I-85: Atlanta to Greensboro
I'd say Durham over Greensboro... the connection to Raleigh-Durham from the I-85 South corridor is a pretty large one.

Don't forget the segment has to be at least 20 miles in length.

I-95: I would buy Richmond to NYC before I bought DC to Boston. Compared to the Richmond to DC segment, I-95 is unimportant between New Haven and Providence.

It gets a lot more interesting if we say you can't "skip over" a large metropolitan area - you must end the segment and restart at each metro area you hit.
That leaves five major segments: Richmond to DC, DC to Baltimore, Baltimore to Wilmington, DE, Trenton to NYC, and NYC to New Haven, CT. You could make a case for any one of those five. I'd lean towards #4 (NJTP to GWB).

Good topic.
I-39: Tri-concurrency from Madison to Portage, but the Jane Addams tollway part is close
I-94: Downtown Chicago to downtown Milwaukee
I-43: The whole thing through Milwaukee
Western I-76: Brighton to I-70

We can play that game with I-17 and I-19, too, can't we?

Depends on how one defines "important."  In the case of I-17 and I-19, I define it as a segment that will screw up the entire length of the interstate if it is closed for some reason, and there is no alternative route.

I-17:  New River Rd. to AZ 69 at Cordes Junction.  There is no nearby alternative to this route other than the old, mostly unpaved Black Canyon Hwy (old AZ 69). If this segment of 17 is closed by a wreck or a wildfire (like what happened yesterday), anyone who's on that section is royally screwed.  Between New River and metro Phoenix, and north of 69 to Flagstaff, there are alternative routes.

I-19:  Green Valley to Nogales.  Same situation, with no viable alternative route nearby.  The only other route between Nogales and Tucson is AZ 82 to AZ 90 to I-10 at Benson.  AZ 83 is there, between AZ 82 and I-10 at Vail, but I wouldn't drive a semi on it.

Clinched, minus I-93 (I'm missing a few miles and my file is incorrect)

Traveled, plus US 13, 44, and 50, and several state routes

I will be in Burlington VT for the eclipse.

I-41 doesn't go to Chicago. :pan:

Unless they mean state line to Milwaukee.

That's interesting. The only one that I disagree with outright, is I-71, which should be Cleveland to Columbus.

"Most traveled" is certainly one measure of importance, but I'm not sure if it's the best measure.
It needs to be some combination of high traffic volumes, lack of alternate routes, and strategic (ie, used for a wide variety of trips).

There's something to be said for the route's local importance- specifically whether or not it connects metropolitan areas of local and/or regional importance.
Main Line Interstates clinched:  2, 4, 5, 8, 10, 11, 12, 14, 16, 17, 19, 20, 24, 25, 26, 27, 29, 30, 37, 39, 43, 44, 45, 55, 57, 59, 65, 68, 71, 72, 74 (IA-IL-IN-OH), 76 (OH-PA-NJ), 78, 80, 82, 86 (ID), 88 (IL)

I-69: Indianapolis to Lansing via Fort Wayne.
Connects two state capitals and IN's two largest cities.

BTW, the "new" portions of I-69 south of Indy SHOULD HAVE (IMHO) been designated as I-63 to Memphis, and other route numbers south of there. But the POLITICIANS saw otherwise, designating the designation in legislation for the entire corridor south of Indy to México.

Similarly, the E-W portion in MI through Flint should have been called I-98 or something else with an even number. Then, I-69 should have been continued north from Lansing to terminate at I-75, eliminating the ridiculous renumbering of old US 27 to US 127.

What is this data based on? I guess I have a hard time believing that I-5 is more crucial through SeaTac than in Southern California.

It's the Travel Mapping site. More people on that website have been on that particular segment in Washington than in Southern California.

I understand Barstow to Vegas...Vegas to St George tho? That much O/D traffic to St George, or a decent percentage of traffic continuing on the handful of Utah State Routes out of St George?

And within this area, the least important part of 95 is north of Philly to the NJ Turnpike, because of the NJ Turnpike.

... and in fact, that part of I-95 had zero importance until recently, as it did not exist.  :-P

95 existed...just not on the route that exists now. Someone driving between the PA Turnpike and points North on 95 never missed 95, and someone headed from Philly to the Trenton/Princeton area never missed 95.  If your points of travel were between Philly and points south, it was very important and useful.

Quote from: J3ebrules on August 02, 2019, 11:39:56 PM

Honestly, if 95 were still incomplete, I would not have argued that the Jersey stretch is important. But now that it is the main route to NY from Philly, it works... in theory.

In reality; I still would cross into Jersey to 295 (for the higher speed limit, to avoid NE Philly traffic, and to shunpike a bit), then jump onto 195 to get onto the turnpike. I'm assuming that's what most area natives do, 95 completion notwithstanding?

Going North, most natives would just take 95, because the natives are used to the traffic. Going South, I would imagine many would take 95 to Philly as well, especially if they have EZ Pass, because the cost is going to be about the same. I doubt many are taking 295 any significant difference to save about $1 in tolls.

I-95, Richmond to Boston

I-95 doesn't go to Boston

Oh come on.
I mean yeah it technically does not enter city limits but it serves the area.

any sane person would use a different road.....once they fought it it should have been moved out of the area lol

I-70: New Stanton to Breezewood.  :sombrero: :bigass: :popcorn:
<ducks>

That could be true, actually. To the east is the massive conurbation along and near I-95, from Washington DC to the southern half of the New York metropolitan area. To the west is a loosely-formed conurbation along and near I-90, from Cleveland to Milwaukee, and several more decent-sized metropolitan areas along and near I-70, from Columbus to St. Louis. When I-70 runs concurrently with the Pennsylvania Turnpike, it becomes a conduit for all long-distance traffic between those conurbations, beginning on the eastern exurban fringe of Pittsburgh, and passing through some of the most difficult terrain east of the Mississippi River. It's exactly why the Allegheny Mountain Tunnel replacement project is so important, because the entire segment of I-70 concurrent with the Turnpike needs to be widened to six lanes.

I'd bet a lot of that traffic is exiting on UT 9 to go to Zion National Park.
