Longest A to B within a state

[webfil]

Might be fun to do Canadian provinces.  Those distances can be pretty big, but Nunavut's is probably surprisingly small due to the lack of roads up there.

The three largest provinces :

Québec : 1,450 miles/31 hours

Ontario : 1,305 miles/23 hours
http://goo.gl/maps/B4YdX

British Columbia : 1,251 miles/25 hours

Up to Windigo Lake via Pickle Lake is a lot further than straight to Manitoba.

Are ice roads allowed? I can add about 20 miles onto Ontario using the Weagamow Lake Ice Road.

Beat by over 200 miles:

Looks like I got 2,386 km for Ontario: http://goo.gl/maps/CgJbA

Found a road that is further away (2489 km): http://goo.gl/maps/ilml5

Note: it's not cheating if it's the minimum necessary to stay in state/province.

Nova Scotia: 809 km, 9 hours 29 minutes

It is LITERALLY IMPOSSIBLE to beat 809 km for Nova Scotia.

Fixing your quote (miles->km)

LITERALLY IMPOSSIBLE

I do not think those words mean what you think they mean.

I got 907 miles for Manitoba. 19 hours, 10 minutes. http://goo.gl/maps/wTjEf

Again, ice roads?

It may be possible to beat 809 km, but it actually is literally impossible to beat 809 miles.

For Wisconsin, the longest distance in as straight a line as possible using county, state, us and interstate highways is from Russell Rd (IL State Line) at Wis 32 in Pleasant Prairie to US 2 Bong Bridge in Superior.

Quickest route (via I-94, I-894, I-94, US 53, US 2) - 436 miles, 6 hrs 32 min

[Alps]

It may be possible to beat 809 km, but it actually is literally impossible to beat 809 miles.

That's fair. It is also literally impossible to beat 50,000 miles for longest A to B anywhere on this planet.

Since you guys started looking at other countries, I took a shot at Britain.  It could be longer if ferries to Scilly or Orkney were allowed, but I decided to stop at the beaches.  This clocks in at 843 miles, 13h 55m... about the same as Florida

http://goo.gl/maps/XJfzL

And here's Ireland: 589km, 8h 20m.

http://goo.gl/maps/n94EI

Moving the northerly endpoint just across the Lough to the east adds another 100km or so, but not only does it route through "the north" but also through motorways via Dublin which seems to me a silly diversion off course, regardless of how narrow the westerly route may be.


Also I like the idea of a Cape Town-Magadan road trip.  It may be useful to have multiple spare tires, months off, and passports for that one.

I don't think the OP ever actually prohibited ferries. I was the one who first mentioned a ferry. I had measured out a distance in Alaska of over 1,000 miles and said I could push it to 1,800-some miles over 70-something hours by moving the endpoint to Unalaska, but that it probably shouldn't count because it uses a very long ferry ride. The reasons I thought it shouldn't count were that (a) the time factor is clearly out of whack on a ferry like that because it doesn't take 77 hours to drive 1,800 miles and (b) the ferry ultimately takes you to a dead end (can't go further than Unalaska) that requires you to turn around and ride the same lengthy ferry right back where you started from.

The ferry across the Red Sea others have mentioned is far more direct, for example, and I think it'd be reasonable to count something like that. I suppose it might be reasonable to count the Euroshuttle (or whatever the current name is for the auto train that uses the Chunnel) and the ferry from North Sydney to Port-aux-Basques that connects Nova Scotia and Newfoundland. All of those are major through routes and you can keep on going after riding them.

Someday, when the Bering Strait is bridged and the Darien Gap is filled, you'll be able to drive from Cape Town to Ushuaia.

Similarly, from the southern tip of Sweden to the northernmost point on its highway network (E10 at the Norwegian border north of Kiruna) is about 1,256 miles and 21 hours of driving.  There's a fair amount of Swedish territory north of there, but there are no highways in Sweden (there are some in Norway). 

Across the sea in Finland, the longest possible trip appears to be from the southern port city of Hangö, to a small secondary road overlooking Norway at about 875 miles and 16 hours.

Speaking of Norway, from Kristiansand on the North Sea to Kirkenes near the Russian border is about 1,700 miles in 35 hours, using an all-Norway route (mostly E6).  A more-direct routing is across Sweden and Finland, which reduces the distance to a little less than 1,400 miles in 27 hours.

Longest I could find for Vatican City was 1.1 mi (1.8 km)

I didn't.  I have no problem with routing via ferry if it's realistic, i.e. you can drive on/off, it's fairly frequent, and it's a route that makes sense.

I never mentioned it because for the most part (the interesting Alaska example notwithstanding) it doesn't really apply to US state routings.  However, the Red Sea ferry in the "world" routing saves time and distance, and also manages to avoid some trouble spots as well.  Makes sense to me.

Taking the ferry for this route for Washington saves 50 miles, but adds an hour and a half.  (The non-ferry route beats what kkt posted on page 1 of this thread by about twenty miles.)

Good. https://maps.google.com/maps?saddr=48.962737,-117.096859&daddr=48.284564,-124.620391&hl=en&sll=48.282379,-124.619722&sspn=0.011552,0.021372&geocode=FbEc6wIdZT4F-Q%3BFZTD4AIdmXGS-A&mra=ls&t=m&z=7 gets up to 592 miles.

I don't think it gets any longer than just sticking to US-89 in Utah. 502 Miles per Google Maps.

Actually, US-89 from Arizona line to US-6, US-6 to I-15, I-15 to I-84 WB, UT-30 west to Nevada line is longer (though it is circuitous, going around the Great Salt Lake and all). 577 Miles.

Arizona's seems to be AZ-389 at Utah line to US-89A, 89A to US-89, 89 to US-180 near Flagstaff, 180 to I-40, 40 to I-17, 17 to I-10, 10 to AZ-80, 80 to US-191, and US-191 to Mexican border (AKA Colorado City to Douglas). 603 Miles.

Longer for Arizona: http://goo.gl/maps/hZajm : 639 miles.

You cheated with the second Utah one: WAY too many reroutes.

Wasn't sure about the exact rules. And shoot, why didn't I think of sticking to AZ-80?

[NE2]

You don't even need to cheat to get 575 for Utah. Just minimally keep it out of Nevada by adding a point on SR 30.

428 miles using the shortest suggested route by distance (although not the fastest). There are two faster routes that are longer in distance.

Can't get to Google Maps out here, but theoretically for Minnesota, the longest would either be New Albin, IA (MN 26 at the Iowa line) to Noyes (US 75 at the Canadian border) or the MN/SD/IA tri-point to Grand Portage.

The MN-SD-IA tripoint to the end of Sag Lake Trail (a spur of the Gunflint Trail) is actually longer at 576 miles, versus the tripoint to Grand Portage at 562 miles (the quick and dirty way of just using the interstates). Noyes to New Albinat 547 miles if you route it all in MN, is out of the question.

Here's the longest possible route in Minnesota, unless someone can think of something longer. http://goo.gl/maps/jJX1Y

If short jaunts in other states on the route are allowed, the southeast point to the the Northwest Angle is 589 miles.

I sure couldn't pay for *that* much gas, I'm doing good to get back and forth to work!
