA has about 13 miles of 14-lane highway, five regular lanes in each direction, plus four express lanes with a zipper barrier which is usually 2:2 but switch to 3S:1N for most of the morning. That's because it was built through comparatively empty land.
I-85 Jeff Gordon Expressway between I-485 and Bruton Smith Boulevard. 12 lanes, 6 each way.
Second place is I-77 Bill Lee Freeway between I-85 and I-277. Also 12 lanes, but that includes 2 toll lanes each way that are separated by a barrier.
