Title: Widest freeway you've been on
Post by: webny99 on April 02, 2019, 08:33:51 AM
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.

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.

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.

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.

Just south of the northern 75/85 split (https://www.google.com/maps/@33.7879744,-84.3913495,187m/data=!3m1!1e3) it reaches 16 lanes (7+2 HOV southbound, 6+1 HOV northbound). That's not counting any of the ramps right there, and also not counting the 4-ish no-longer-used "lanes" in the median.

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.

From 1995 to around 2007-08, the Lantana Toll Plaza (https://www.google.com/maps/@26.5630437,-80.1734856,221m/data=!3m1!1e3) on the southbound side of Florida's Turnpike was 12 lanes wide, back in the days before the concrete barriers separating the dedicated SunPass lanes. 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!

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.

Does that include just I-395's lanes, or includes the separate VA 27 freeway which runs through the Mixing Bowl?

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?

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.

I was going to say this 18 lane section of the 401 in Mississauga, (https://maps.app.goo.gl/ecWGm) but this one trumps it a fair bit! I-75/85 in Atlanta is also high on my list.

From 1995 to around 2007-08, the Lantana Toll Plaza (https://www.google.com/maps/@26.5630437,-80.1734856,221m/data=!3m1!1e3) on the southbound side of Florida's Turnpike was 12 lanes wide, back in the days before the concrete barriers separating the dedicated SunPass lanes. 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!

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!

Mine too.

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.

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.

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?

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.

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 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).

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.

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.

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.

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.

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.
