Longest distance before next turn/fork in road?

When creating a route on a GPS device, what is the longest possible distance before the next turn or keep left/keep right instruction? For example, when I drive down to my parents' house near Daytona Beach, the next instruction on I-95 south after passing Fayetteville, NC is about 385 miles away in the Jacksonville, FL vicinity. (I forget if it was at the intersection with I-285 or I-10).

Not sure what you are asking, but I have had the unit tell be to drive well over 300 miles to my next turn if there are no other directions it needs to issue.

Dave, I had my nuvi plot a route from the Lower 48 to Whitehorse, Yukon. One instruction was to turn right on Robert Service Way in 871 miles. I bet a route to Delta Junction AK from the Lower 48 could have distance of over 1000 miles before the next turn.
Then again, maybe even a longer stretch can be calculated for an east-west route along one of the Atlantic to Pacific Interstates.
Longest?
I've had my gps tell me to drive 24,901 miles to my next exit, which was 1/2 mile away! Guess it wanted me to take the scenic route!

You turn

Wow, so a GPS will very strongly & literally follow your choices when you tell it to avoid U-turns...
Re: Longest Distance
24,901.463 miles is the the measurement of the Earth's circumference at the equator.

That was input from the oil companies! LOL
NUVI 680, NUVI 5000, MS S&T,
Interesting ride
It would have been an interesting ride, but, this truck don't float!
And the fuel! 24,901/7.5*$4.45= $14,774.59. Now add that to your grocery bill when you go shopping!

My C330
will tell me long distance turns if I'm going out of town. It is usually just a direction change on the highway I'm on.
Not doing anything worth a darn.
Actually, Haines AK is further

Just for fun, I decided to test out some routes to see what long stretches came up:
1. If driving from the Lower 48 to Alaska, there is a 969-mile turn-free stretch from Dawson Creek, BC to Haines Jct, YT. After making a right turn to continue up the Alaska Highway, there is another turn-free stretch of 493 miles to Fairbanks. (I thought there would be a turn at Delta Junction, but apparently there isn't.)
2. Even better, if you select Haines, AK as your destination, the turn-free stretch from Dawson Creek is 1116 miles! To get this routing, though, you have set up your GPS receiver to "avoid" ferries, since there is a much shorter route that takes you to Skagway, AK, where you then take a ferry to Haines.
3. For routes from eastern USA to Seattle, there is an 832-mile turn-free section of I-90 between Dakota, MN and Buffalo, WY. If taking the more northerly route, there is a 1030-mile turn-free stretch along I-94 and I-90 from Albertville, MN to Butte, MT. Finally, the turn-free "home stretch" from Butte to Seattle is 587 miles.
4. Along I-5, there is a 544-mile turn-free stretch from downtown Portland to the I-5/I-505 split north of Sacramento.
5. Along I-80, the stretch from Reno (jct US 395) to Salt Lake City (jct I-15) is 515 miles. The stretch from the I-84 junction in eastern Utah to the I-76 junction in Nebraska is 534 miles.
6. Along I-70, the turn-free stretch from the I-15 junction in Utah to the Denver area is 493 miles.
I'm going to test out some more later, particularly in remote areas of Canada.
