What section of numbered highway have you been on the most?

[Roadgeekteen]

For me, an easy one. Some portion of MA 135 in Needham.

MN 101 between Elk River and Rogers, probably

[Max Rockatansky]

AZ 51, AZ 101, US 27, CA 41, CA 198, FL 436, FL 15 and would US 1 would be the most common for me.  I'm not sure which one is the actual winner. 

[webny99]

Easy answer. One of two sections of NY 286; one was the blowout winner through the early years of my life, but now it's become surprisingly competitive. Not disclosing the start and endpoints for obvious reasons. 

[SkyPesos]

Same answer as my US highway one (US 22 in the Montgomery area), except this time, it includes OH 3 as they're in a concurrency.

[NWI_Irish96]

The IN 106/IN 331 concurrency in Bremen, IN.

[I-55]

IN-3 in Allen County

[TheStranger]

US 101 (Bayshore Freeway and Central Freeway) between San Mateo and SF and Route 82/El Camino Real in San Mateo County, followed closely by I-280 and I-380.

[Big John]

WI 54 in Green Bay.

[bing101]

For me, an easy one. Some portion of MA 135 in Needham.

CA-37, CA-51 and CA-29 are the sections I been on the most.

[LM117]

US-117 in NC in Wayne and Wilson counties.

[JayhawkCO]

Either K-10 or CO83.  Probably the former for total mileage and the latter for amount of times.

Probably CA 82 (El Camino Real) in Mountain View, Palo Alto, and Menlo Park.  Main commercial street and street busses run along.

[ctkatz]

the kentucky state highways by my house (unnamed as to not doxx myself) and us 31E and 150 in addition to 264, 64, 65, and 71.

[US 89]

Easy - US 89 near Salt Lake City. Hence my username.

[jp the roadgeek]

Definitely some portion of CT 10 near I-84.

[thspfc]

WI-19 in northern Dane County.
