Five highways you want to drive in your lifetime

[Roadgeekteen]

I-70 west of Denver
CA 1 in the Big Sur
US 50 or US 6 in Nevada
Dalton Highway
Pam American Highway
Anything else really

[Flint1979]

US-2
MN-61
Dalton Highway
US-1
US-40 (screw I-70)

[SkyPesos]

In no particular order:
BC 99 Sea to Sky Hwy
CA 1
I-70 west of Denver
Any of the Sierra or Cascades interstate highway passes
China G50 expressway

[sparker]

1.  US 97/BC 97-YK 1:Alaska Highway/AK 2.  Weed to Fairbanks in one fell swoop (I'll wait until Weed stops burning, though!)
2.  Trans-Canada from St. Johns to Victoria, again in one session.
3.  The direct all-Interstate L.A.-N.Y. run in one trip (I-10/15/40/44/55/70/76/276/95)*.
4.  Old (1950's) MSR 789, Nogales-Sweetgrass.  Done a lot of sections, but would like to do one straight shot.
5.  US 62, EB (NB?):  The weirdest, but arguably most interesting, of the few true diagonals. 

*yeah, I know getting off 76 onto 283/83/81/78's technically shorter, but Harrisburg's a PITA; and if PennDOT and PTC can't get their shit together to build a direct 76/81 interchange near Middlesex, screw 'em!

[I-55]

Trans-Canada Highway

Alaska Highway

Somewhere in Georgia

Millau Viaduct

Speed Limit 80+

Huh? The well-known trucking route is 15-40-81-78.

That route is 2 hours longer and over 100 miles longer than the I-44 / I-70 / I-76 / I-276 / I-95 routing.

[silverback1065]

United States:

- Clinch US-20
- I-17
- I-5
- I-95 (already driven a little bit of it in Florida but I want to drive it in the Northeast/Mid Atlantic)
- I-376

Outside of the United States:

- BC-99
- Ontario 401
- German autobahns

i-17 is a fun drive. especially if you drive south. some of the steepest grades i have ever driven.

Does the I-44 route go through more big cities?

What's so special about i-40?

Pixel 5

It's probably among the more interesting of the x0s. Actually makes it to coastal states on both ends, unlike 20 or 30, probably more interesting scenery than 10 or 80, doesn't send you through the congested northeast like 90. I want to clinch it sometime too (I'm a little over halfway there at this point).

Not that it makes an interstate worse, but doesn't I-40 go through the least metro area population of the x0s? Unless the LA area goes all the way to where I-40 is, there's not that many large metro areas on 40 compared to 10, 20, 70, 80 and 90.

Expressways in China and Japan.

California Highway 1 along the Pacific coast.
Cabot Trail in Nova Scotia
US-199 in Oregon / NORCAL (one of eight US routes I've never driven - guess the others)
US-730 in Oregon / Washington
US-285 in New Mexico / Colorado
US-491 in Colorado / Arizona / New Mexico
US-57 in Texas
US-181 in Texas
US-310 in Wyoming
US-212 in Montana

[kennyshark64]

Blue Ridge Parkway / Skyline Drive in their entirety (I've been on parts of both)
U.S. 2 in Michigan's U.P.
I-10 in its entirety (so I can have the full coast-to-coast experience)
I-81 in its entirety (only been on part of it)
I-68 in its entirety (only been on part of it)

[silverback1065]

To properly enjoy california 1 you have to go south, and also not be the driver!

To keep my post reasonably short, I omitted some interim connections: 270/255 around St. Louis, potentially 465 around Indy, 270 around Columbus (depending upon when in the day they were to be traversed), and, definitely, 470 around Wheeling.  I've actually done the run in segments, so there's a bit of leeway necessary rather than just plow through the various cities on the principal trunk route.  Hey, if the Kilpatrick around OKC was an Interstate, I'd probably use it as well.

[achilles765]

1. All of IH 10 from coast to coast (done from San Antonio to Jacksonville but only remember San Antonio to about gulfport
2. All of IH 90
3. IH 70 through Colorado
4. All of IH 35
5. IH H3

[jaehak]

Going to the sun road
US 191 (alll)
BQE (been on part of it but I dig urban substandard freeways) or GWB
Here (Saigon) to Hanoi without using the QL1A
That one super dangerous highway in Bolivia

I've done a lot of the roads mentioned on this thread. 70 west is awesome, exceeds its hype. So does Big Sur. 50 in Nevada was a good time. Don't get all the 40 love, it's ok in CA, AZ, NM but boring by CA, AZ, and NM standards, boring as hell in OK and TX, and while the scenery from Nashville to Statesville was nice, traffic was abysmal the one time I was on that stretch.

Depends on what day, if you do 1 on weekdays and outside of the summer season you ought to be fine in both directions.  CA 1 also has some incredible driving segments which I wouldn't want to miss as a person who likes fun roads.  Amusingly on Gribblenation we have most of CA 1 logged going northbound instead of south.

Then why do the trucks take the more southerly route heading east out of OKC? The cost of the tolls in Oklahoma and Pennsylvania?

Diesel in Tennessee is 23 cents cheaper than Illinois, 24 cents cheaper than Indiana and Ohio. Would that be enough to make it worth a route that's 100 miles longer?

[ClassicHasClass]

Australia Hwy 1 and the Iceland ring road. "Some" roads in Japan.

I already did US 6 from CA to MA, but might be fun to do US 50, even though it goes to some of the same places.

I'd argue that, unless cities are the attraction of a particular journey, avoiding large metros is a good thing.  I'm not particularly fond of gridlock, construction, and aggressive driver concentrations.  I've done all of I-40 west of I-81 and all of I-70 west of I-35, I-80 and I-90 west of I-29, I-82, I-84 between I-80 and I-82 and other than I-70 between Denver and I-15, and I-90 through the Panhandle of Idaho and the Bitterroots of Montana, I-40 is the most interesting of the E/W Interstates and is much less likely to close in winter than any north of it.

These are my bucket list roads:
1). Pan-American Highway - North/South America from tip to tip (except the Darien Gap.  Don't have a deathwish)
2). Going-to-the-Sun Road - Glacier Natl. Park before the glaciers disappear
3). US-101
4). US-395
5). US-62 - El Paso to Niagara Falls on a single trip would be pretty epic

Also in I-40's favor: green chiles.  Though I-10 does go a lot closer to Hatch.

That's what, in my mind, makes I-40 to I-81 a better route than I-44 to I-70, for LA to NY traffic.

After you leave OKC, here's what you encounter on the southern route:

Little Rock (and I-40 just grazes the north side of the city)
Memphis (DeSoto bridge woes notwithstanding)
Nashville
Knoxville
Roanoke (outskirts)
Harrisburg (outskirts)

The northern route:

Tulsa
Springfield (outskirts)
STL
Indy
Dayton (outskirts)
Columbus
Wheeling (outskirts if you take I-470)
Harrisburg (outskirts)
Philly (outskirts)

Plus, if you're driving the routes for pleasure, I prefer the scenery on the southern route. I-40 east of Cookeville to the Knoxville area and all of I-81 in Virginia are, to me, pretty scenic routes. There's really nothing to recommend the northern route in terms of the views until you get to the Pennsylvania Turnpike.

Metros are cool to drive through if there isn't much traffic.
