Dang, out of gas! Well, I’ll just walk a ways, I’m sure I’ll run into something. 
Some days math is harder than others. Happens to all of us.
I don’t know if this would qualify, but the Dalton Highway (the pipeline road) in Alaska only has three inhabited areas. The stretch between Coldfoot (pop. 34) and Deadhorse (pop. 25-50) is 240 miles. There are no services in that stretch of road, so it behooves one to gas up at both locations.
And, except for Yeehaw Junction, much of the same for those stretches of Florida’s Turnpike: swamps, farms, and wildlife management areas.
I love #15 in PA; indicates there’s an emergency entrance / exit they can open up. There have been a few cases over the years where a snowstorm shut down the road; people stuck for something like 25 hrs & emergency services/National Guard running them emergency supplies of food/water/fuel. Do you think if they can’t manage to keep a high-volume interstate passable that the 2-lane local, rural road is going to be better or worse?
Nitpick: Thruway.
Sorry…a fascinating post, and thanks! For real.
Why are there 2 lanes of water running parallel to the road?
Drainage canals. The Everglades (and all the way up to Lake Okeechobee) are a mass of water slowly moving southward through soil and grass.
I-15 as it goes through the whole state of Arizona has only 2 exits over the entire stretch.
Two on each side, or two total?
It was after, but I was only nearby, not actually there. I was on I-55 and stopped to take a picture of the exit sign. So I think I was about 5 miles east of town.
I-15 only cuts through the north west corner of Arizona, just 30 miles, so it’s not surprising that there aren’t many exits.
It looks like there are 4 exits (each on both sides of the highway)
- Exit 6 - Beaver Dam Littlefield
- Exit 9 - Desert Springs
- Exit 18 - Cedar Pocket
- Exit 27 - Black Rock Rd
Yeah it just nips a tiny NW corner of the state.
This drive is still on my list of Things toDo, Places to Go, and People to See!
(I’ve only been talking about it for over 10 years…)
I’ve been to Centralia, PA; the roads are still there, but that’s it. Not a house left. More eerie than Erie ( PA)!
I thought the longest stretch was between any two exits in L.A.
If you’re going on elapsed time rather than physical distance, you’re probably right. 
I know; drove it many times. Just trying to make it sound more impressive than it really is.
Thanks. It kept looking wrong to me but I couldn’t figure out why!
I think many of those routes in the northeast were originally built as toll roads. Thus they wanted to limit the places where drivers could enter and exit in order to reduce the number of toll plazas needed. I believe those routes do have service plazas where you can stop for gas and fast food.
