I am curious what is the longest an interstate goes at the bare minimum 4-lanes. Obviously that means it spends a long time away from major population centers that would cause the interstate to gain a lane in each direction. I have a feeling I am going to get a lot of American Southwest answers.
I-90 between La Crosse, WI and near Spokane is my guess.
There's six-lane stretches of I-90 in Sioux Falls and Rapid City.

I'd expect most of the contenders to be in the Great Plains and the intermountain West, including the northern parts. But there could be methodological issues, such as how to treat lanes gained at one interchange that are dropped at the next (e.g., the third lane in each direction on I-80 between I-180 and Lincolnway in Cheyenne, Wyoming).
In Colorado and Kansas, I-70 remains at the base four through lanes all the way from Chambers Road (Exit 283) in Denver to I-470 (Exit 355) in Topeka, a distance of 521 miles.
In Utah, Wyoming, and Nebraska, I-80 remains at the base four through lanes all the way from SR 224 in Kimball Junction, Utah (Exit 145) to milepost 394.6 in Nebraska (just west of US 77 on the outskirts of Lincoln). This is a total distance of 849 miles. However, if the added lane in Cheyenne is counted as a departure from the base four lanes, then we are left with two sections of 409 miles and 439 miles respectively.
I haven't looked at I-90 in detail, but I'd expect it to have long lengths too, running from roughly Coeur d'Alene to Rapid City, and from Rapid City to Sioux Falls, and then Sioux Falls to Austin, and maybe Austin to Onalaska. After that it gets chopped up more.

I-40 might be a contender. In California it is always 4-Lane, and still is from the Arizona state line to Flagstaff (I been on this stretch of interstate but it's been years). It becomes 6-Lane at Albuquerque, not sure before that
How long is I-81's longest continuous 4 lane stretch? That's my first thought for an east of the Mississippi contender, as everything else mentioned already are west.
I-10 between the outskirts of El Paso and San Antonio?

Not really IMO. In Sioux Falls there's a CD lane in each direction between I-229 and SD-115 (less than a mile). Same thing in Rapid City, between I-190 and Haines Ave. If you count that as a six lane stretch, it begs the question of just how long a CD lane needs to be in order to qualify as an extra lane.
I-94 from its western terminus in Billings to just past I-29 in Fargo is all two lanes at a little over 600 miles.

I don't know if I missed something but I drove I-80 through Cheyenne this past September and saw no evidence of a third lane between any of the exits there. It was four lanes between each exit there in town. So unless a lane's been added very recently I think I-80's four-lane stretch from Echo Junction to Omaha stands pretty good.
There are climbing lanes between Cheyenne and Laramie not to mention most of the stretch between Omaha and Lincoln is now six lanes, right? It's been a while since I've driven it.
Doh! I meant to say Lincoln, not Omaha. I only drove 80 west to Laramie and didn't see any climbing lanes but the eastbound side might have had them.
Isn't I-90 four lanes through the La Crosse, WI area? If so, it then continues as four lanes eastward to the I-39 'Cascade' interchange.

The potential break in four lanes falls between US 87 and Lincolnway in the westbound direction (https://www.google.com/maps/@41.1143782,-104.8593447,3a,75y,308.07h,74.71t/data=!3m6!1e1!3m4!1sUL2GFxtKz0lxFUvOVS-C2g!2e0!7i16384!8i8192) (not, it seems, the eastbound, contrary to my initial impression).

Yes, there is definitely at least one climbing lane in the eastbound direction (https://www.google.com/maps/@41.2654269,-105.469202,3a,75y,96.06h,82.6t/data=!3m6!1e1!3m4!1sCVb-S0c_vMc_76CBcJIb2A!2e0!7i16384!8i8192). And yes, I-80 is now at a basic six through lanes all the way from just west of Lincoln to the western outskirts of Omaha. In the westbound direction at least, milepost 394.6 has a pavement stub (https://www.google.com/maps/@40.8195161,-96.8033143,3a,75y,270.17h,87.82t/data=!3m7!1e1!3m5!1sioWq-uRCOyDW1uwlFxSENg!2e0!6shttps:%2F%2Fstreetviewpixels-pa.googleapis.com%2Fv1%2Fthumbnail%3Fpanoid%3DioWq-uRCOyDW1uwlFxSENg%26cb_client%3Dmaps_sv.tactile.gps%26w%3D203%26h%3D100%26yaw%3D325.35965%26pitch%3D0%26thumbfov%3D100!7i16384!8i8192) where three lanes become two.

My opinion would be that an auxiliary lane that joins at one interchange and exits at the next interchange < 3 miles away does not count as a lane, but a climbing lane does.

I don't consider them to be lanes. You can't drive in that lane for any distance of consequence.

That's a long distance to be considered a merge/weave area. I wouldn't argue with less than a mile but three miles indicates there is significant extra traffic between those two interchanges. It would certainly be true if that extra lane included a bridge over a river, swamp, or other barrier which would force local traffic to use the freeway.
I'd consider a third climbing lane on one side more than four lanes.
OTOH, I wouldn't count C/D lanes at all unless they were fairly lengthy, like a couple miles.

