Longest Time You Stayed on One Highway on a Given Trip

[Techknow]

I don't know if you've done the whole thing, but the entire northern alignment of CA-1 is beautiful. You turned around at the Point Arena Lighthouse, but if you went a little farther north, you'd have gotten to the Mendocino Bluffs and the Glass Beach area of Fort Bragg. Farther north from there, there is a dramatic inland swing once CA-1 hits the King Range and enters the Redwood Curtain. It's maybe my favorite drive in all of California, and I go out of my way to drive it anytime I can.

If you're ever in the area again, I'd suggest spending some time around Mendocino/Ft. Bragg. Lots of beautiful coastal trails and short day hikes.

I been through a fair bit of CA 1, besides that segment I traveled on it from Mill Valley to the town at Big Sur before the Pfeiffer Canyon Bridge over the past 5 years. I'd love to drive thru Big Sur and rest of the Shoreline Highway portion. Too much for a day trip though, maybe one day when I am able to spare 2 or 3 days for such a trip, then I'll have a new record for staying on Highway 1 (wherever there's an inn/hotel of course)!

About 660 miles on Interstate 40 from Greensboro to Memphis.

Mine would be I-90 from O'Hare (where we merged on) to Rapid City SD on a road trip. 900 miles on the dot.

And Bruce gets bumped out of the golf score position...

I thought CPZ drove the entire length of I-70 from the vicinity of Baltimore  to Cove Fort on his trip. Where does the 50-mile discrepancy between those two scores come from?

One of them rounded 2150 up to the nearest hundred, based on the sign in "Baltimore".

[hbelkins]

Googling "how long is I-70" gives you a big result of 2,151 miles.

[hotdogPi]

Googling "how long is I-70" gives you a big result of 2,151 miles.

Googling "how long is us 20" gives you a result that we found to be incorrect in a different thread.

[SkyPesos]

Googling "how long is I-70" gives you a big result of 2,151 miles.

Yea, the sign in "Baltimore" rounded up to the hundreds place.

[Hobart]

This is small beans compared to a lot of people, but I-80 from I-76 in Nebraska to the exit in Tinley Park, Illinois I get off at is about 803 miles according to Google Maps.

Now, it would be I-94 from Medora, North Dakota to Madison, Wisconsin, which is about 825 miles, but my dad and I took I-694 because it appeared to be slightly shorter than taking I-94 through downtown Minneapolis and St. Paul.

[hbelkins]

Googling "how long is I-70" gives you a big result of 2,151 miles.

Googling "how long is us 20" gives you a result that we found to be incorrect in a different thread.

But there is no disputed gap in I-70 the way there is in US 20.

Didn't we find that the "common knowledge" answer included all alternate routes and business routes added on to the total and not just the mainline?

[index]

Probably I-95 from its junction with I-26 to its junction with I-4. This was for a trip to Florida, circa 2009. Either that or I-95 from its junction with I-85 to Manhattan. I think the latter is longer but I can't check right now.

[Techknow]

I don't know if you've done the whole thing, but the entire northern alignment of CA-1 is beautiful. You turned around at the Point Arena Lighthouse, but if you went a little farther north, you'd have gotten to the Mendocino Bluffs and the Glass Beach area of Fort Bragg. Farther north from there, there is a dramatic inland swing once CA-1 hits the King Range and enters the Redwood Curtain. It's maybe my favorite drive in all of California, and I go out of my way to drive it anytime I can.

If you're ever in the area again, I'd suggest spending some time around Mendocino/Ft. Bragg. Lots of beautiful coastal trails and short day hikes.

I been through a fair bit of CA 1, besides that segment I traveled on it from Mill Valley to the town at Big Sur before the Pfeiffer Canyon Bridge over the past 5 years. I'd love to drive thru Big Sur and rest of the Shoreline Highway portion. Too much for a day trip though, maybe one day when I am able to spare 2 or 3 days for such a trip, then I'll have a new record for staying on Highway 1 (wherever there's an inn/hotel of course)!

Bumping this to update my answer and maybe others can contribute their answer to this question!

Well guess what today I really did do this, although it was a day trip that took me 9.5 hours instead of a 2-3 day trip. So I must change my answer!

Now I have driven on CA 1 from CA 156 all the way to CA 46 in one period of time, which is about 119 miles according to Google Maps directions. It took me almost 4 hours to drive this stretch, including stopping for 20-30 minutes to soak in a bunch of views. But that's not my longest distance on a given trip, I returned home by taking US 101 from CA 46 to CA 85, which is 148 miles. I could have kept going to San Francisco but instead took CA 85 and I-280 b/c it's shorter Still in last place, I'll have to plan longer road trips!

