Trying not to be too exhaustive, but what major cities (population 100,000 or more) are served by just one or two 2di's?
I'll give you two examples:
I-4 is the only 2di (1di?) that goes through Orlando, FL.
I-35 and I-80 meet in Des Moines, IA.
So your thread subject said 3di and your post said 2di.
I'm gonna go by what your post said.
South Bend is served by only I-80/90
Fort Wayne is served by only I-69
Evansville is served by only I-69 and (perhaps) I-64
Aurora and Naperville are served by only I-88
Elgin is served only by I-90
Grand Rapids is served by only I-96
Ann Arbor is served by only I-94
Peoria is served only by I-74
Austin: ranked 11th in the country, only one 2di
This list is going to include almost all big western and central cities...
Salt Lake City, I-15 and I-80
Phoenix, I-10 and I-17
Tucson, I-10 and I-19
Las Vegas, I-15 and I-11 (which I guess doesn't reach Vegas city limits yet but serves the metro)
Reno, I-80
Boise, I-84
Los Angeles, I-5 and I-10
Sacramento, I-5 and I-80
San Francisco/Oakland, I-80
Portland, I-5 and I-84
Seattle, I-5 and I-90
Spokane, I-90
Fargo, I-29 and I-94
Sioux Falls, I-29 and I-90
Omaha, I-29 and I-80
Topeka, I-70
Wichita, I-35
Tulsa, I-44
Albuquerque, I-25 and I-40
Las Cruces, I-10 and I-25
El Paso, I-10
Midland, I-10
Odessa, I-10
Amarillo, I-27 and I-40
Lubbock, I-27
Abilene TX, I-20
Waco, I-35
Austin, I-35
Corpus Christi, I-37
McAllen, I-2 and I-69C
...I could go on...
Seems to me it would be better to approach this from the other way - a better topic might be "cities with more than two 2dis".
Colorado
No 2dis
Boulder
Greeley
One 2di
Aurora - I-70
Centennial - I-25
Colorado Springs - I-25
Fort Collins - I-25
Lakewood - I-70
Pueblo - I-25
Westminster - I-25
Two 2dis
Arvada - I-70 & I-76
Thornton - I-25 & I-76
Three 2dis
Denver - I-25, I-70, & I-76 (just barely on I-76)

Going by metro areas, Columbus is a notable medium-large city in the Midwest with only two 2di (I-70 and I-71), compared to many metros with a similar size with 4 (I-65/69/70/74 in Indianapolis, I-29/35/49/70 in KC, I-44/55/64/70 in St Louis, etc).

I-78 is signed thru the Holland Tunnel and barely in Manhattan
I-80 is not signed into NY, but it clearly serves NYC

I did forget about I-78, and while I don't want to get into a Baltimore type discussion, if we're doing "cities" and not "metro areas", I think we have to define what "serve" means. Otherwise, most of my Colorado cities above get one or two added to them.

I'll go with this for "served":
1) Enters the census defined metro area
2) Has the city name as a control city for multiple occurrences.
This will allow some interstates through metro areas to be counted, like I-80 for Chicago, Cleveland and NYC, and not allowing some of the less obvious ones, like I-84 for NYC.

norfolk / hampton roads area is only served by I-64 and about a million x64's. though, from what i've read here, might eventually be hit by 87?

It also have less than 1/10 the minimum population the op wanted.
How about this:
Pick a point in the mainland US. Create a circle and expand it until reaching the third 2di. What point gives you the most populous (US only) circle?

Pittsburgh as well I think, once I-70 was pulled off the Penn-Lincoln Parkway and put on the Washington-New Stanton route that was, up to that point, another I-70S.
Speaking of Pittsburgh: it also qualifies for this thread with I-76 & I-79.

Haven't tried it yet, but if you center a point at Sacramento (I-5/I-80), and go with a radius of 350 miles (roughly where it touches either I-10 in LA or I-15 in Barstow), that would include the entire Bay Area and the Central Valley population.

