Cities Served by Only One or Two 2di's

[Brandon]

Indiana (Top 10 largest cities)

Indianapolis: 4 (I-65, I-69, I-70, I-74)
Fort Wayne: 1 (I-69)
Evansville: 1 (I-69)
Carmel: 0
South Bend: 2 (I-80, I-90)
Fishers: 1 (I-69)
Bloomington: 1 (I-69)
Hammond: 3 (I-80, I-90, I-94)
Gary: 3 (I-80, I-90, I-94)
Lafayette: 1 (I-65)

Gary is served by four: 65, 80, 90, and 94.  65 ends there.

[US 89]

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:

Salt Lake City (204k): 2 - 15, 80
West Valley City (134k): 0
West Jordan (117k): 0
Provo (116k): 1 - 15

Continue a little further down the list, and we have:

Orem (99k): 1 - 15
Sandy (95k): 1 - 15
St George (93k): 1 - 15
Ogden (87k): 2 - 15, 84
Layton (79k): 1 - 15
South Jordan (79k): 0
Lehi (73k): 1 - 15
Millcreek (61k): 0
Taylorsville (59k): 0
Herriman (56k): 0
Logan (52k): 0

[Hot Rod Hootenanny]

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)

[SkyPesos]

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.)

0) 2
1) 27
2) 32
3) 28
4) 9
5) 1
8) 1   

So 61 of the top 100 have two or less.

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

Pretty sure Detroit has three 2-di's:  I-75, I-94 and I-96.

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.

[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
3) Chicago - 9
4) Dallas - 6

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.

59) Bridgeport - 2 (I-84, I-95(

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.

Good catch, but that's the issue with metro areas in New England:  They include entire counties.

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.

Yes, I totally missed I-96.  Not sure why.

Yeah I see now that I quoted you instead of GaryV.

[Flint1979]

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.

[AcE_Wolf_287]

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

[michravera]

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.

[michravera]

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)

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.