[lakewobegon]

I just saw this thread and wanted to add my mediocre totals to the list.

758 miles I-94 from jct. I-90 Billings, MT to west of St. Joseph's, MN (CSAH 75) (St. Cloud-Spokane trip)
659 miles I-80 (jct I-81 Hazelton, PA to Tri-State Tollway parting of I-80/I-294) (moving sister from Stoneham, MA to St. Cloud, MN)

424 (423.8) miles SK/AB TCH 1  east of Moose Jaw, SK to eastern Calgary/Stoney Trail, AB (several trips to Canmore, AB, once to Vancouver, but took Coquihalla Hwy in BC)
203 miles MN 23 (jct MN 15) St. Cloud to I-90 Beaver Creek Township MN  (current detour doesn't allow me to follow route) (many work trips St. Cloud to Sioux Falls)

Took Bypass US 52 around Jamestown, ND or would be able to have Portal, ND/Canadian border to west of St. Joseph's MN (although unmarked in concurrency in MN) (Also during St. Cloud to Canmore trips)
Still, very mediocre.

[jlam]

I just boosted my total to 740 miles along US 287 from Aurora to Ft. Worth in my early June trip to New Braunfels.

[Love2drive]

As a driver, approximately 665 miles from Greensboro NC to Memphis on Interstate 40.

As a passenger., 760 miles from St Louis to Limon, Co on Interstate 70

[Flint1979]

I-75 from Perrysburg, Ohio to Macon, Georgia and back  Done that many times btw.

[KCRoadFan]

I-70 from the I-55 interchange in Troy, IL (east of St. Louis) to the I-270 interchange in Frederick, MD (northwest of Washington) - 758 miles.

[roadman65]

I've driven I-75 from Detroit to Wildwood, FL ( where Florida's Turnpike splits fro it),.

Driven I-95 from I-4 to I-295;in DE too many times.

Drove I-10 from I-75 to NOLA in one drive.

I've done the whole length of the original I-49 in LA twice.

US 1 from Titusville, FL to Fort Lee, NJ putting up with all the continuous stop lights from Northern VA to just past Baltimore and all the other metro areas like Columbia, SC that has bad timed signals along Two Notch Road, and from Longwood Gardens to the PA Turnpike has signals way too frequent.

I've done I-90 in SD between I-190 in Rapid City to I-29 in Sioux Falls, SD.
I-29 from Sioux Falls, SD to Kansas City.

I-70 from Cove Fort to Denver, Limon, CO to Kansas City, Kanas City to Vandalia, IL, and from New Stanton, PA to Columbus, OH.

I-5 from I+505 to I-205 near Portland.

US 101 from Crescent City, CA to Ukiah, CA and from Ukiah to SF.

I-24 from its EasternTerminus to its western end.

I-57 from I-24 to US 24 in IL.

US 31 from I-465 to its northern terminus.

[Bickendan]

Let's see... US 14 from Shell Canyon, WY to Rochester, MN 935 mi
I-94 from MN 610 to Billings, MT 818 mi
US 395 from Kennewick, WA to Reno, NV 620 mi
CA 1 from Leggit to Pismo 445 mi
I-5 from CA 170 to I-205 in Tualatin, OR 932 mi
I-10 Slidel, LA to Beaumont, CA 1850 mi
Put me down for that one.

[pderocco]

My longest trips on a single road were back in the 1990s, before we had GPS, and I didn't keep such detailed trip logs that I can be certain I didn't skip a few miles getting off to eat or sleep and getting back on, or even that I didn't bypass some city on a 3di. These trips would be:

• I-70 from its western end to Frederick, MD, 2083 miles
• I-10 between Baton Rouge, LA and Los Angeles CA, both directions on two different trips, 1815 miles
• I-5 from Lake Oswego, OR to Pacoima (Los Angeles), CA, 925 miles

All distances are from Google.

I've done lots of cross-country trips, but unless I'm in a hurry, I usually avoid staying on the same boring interstate. The longest non-interstate runs I've done were:

• US-6 from Bishop, CA to Santaquin, UT, 506 miles
• US-6 from UT-96 near the Scofield Reservoir to Central City Pkwy in Evergreen, CO, 411 miles

That last one was actually a little longer, because wherever US-6 was signed along I-70, but there was an old alignment available, I took the old alignment.