It depends on your interpretation. Wichita may count if you consider I-35W (now 135) to have been different from mainline 35.

In California, San Bernardino used to be served by 2 2dis (I-15 and barely I-10), then 15 became I-15E in the 1970s then turned into a 3di in 1982 as modern I-215.
Temp I-15E reached Riverside but not sure how well that was ever signed.
Oakland used to have I-5W along I-580 in the early 1960s.
Michigan's 10 largest cities:
-- Detroit, 2 2di's
-- Grand Rapids, 1
-- Warren, 0
-- Sterling Heights, 0
-- Lansing, 1 (I-69 misses city limits)
-- Ann Arbor, 1
-- Flint, 2 (barely, only because there is an isthmus of the city limits across I-75 to the airport)
-- Dearborn, 1
-- Livonia, 1
-- Troy, 1
Throw in the charter townships that are at least as populous as Troy:
-- Clinton Twp, 1
-- Canton Twp, 0
-- Macomb Twp, 0
San Jose, CA, (10th largest population) never has had a 2di. I suppose if US-101 were to turn into I-3 between San Francisco and LA, it could happen, but highly unlikely.
For California, I'm going to use urban areas over 100K (based on 2010 figures, since 2020 hasn't been released for urban areas), as I think that strikes the balance between city proper and MSA (skewed by large county size), and demonstrates the 2di has the "intent" of serving the named city, even if it doesn't enter the city limits.

Of the 20 areas not served by any 2di, 12 of them are on the sections of either CA-99 or US-101 that frequently get talked about as future interstate corridors (at least in groups like these!).
Also of those 20, only 2 are served by at least one 3di.
I think there's too many with two, would be more interesting to limit it to cities with just one.
Buffalo, NY would be among the more noteworthy cities on that list.

Pretty sure that Lansing and Flint are served by I-69 and I-75 respectfully even though they don't really enter the city limits they serve the city. Also the GM Delta Plant next to I-69 is actually in the city of Lansing.
I'm surprised nobody's mentioned any city in North Dakota along either I-29 or I-94. They are the only two 2dis in the state.
Fargo has I-29 and I-94, Grand Forks has I-29, Bismarck has I-94 and an unsigned I-194.
Elkhart and South Bend technically have two 2dis, but does it really count? I-80 and I-90 share the same four lanes of the Indiana Toll Road, and there are no other 2dis in the area.
Also, a surprising number of Florida cities only have one 2di. Orlando, Fort Myers, pretty much any city in the Panhandle. Even the big cities, like Jacksonville, Daytona Beach, and Miami, only have two 2dis (and neither of them technically run east and west in Miami).

Ok most of those are suburbs. But did I-5W actually enter San Francisco, the city limits? I thought it only went through Oakland, and used I-580 and I-505 to connect to I-5.

Yes. Most other states would have allowed Boston to annex enough land. For example, I-465 goes through Indianapolis.
Before we got the IH 69 designation, it used to really bother me that Houston, the 4th largest city in the country, only had 2-- IH 10 and IH 45 and only 1 3di- IH 610.

1950s population... Houston was much smaller, and St Louis was the 8th largest city back then.
Also note that KC and StL have two interstates that end there in opposite directions (29/49 and 44/64), so it's like they only have three through interstates. Meanwhile, Indianapolis will get their 4th through interstate when I-69 is connected in the south.
Shanghai, population 26.32 million, has zero 2dis.
Before 2018, Trenton, NJ, had one 2di serving it (I-95) (and even then, it only went partway around). Not quite 100k population, but surrounding townships make up for it.
Now it has none.

