Largest city without a U.S. highway (besides Honolulu or Anchorage)

[Takumi]

Long Beach had US 6.

[NE2]

Long Beach had US 6 and US 91 (as well as US 101 Alt).

The largest city in Oklahoma appears to be Bethany, pop. 19,607, which is wholly encompassed by OKC. The next-largest is Mustang (17,190), another OKC suburb.

The two towns in Arkansas I found were Centerton (pop. 9,515, a late-growing suburb of NWA) and Heber Springs (pop. 7,165, a county seat in the middle of a popular recreation area).

[US 41]

Bloomington, IN is the largest city in Indiana I can think of that doesn't have a US hghway.

[mapman1071]

and US 89 through Tucson.

And US 95 currently goes through Yuma.

US 89 Has been Decertified South Of Flagstaff
And I Forgot US 95 Passed Thru Yuma

In the northeast: Waterbury, New Britain, Middletown, and Norwich, CT; Lawrence, MA; Newport, RI; all of LI (Hempstead, Islip,); Vineland, NJ; Rockville/Gaithersburg, MD.

Hempstead and Islip are towns, not cities.  The only cities on Long Island are Glen Cove and Long Beach.  The latter doesn't even have a state route passing through it, much less a US route or interstate, although the proposed but unbuilt I-878 would have passed through it.

Hempstead is also a village, the state's most populous. Indeed, the town is also the state's most populous of those. Both entities have more residents than many true cities (the latter, all but one city, in fact).

Yeah, Bloomington beats out Fishers by just under 4,000 people.  Of course those are 2010 Census figures and the way Fishers is growing it's probably bigger now.

If you're talking about "now", then San Diego, CA (population 1,307,402) is probably the largest city without a U.S. highway, and has been since the 1960s (1964?) when U.S. Highway 80 was decommissioned and U.S. 101 and 395 were shortened.  Other present-day California candidates include Long Beach (462,257), and Oakland (390,724). 

CalTrans did an unbelievably effective job in eradicating U.S. highways from their system during that realignment.

For Colorado, I think it would be Arvada (101,000). Although I-70 passes through the south side of that city, it doesn't have U.S. 40 running concurrent with it at that point. For Minnesota, I'm looking at Eagan (66,000). Picky people might point out that the early routing of U.S. 65 pre-1934 (now MN-3 and MN-149) ran through what is now Eagan, but it wasn't incorporated as a city at that time. There was, however, an Eagan Township that became the city by the 1970s.

Obviously.

Ha!

For Utah:

Tooele--While US-40 once came close via UT-138, US-40, as far as I can tell, never actually went through Tooele itself.

Also, Hurricane.

Nope.

The subject asked for a U.S. Highway. I think it's hard to dispute.

Mount Pleasant, MI is served by two freeways, but not either of them are interstates.

In the UP of MI you have Escanaba that is a large city by the region it sits in.  The UP has less than 10 percent of Michigan's total population, from what I have read once, so in the Lower Peninsula Escanaba would not be a major anything, especially around Detroit it would be the smallest of the suburbs.

I guess it depends on the area, what is considered large as far as this topic is concerned as it was implied by some already.

MP has a US highway, and so does Escanaba.

I thought this was the other thread about interstates. Duh!  I am so used to seeing that thread, its in my mind too much.

Then pretty much all of Nassau County, NY fits this and Port Jefferson and Riverhead in Eastern LI as well.

Keene, NH, although it has NH 9 and NH 12 that are a regional network of roads in the New England States, though not US routes, but are NE's way of saying they do not need US routes, we have the same type of network.

Elmira, NY, Jamestown, NY,  Rochester, NY(especially since US 15 no longer goes there and US 104 decommissioned),and even Utica, NY do qualify.

I believe Vineland, NJ is one being that US 40 does not technically enter its limits, but  in fact comes close as it does pass through Malaga, a town just to the north of it on NJ 47.

It's served by exactly one freeway.

so in the Lower Peninsula Escanaba would not be a major anything, especially around Detroit it would be the smallest of the suburbs.

This isn't at all true.  There are at least 10 suburbs smaller.

Perhaps you should calm your eagerness to post (and do a modicum of research) because that isn't the first time you've erred in that regard.

If you're going to go this way, wouldn't it be Shanghai?

[agentsteel53]

and now I do wonder what the most populated city on the planet is which is not served by an interstate-quality freeway.  Karachi looks somewhat underdeveloped.

Has to be Havana or Pyongyang.

In the northeast: Waterbury, New Britain, Middletown, and Norwich, CT. 

US 6 goes north of Waterbury around Watertown. US 6 merges/leaves I-84 at Exit 38 in Farmington, a good mile or more from the New Britain city line. US 5/CT 15 [Berlin Turnpike] gets as close as bordering Berlin and Newington. Yay? Finally, I think Norwich would be closer to US 1 as opposed to US 6 or 44.

If it means anything, New Britain has about ~72,000 or so.

Havana's ring road not only exists (!) but looks to be a pretty well-done dual carriageway (!!)

it has cloverleaves, yes, but so does Boston's ring road.
