50K+ urban areas not connected to the Interstate system by four-lane highways

[NE2]

I tried to figure out the 41 areas mentioned and came up with the following:
*Albany, GA (ca. 1984 by US 82)
*Altoona, PA (1989 by US 220? or was US 219-22 first?)
*Athens, GA (ca. 1989 by US 78)
*Bremerton, WA (ca. 1983? by SR 16)
*Brownsville, TX (ca. 1988 by US 77)
*Bryan-College Station, TX (when?)
*Chico, CA (never)
*Dubuque, IA-IL (ca. 1988 by US 20)
*Enid, OK (ca. 1990 by US 64)
*Fayetteville-Springdale, AR (I-540 designated 1983)
*Goldsboro, NC (ca. 1992? by US 70)
*Harlingen-San Benito, TX (ca. 1988 by US 77)
*Houma, LA (ca. 1982? by US 90-LA 24)
*Jacksonville, NC (recently?)
*McAllen-Pharr-Edinburg, TX (ca. 1988 by US 77)
*Muncie, IN (when?)
*Newark, OH (recently?)
*Panama City, FL (ca. 1986 by US 231)
*Pittsfield, MA (never)
*Poughkeepsie, NY (ca. 1990?? by US 9)
*Round Lake Beach, IL (when??)
*San Angelo, TX (ca. 2003 by US 87)
*Seaside-Monterey, CA (never)
*State College, PA (I-99 designated 1995)
*Vineland-Millville, NJ (1989 by NJ 55)
*Wausau, WI (ca. 1987 by US 51)
*Williamsport, PA (I-180 designated 1983)
*Wilmington, NC (I-40 designated 1984?)
*Yuba City, CA (recently?)

That's only 29, so AHTD must have been counting them differently.

*Round Lake Beach, IL (when??)

Round Lake Beach is a part of Chicagoland, close to Waukegan, so I don't know what metric they were using.

Bend is the one that comes immediately to mind. 150,000 people in the metro area, 80,000 in the city, and two lane roads connecting it to everywhere else in the state.

I think Lompoc, CA qualifies too, but those are the only other ones in California.

SR 1-135 appears to be four lanes all the way to Santa Maria and US 101. Not the most direct connection, but it's there.

What about in places where the road turns in an intersection.  In Lompoc's case, where CA-1 turns in front of Vandenberg's main gate, only one lane makes the northbound right turn:

Think a bit. How many places are connected to the Interstate system by one-lane ramps from four-lane roads?