Utah has four cities with populations greater than 100k. Two of them are suburbs. Looking at city limits only (which I think is appropriate as that's where these population numbers come from), we have:

Besides Columbus (already mentioned), Dayton is served by only one 2di & Akron is served by two 2di. All the other cities in Ohio are either less than 100K in population, or have more than two 2dis (Cincy, Cleveland, Toledo)
Ohio:
Columbus (2): I-70, I-71, "I-73"
Cleveland (3): I-71, I-77, I-90 (I-80 goes through the metro area, but doesn't enter city limits)
Cincinnati (3): I-71, I-74, I-75
Toledo (3): "I-73", I-75, I-80, I-90 (city limits border the turnpike on one side)
Akron (2): I-76, I-77
Dayton (1): I-75 (I-70 goes through the metro area, but doesn't enter city limits)
EDIT: Someone beat me to this list by 2 minutes.
It seems some want to do cities; some want to do metro areas for "serve". I would imagine the vast majority of metro areas are two or less 2dis. Let's find out. (I'm sure I missed one here or there, so be kind in your corrections. I did these from memory.)

I pointed out how can you say that I-69 doesn't serve Lansing and I-75 doesn't serve Flint? It says serves the city not goes through the city.
Sorry, Flint ... I didn't say that. My comment was limited to how many 2-digit Interstates serve Detroit. GaryV would have to answer your question.

It seems some want to do cities; some want to do metro areas for "serve". I would imagine the vast majority of metro areas are two or less 2dis. Let's find out. (I'm sure I missed one here or there, so be kind in your corrections. I did these from memory.)
[snipped]
Adding a little twist here, with each 2di segment radiating out of the metro area getting one point, instead of each 2di number. So 2di passing through a metro area will get 2 points, while 2di that end in a metro area get 1 point. Also, if two interstates are concurrent when leaving a metro area, it will only count for 1 point for both together, instead of 2 points.
1) NYC - 7 (btw you forgot I-84 for the metro area count)
2) Los Angeles - 3

Both of these have I-5 if you're going by metro areas. Although 5 doesn't pass through the city centers, it does go through Fresno County and Kern County.

I-84 doesn't come within 25-30 miles of Bridgeport. It's a 30 mile trek up CT 8 to Waterbury or a 25 mile one on CT 25 (much of which is a 2 lane road) before you hit I-84.

That's not just a New England thing. That's the reason Dayton includes I-71, Riverside includes I-40, Fresno and Bakersfield contain I-5 (after it was pointed out to me), etc.

Besides Columbus (already mentioned), Dayton is served by only one 2di & Akron is served by two 2di. All the other cities in Ohio are either less than 100K in population, or have more than two 2dis (Cincy, Cleveland, Toledo)
I would have to say that I-70 serves Dayton too regardless of not entering city limits it runs between the airport (which is included in the city limits) and the rest of the city. I-71 does not serve Dayton though I think I saw someone else mention that one.

Then in that case I-84 should be included for New Haven and Springfield. It spends 22 miles in New Haven County between Southbury and Cheshire as it passes through the Waterbury area. Plus, the western lanes clip Hampden County just before the CT border.

Trying not to be too exhaustive, but what major cities (population 100,000 or more) are served by just one or two 2di's?
I'll give you two examples:
I-4 is the only 2di (1di?) that goes through Orlando, FL.
Not only does Austin, TX have a population of 960k, but its only served by ONE!! Interstate, no other 2di's and no 3di's
Lubbock, TX Pop: 250k, only 1 Interstate which actually ends here
Springfield, MO Pop: 160k only 1 2di runs through here

This list is going to include almost all big western and central cities...
Phoenix, I-10 and I-17
Las Vegas, I-15 and I-11 (which I guess doesn't reach Vegas city limits yet but serves the metro)
Reno, I-80
Los Angeles, I-5 and I-10
Sacramento, I-5 and I-80
San Francisco/Oakland, I-80
...I could go on...
Seems to me it would be better to approach this from the other way - a better topic might be "cities with more than two 2dis".
Not to mention:
Fresno
Bakersfield
San Jose
Monterey
Ventura
Santa Barbara
and about 15 more cities in California that MAY be over 100000, but are certainly over 50000.
Which have NONE. San Jose has some 3-dis. The rest have none in the generally recognized metro area. Fresno and Bakersfield have I-5 that enters their MSA, but nothing even close in the usual sense of the term. Not even close for Monterey, Ventura, and Santa Barbara.

