Longest Time You Stayed on One Highway on a Given Trip

[amroad17]

While driving for my dispatch company out of Cincinnati in 2006, I had a delivery in San Francisco.  I travelled on I-80 from Davenport, IA to San Francisco--1950 miles.

148, I-95 from MD 295 (along the Beltway) to I-85.

I haven't done too many trips where I stayed on one highway but, Interstate 20 from DFW to Atlanta has got to be up there for me (768 miles). I've also been on Interstate 40 from OKC to Asheville NC (950 miles) earlier this year.

Breaking it down by route type:

Some new updates for my breakdown:

Interstate: I-10 between Slidell, LA and Lake City, FL, 445 mi
US Route: US 59 between downtown Houston and Texarkana, 298 mi
State Route: TX 71 between Columbus and Austin, 87.2 mi TX 35 between Angleton and Corpus Christi, 174 mi
FM/Secondary Route: FM 2004 between Lake Jackson and Dickinson, 41 mi
County Road: CR 288 between Angleton, TX and Clute, TX, 7.5 mi CR 25 between West Columbia, TX and Brazos Bend, TX, 15.9 mi

Obviously allowing for getting off at exits to get gas/eat/sleep:

1215 miles: I-40 from Barstow, CA to Oklahoma City, OK
1067 miles: I-70 from Indianapolis, IN to Denver, CO
1034 miles: I-80 from Cheyenne, WY to South Bend, IN
884 miles: I-90 from Rapid City, SD to Schaumburg, IL
741 miles: I-94 from Freeport, MN to the western end
620 miles: I-65 from Clarksville, IN to Mobile, AL

My longest non-interstate are:

270 miles: US 41 from Saint John, IN to Henderson, KY
268 miles: US 30 from Bourbon, IN to Canton, OH

So my longest of other types:

State highway: 136 miles, M-37, Traverse City to Grand Rapids
County roads: 32 miles, CR 36/New Rd/CR 300 S, Elkhart/St. Joseph/LaPorte counties
City street: 24 miles, Western Ave (Chicago), 119th St to Howard Ave

[JayhawkCO]

I thought I'd do mine by route type too:

Interstate: 1174 miles. I-80 from US101 to I-180 in Cheyenne
Trans-Canada Highway: 976 miles. TCH16 from TCH1 to AB93
U.S. Highway: 546 miles. US36 from I-225 to I-29
Provincial Highway: 435 miles. SK16 from end to end
Multi-State State Highway: 371 miles. IL/MO110 from I-80 to I-35/435
State Highway: 329 miles. IL110 from end to end
Multi-County County Road: 33 miles. MN Scott/Dakota CR 42 from Scott CR17 to US61
County Road: 26 miles. MN Dakota CR42 from Scott County Line to US61

[7/8]

My longest is I-80 from the I-90/I-94 junction in Lake Station, IN to I-76 in Big Springs, NE (1343 km or 835 mi).

I'll join the "other types" trend too.

Interstate: see above
Trans-Canada Highway: ON 11 from ON 628 in Red Rock to ON 655 west of Cochrane (596 km / 370 miles)
Provincial Highway: Same as above
US Highway: US 2 from Ironwood, MI to Grand Forks, ND (616 km / 383 miles)
State Highway: M-28 from M-123 in Newburry to US 2 in Wakefield (375 km / 233 miles)
County/Regional/City Road (multiple counties with one number): Full length of Simcoe CR 45 & Kawartha Lake CR 45 in Ontario (53 km / 33 miles)
County/Regional/City Road (single county): Simcoe CR 124 in Ontario from ON 10/89 to somewhere near Collingwood (49-51 km / 30-32 miles)

Trans-Canada Highway: 976 miles. TCH16 from TCH1 to AB93
U.S. Highway: 546 miles. US36 from I-225 to I-29

Multi-State State Highway: 371 miles. IL/MO110 from I-80 to I-35/435
State Highway: 329 miles. IL110 from end to end
Multi-County County Road: 33 miles. MN Scott/Dakota CR 42 from Scott CR17 to US61
County Road: 26 miles. MN Dakota CR42 from Scott County Line to US61

Also, I thought it would be interesting to see how long I've been on a single system, i.e. only Interstates, US Highways, etc.. Concurrencies are irrelevant. (i.e, if I'm trying to count interstates, it doesn't matter if there is a U.S. Highway concurrent. If I'm trying to count U.S. routes, it doesn't matter if I'm on an interstate also.)

Interstates Only - 1,815 miles. From Eagan, MN on I-35E->I-35->I-40->I-25->I-10->I-19 to Rio Rico, AZ
Trans-Canada Highways Only - 1,033 miles. From MB42 in Winnipeg, MB on TCH1->TCH16 to Jasper, AB
U.S. Highways Only - 783 miles. From Flagstaff, AZ on US180->US89->US160->US85/87->US6 to Brush, CO
State Highways Only - 371 miles. From Hampton Township, IL on IL110->MO110 to Claycomo, MO

My longest trip staying on interstates only was 2095 miles, from Long Beach CA on I-710->I-10->I-15->I-40->I-35->I-44->I-70->I-465 to Carmel, IN

It's hard to get work done when I see these kinds of posts .

Interstates: 1833 km / 1139 miles (Battle Creek, MI to Denver, CO: I-194 > I-80 > I-76 at Pena Blvd)
US Routes: If the unsigned US routes through Yellowstone count, then it's 735 km / 457 miles (Idaho Falls, ID to Casper, WY: US 20 > US 191 > US 26 > Bus. US 20). Otherwise it's my US 2 answer from before.
State Highways: 528 km / 328 miles (North of St. Ignace, MI to Wakefield: M-123 (full length) > M-28)
TCH: 1190 km / 739 miles (Sault Ste. Marie, ON to Red Rock then to near Cochrane: ON 17 > ON 11)
Provincial Highways: 1558 km / 968 miles (Sault Ste. Marie, ON to Red Rock to Timmins to Sudbury: ON 17 > ON 11 > ON 655 > ON 101 > ON 144)

You people should start another thread.

Thought about it, but it's all related. And a good portion of the information is a carryover.

That one I would really have to think about.  Most of my long trips are 99% interstate, and even the short ones I will use as much interstate as possible, so the system will get interrupted if using non-interstates.  I prefer the better quality roads with no traffic lights when I am dozing on the 18th hour of driving.    It has only be exacerbated since owning a 33' motorhome that is frankly built to be on an interstate and not some windy back road (except the entrance to a state or national park).
