The 20 lane road in Naypyidaw, Myanmar. Technically not a freeway, otherwise ON-401 like many others.

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!
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, 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,
Quote
The 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.

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)

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:

https://www.google.com/maps/@40.7142824,-74.1392861,114m/data=!3m1!1e3

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 widest freeway I've been on is I-80 through Omaha. At its widest, 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.