Semi-fun fact: Downtown Ventura (County seat of Ventura County) is closer to I-5 (45 miles via CA-126 to Castaic Junction, Los Angeles County) than Downtown Fresno is to I-5 (60 miles via CA-180 and CR-J1, still in Fresno County).
Plus, the eastern suburbs of Ventura County (Simi Valley, Thousand Oaks) are within 15-20 miles of I-5 (and I-405). And since those connections are via freeways (CA-118, US-101) and Fresno's connections to I-5 are at best expressway, I would argue that Ventura is much better connected to the Interstate system than Fresno.

Both of these have I-5 if you're going by metro areas. Although 5 doesn't pass through the city centers, it does go through Fresno County and Kern County.
But I-5 doesn't enter the metro areas as usually understood. If you count counties, I believe that I-15 barely enters or barely misses LA county (and a lot closer to the "continuous built up area" than I-5 does to either Fresno or Bakersfield). In fact, I-80 probably gets closer to San Jose (and, certainly closer to the "continuous built up area") than I-5 does to Fresno.
Ventura, Santa Barbara, San Luis Obispo, Monterey, Salinas, and Santa Cruz are completely off the Interstate system. Only Ventura (and maybe Santa Barbara, but I believe that there is a break) is even within a limited access roadway of the Interstate system. You can get to all of them without stop signs from the Interstate system, but not, in all cases, by any "nearly direct route" without stoplights.

Salinas and Santa Cruz can both be reached without stoplights via partial freeway/expressway links back to the Interstates (Route 17 to I-880/I-280, US 101 to I-280/I-680)
Ventura is a direct freeway link to I-405 via US 101, so no stoplights there. Santa Barbara is a bit further west and does involve some expressway sections of 101.
Monterey I think can be done without stoplights but takes a minimum numbered roads to get back to the Interstates from there (either 1 to 17, or 1 to 156 to 101)
SLO can be reached no-stoplight via US 101, but much more distant from the Interstates (46 might be the closest way to get to one, and it is not no-stoplight all the way east between 101 and 5)

norfolk / hampton roads area is only served by I-64 and about a million x64's. though, from what i've read here, might eventually be hit by 87?
Correct, which will eventually connect Raleigh and Norfolk once complete, along with giving the Hampton Roads metro a proper freeway outlet to I-95 South.
However, likely at least two decades off any sort of substantial complete, with no major upgrades planned for the 50+ miles of non-limited-access segments remaining on US-17 planned over the next decade, with a few exceptions near Hertford and north of Elizabeth City, though who knows with those either nowadays.
Today, Hampton Roads is a metropolitan area of over 2 million people served by only one freeway gateway, I-64, connecting to the north and west. Arterial connections are required to connect south and northeast due to lack of proper freeway grade facilities.

I see some similarities between the Hampton Roads and the Bay Area freeway systems, starting from them being served by only one 2di, that is an E-W one. Also the amount of child routes of that one 2di.

I think that CASR-156 still has a stoplight on it Westbound a couple of km east of the CASR-1 junction. ... and there is definitely a break in the freeway regardless of how you try to get there from I-5 or even I-880.

It does - at Castroville Blvd.
However, I am pretty sure 17/1 is still a valid stoplight-free route to Monterey from the Interstate system - at least I can't remember any when I drove that back in 2013.

Going by metro areas, Columbus is a notable medium-large city in the Midwest with only two 2di (I-70 and I-71), compared to many metros with a similar size with 4 (I-65/69/70/74 in Indianapolis, I-29/35/49/70 in KC, I-44/55/64/70 in St Louis, etc).
Columbus still has pretty good connectivity via US-23, US-33 and Ohio 161/37/16, just not with interstates.

