What section of US Highway have you been on the most?

[SEWIGuy]

For me, US-12 between Fort Atkinson, WI and Whitewater.  I have driven that stretch literally thousands of times.  (Which would make WI-89 the state highway I have driven the most since they duplex.)

[Rothman]

Eesh.  I commuted on US 53 from Superior to Duluth for over a year.

But, I also ended up on US 5 in western MA a whole lot living there for over a decade and then US 9 and US 9W in the Capital District.

Probably US 9W.

[Roadgeekteen]

The portion of US 1 that's concurrent with I-95 between Dedham and Canton.

[TheHighwayMan3561]

Probably the section of US 10 in Elk River, MN.

[SkyPesos]

A section of US 22 in the Montgomery area (NE of Cincinnati).

[hotdogPi]

I-95/US 3 east of the Burlington Mall exit.

[bing101]

US-50 Sacramento because I used to work and go to school in Sacramento for 4 years.

[webny99]

There are legitimately no US routes in my area. Probably the following sections of US 20, in roughly this order:

(1) NY 444 to US 20A (eastern terminus)
(2) NY 332 to NY 364
(3) Lake St (Geneva) to NY 96A

[Max Rockatansky]

Either US 27 in Lansing, MI or US 1 from Cudjoe Key to Key West.

[GaryV]

Probably US 12 in Sturgis, when visiting my wife's family before her folks passed away.  Although US 23 would be a close contender, probably the winner in recent times.

[NWI_Irish96]

US 6 in Marshall County, IN, between IN 106 and Plymouth-Goshen Trail.

[I-55]

US-30 between Fort Wayne and Columbia City, IN

[Big John]

US 41 (prior to I-41 designation) Green Bay to Menasha.

[Flint1979]

US-23 between Saginaw and Flint. Which happens to be the same answer as my interstate highway because US-23 runs concurrent with I-75 in that stretch.

For a US highway that isn't concurrent with any other highway it'd probably be US-10 between Midland and Bay City.

[fillup420]

close call between US 74 (grew up in Charlotte) and US 70 (currently work and live along it).

[LM117]

It's a toss-up. I grew up in NC in Wayne County, so it's a tie between US-117 and US-70 in the whole county, as well as the part of US-117 in Wilson County.

[kkt]

US 101 on the San Francisco peninsula.

[pianocello]

I use a stretch of US 441 in Gainesville on my daily commute, but it's going to take years for that to beat out any of the US Routes in my hometown.

[Avalanchez71]

US 31 (SR 6)part (SR 7) part.  US 412 (SR 99)

[bwana39]

US271 between Talco and Paris (TX)

[zzcarp]

It has to be US 20 in the Wakeman, Ohio area-specifically from Green Road to Wakeman proper and on to Western Reserve High School near Collins. Besides trips with my parents, I took that route every day on the school bus (or later driving myself) from Kindergarten to High School graduation. And I took that route often when working after college graduation until I moved to Colorado at age 28.

[JCinSummerfield]

US-23 between Dundee, MI & Toledo, OH.

[JayhawkCO]

From the interstate thread...

It's probably close to a tie for me between:
I-435 (KS) between US69 and Metcalf
I-35 (KS) between Lamar and Southwest Boulevard
I-25 (CO) between Evans and University

Chris

Because they all duplex:
US50 (KS) between US69 and Metcalf
US69 (KS) between Lamar and Roe
US85/US87 (CO) between Evans and University

Chris

[gr8daynegb]

Prior to 2001:
US 12 between Wisconsin Dells to Madison

2001-2011:
US 41 between Green Bay and Oshkosh

2011- present
US 141 from Coleman to Green Bay(with 41 from Abrams to Green bay)

[ET21]

Hmmm I've been on a ton of sections throughout my lifetime but I'd say these are probably the most frequent since I started paying attention

US-12: Suburbs of Chicago
US-20: Suburbs of Chicago, Rockford IL to Dubuque IA
US-30: Oswego IL to Waterman IL
US-34: Chicago suburbs
US-41: Lake Shore Drive, north side of Chicago into Skokie
US-45: Chicago suburbs
US-51: Rochelle IL to Madison WI