So you would count this section of I-43 (https://www.google.com/maps/@43.7548553,-87.7656218,1540m/data=!3m1!1e3) as more than four lanes?
I guess I didn't even think about these possibilities when creating this thread. I will amend with this: lanes added specifically for a safety reason will not count, because usually they are added for that specific geography in that specific direction of travel. Example being a climbing lane. Since the opposite direction is a downhill, the third lane is not needed. There are sometimes a climbing lane is stripped differently than the other two lanes to alert drivers that this is not a usual lane and will end as soon as we get to the pass. Lanes created between an entrance ramp and an exit ramp that are closely spaced, and their main purpose is to ease weaving also don't count because the geography in the opposite direction is usually not the same so that stretch of freeway is technically 5 lanes. Now there can be some debate on length of a weave lane making it count or not count toward a widened freeway.
Mainly I am looking for Interstates that are rural for long stretches and even when they go through a small town, retain their 4 lane properties for the most part. (see I-10 in Lordsburg, NM).
A few nominees for the Northeast:
I-89: Entire length
I-91: From north of Exit 15 in Holyoke, MA to the Canadian Border (and up to the eastern A-10/A-55 split near Sherbrooke)
I-95: I-295 in Scarborough to the Canadian border (and all of NB 95).

I think it would be interesting to see what answers we get with
and without counting different types of break in four basic through lanes: climbing lanes, weaving lanes, and lanes gained and dropped between consecutive interchanges.
Personally, I think the last-listed should be counted as breaks because they do not lend themselves to the same operational characteristics as four through lanes with no gains or drops at exits, and are usually found in urban areas with a significant traffic burden (which does not always track with population, as in the case of Rapid City and Onalaska).

I agree. Maybe subcategories. One that doesn't count climbing lanes are weaving lanes at intersections as breaks in rural/basic 4-lane continuity and one that does count that as to get an accurate count of the longest stretch of purely rural freeway.

Similar to the mentions about I-90 Rapid City and Sioux Falls, there is a six lane section between exits 155 and 156 in Mandan, ND, helping traffic go between Mandan and unsigned I-194 (Bismarck Expressway). Since there is debate about how to count something like that I just wanted to make sure that fact is known.

An auxiliary lane between two closely spaced interchanges is hardly a "six lane stretch" .
If you put a line 90° to the centerline and it intersects 4 sets of white stripes, it means it has 6 lanes. Any other definition is boring. "How long between any two 6-lane stretches? Oh, but not that one. Not that one either." Snoooooore.

So, in your mind, the question devolves to "what's the longest stretch of interstate between two exits?"
I think for purposes of having a different piece of trivia, this question could be more precisely described as "longest stretch of interstate with only four lanes (excluding acceleration/deceleration lanes at exits, and auxiliary lanes that are/should only be marked with lane drop striping".
In other words, a perpendicular line drawn across the interstate should encounter two sets of standard lane dash stripes (assuming modern markings).
pretty sure 70 is 4-lanes through pa, but thats only ~160 miles
i would say just about most of 76 (oh-nj), but its 6 lanes between exits 67 and 75 and possibly for the entire 70 concurrency

Concurrency with I-79 got widened to 6 lanes a few years ago.
Also, the PA turnpike have various 6 lane sections here and there.

Not at all. There are plenty of places, especially outside of cities, where an on-ramp does not add or remove a lane, especially if you don't count accel/decel lanes. But "auxiliary lane" is such a nebulous concept that by disqualifying them, you instantly turn the question from "here's a fun piece of trivia" to "let's rules-lawyer every single possible answer to the question so it stops being fun". Hell, there's a post upthread where someone thinks an auxiliary lane can be 3 miles long. That's ridiculous–at one point Oklahoma had
left-side lanes that started and ended faster than that.

However, if you go by the stripe-counting standard you proposed, that would cause acceleration/deceleration lanes (which are supposed to be separated with lane-drop stripes) to "count".
Using lane-drop striping would provide an objective way to exclude exit/entrance/auxiliary lanes....except for some DOTs not being on top of implementing that part of the MUTCD.

In which case the objective standard should be places where the MUTCD says lane-drop stripes SHOULD be used. I personally don't know what that is, however...

Quote from: Scott5114 on May 08, 2022, 03:19:22 AMIf you put a line 90° to the centerline and it intersects 4 sets of white stripes, it means it has 6 lanes.
So, in your mind, the question devolves to "what's the longest stretch of interstate between two exits?"
Not at all.
However, if you go by the stripe-counting standard you proposed, that would cause acceleration/deceleration lanes (which are supposed to be separated with lane-drop stripes) to "count".
Oh FFS, everyone knew what he meant. The pedants really make this group difficult to enjoy at times.
No, not everyone knew what he meant.
Nah, I am pretty sure the vast majority did.
As evidenced by the fact that . . . no one except you came to his defense?
No, I just have faith that the dear contributors of this message board aren't idiots.

We're all idiots. Anyone who says differently is selling something.
I-85 is 4 lanes from I believe around US1 in northern NC and its northern terminus, and also 4 lanes from said interchange to the Durham county limits IIRC
I-75 is an unusual one for this topic. It is 2 lanes (except aux lanes and climbing lanes) from Bay City up to the Soo, approx 230 miles. But, only northbound. Southbound you pick up a third lane from Grayling (the sb Biz 75 entrance) to the I-75/US-127 split. You could say this is an auxiliary lane. However, this is a long distance, plus their is an exit in-between, 4-mile Road. So, southbound I-75 has about a 5 mile gap, but not northbound.