... not directly if you are coming from the south or east ...

norfolk / hampton roads area is only served by I-64 and about a million x64's. though, from what i've read here, might eventually be hit by 87?
Correct, which will eventually connect Raleigh and Norfolk once complete, along with giving the Hampton Roads metro a proper freeway outlet to I-95 South.
However, likely at least two decades off any sort of substantial complete, with no major upgrades planned for the 50+ miles of non-limited-access segments remaining on US-17 planned over the next decade, with a few exceptions near Hertford and north of Elizabeth City, though who knows with those either nowadays.
Today, Hampton Roads is a metropolitan area of over 2 million people served by only one freeway gateway, I-64, connecting to the north and west. Arterial connections are required to connect south and northeast due to lack of proper freeway grade facilities.
I see some similarities between the Hampton Roads and the Bay Area freeway systems, starting from them being served by only one 2di, that is an E-W one. Also the amount of child routes of that one 2di.
I agree, with I-5 bypassing the area completely and connecting via another 2di (I-80) towards the north / east.
The only benefit the Bay Area is one of those many area 3di, I-580, actually fully depart the metro and properly link the region easterly towards I-5 South.
The equivalent with Hampton Roads should be an interstate corridor along US-58 connecting with I-95 and I-85 South.

56) Fresno - 0
62) Bakersfield - 0
Both of these have I-5 if you're going by metro areas. Although 5 doesn't pass through the city centers, it does go through Fresno County and Kern County.
But I-5 doesn't enter the metro areas as usually understood. If you count counties, I believe that I-15 barely enters or barely misses LA county (and a lot closer to the "continuous built up area" than I-5 does to either Fresno or Bakersfield). In fact, I-80 probably gets closer to San Jose (and, certainly closer to the "continuous built up area") than I-5 does to Fresno.
Ventura, Santa Barbara, San Luis Obispo, Monterey, Salinas, and Santa Cruz are completely off the Interstate system. Only Ventura (and maybe Santa Barbara, but I believe that there is a break) is even within a limited access roadway of the Interstate system. You can get to all of them without stop signs from the Interstate system, but not, in all cases, by any "nearly direct route" without stoplights.
Of those cities listed...
Salinas and Santa Cruz can both be reached without stoplights via partial freeway/expressway links back to the Interstates (Route 17 to I-880/I-280, US 101 to I-280/I-680)
Ventura is a direct freeway link to I-405 via US 101, so no stoplights there. Santa Barbara is a bit further west and does involve some expressway sections of 101.
Monterey I think can be done without stoplights but takes a minimum numbered roads to get back to the Interstates from there (either 1 to 17, or 1 to 156 to 101)
SLO can be reached no-stoplight via US 101, but much more distant from the Interstates (46 might be the closest way to get to one, and it is not no-stoplight all the way east between 101 and 5)
They have eliminated the all the grade crossings on US-101 between Ventura and Santa Barbara, so it is now fully freeway from Goleta to downtown Los Angeles.

--It seems some want to do cities; some want to do metro areas for "serve". I would imagine the vast majority of metro areas are two or ---less 2dis. Let's find out. (I'm sure I missed one here or there, so be kind in your corrections. I did these from memory.)
So, out of the top 100, they have this many 2dis:
0) 2
1) 27
2) 32
3) 28
4) 9
5) 1
8) 1
So 61 of the top 100 have two or less.

Besides Columbus (already mentioned), Dayton is served by only one 2di & Akron is served by two 2di. All the other cities in Ohio are either less than 100K in population, or have more than two 2dis (Cincy, Cleveland, Toledo)
Almost got it, but 74 doesn't enter Greensboro (85 does, so it's still 3). 95 doesn't enter Raleigh (closest it gets would be Benson, where it intersects with 40), and although 70S entered Washington area in the distant past, 70 stays well to the north.

I-70 is about .55 miles north of the Dayton city limits. Close enough. But then again, the Dayton Airport is part of the city so there probably is a some territory connecting the Airport to the rest of the city that I-70 has to run through.
