Largest cities without a 3-di

[Life in Paradise]

What is the largest city to previously have a 3di but no longer have one?

Any bigger than Evansville, IN?

Fayetteville, AR comes to mind. Used to be I-540 before it was I-49.

Chattanooga, by a nose; depending on how you count I-124.

Does 124 serve the greater Chattanooga area?

Unless things have changed, I-124 is just now unsigned, but still exists on the rolls.

Here's a fun one if someone wants to try to figure this out?

Based on population at the time the National Interstate and Defense Highways Act was passed, what is the largest city that does not have a 3di today?

Doubt I'll get 1956 population, but 1950 CITY population it's:
59) New Haven
73) Austin
74) Chattanooga*
75) Erie
79) Evansville
90) South Bend
98) Corpus Christi
99) Phoenix

*Unsigned interstates currently

I ignored the New Jersey cities that were suburbs of NYC and Philly as well as Gary due to Chicago. Also ignored Sacramento due to I-505.

58) Johnstown, PA
65) Fresno
71) New Haven
78) Huntington
79) Chattanooga*
80) Lancaster
86) Spokane
87) Erie

Also found 1950 metro area population:
57) Harrisburg

I-283

87) Erie

Doesn't have one today, but used to have I-179, which is current I-79 north of I-90. No idea why that part needed a 3di instead as I-79 in the first place.

Also, fun to see which metro areas which are now not all that relatively populous were in the top 100 back then. Some select ones fun to see:

14) Buffalo
18) Providence
30) Youngstown
37) Dayton
38) Allentown
44) Wilkes-Barre
48) Wheeling
55) Charleston, WV
58) Johnstown, PA
60) Utica
68) Flint
75) Duluth
78) Huntington

Yep, my bad. I even zoomed in on GMaps because I couldn't remember if it had one or not. Edited.

The largest city in Oklahoma with no 3di in its city limits is Norman. If you ignore that, since it's part of the OKC metropolitan area, the next-bigger one is Lawton (90,381).
