It worked. 
In St. Louis there are two residential areas near the airport that were bought out in the 1970s for noise abatement then depopulated. They scraped out the houses and there it sits: trees, grass, and residential roads in what obviously was a subdivision. Kinda weird to drive around in. Here’s one of them:
It’s the sorta spiderweb-shaped road pattern just off the west end of the much newer west runway. That long dead neighborhood had a 4th quadrant too, but it disappeared into the airport when that western runway was constructed from ~1998-2005. It also used to extend a little farther west but that’s now submerged under some large warehouse like buildings.
There used to be a similar even larger area off the east end of the airport. Most of that has since been submerged under later commercial warehouse construction. But a small rectangular area maybe 4 blocks by 10 remains to the northeast of the I-70 / I-170 interchange just east of the airport.
Kinda spooky. All the more so for being a manmade kinda-disaster. It was certainly a hugely controversial local political event when it happened. Erasing neighborhoods sounds a lot like what was later called “ethnic cleansing”.
There are exits off ***I-30 in Arkansas that only give access to a two lane highway.
There might not be anything but a stop sign. There’s no businesses. Any gas stations or restaurants might be several miles away.
You need to be familiar with the area or have a good map to know which way to turn at the intersection. Otherwise you might take off down a rural highway. The first town you reach may only have a convenience store with gas pumps.
It’s better today with Google maps. But still can be confusing if tourists are looking for a restaurant.
***I-30 connects Little Rock to Texarkana and then to Dallas-Ft Worth.
That’s a good point. For example, the stretch of I-90 between exits 2 & 3 (about 30 miles) includes the Blandford service plaza, about 11 miles from Exit 3.
The James Bay road in Quebec (385 miles/620 km long) has no facilities - except within a couple of miles of either end. Paved for its entire length. A Hydro-Quebec operated road branches off to the east with gas and food only available at the 358 km mark (414 miles/666 km total length). Gravel road, serving the dams and reservoirs in the area.
Which is still in the running as the site of a possible new exit:
I was going to guess that this was going to the high on the list.
I-80 goes from Wendover on the state line and then straight through desert and Bonneville Salt Flats to Salt Lake.
There are a lot of smaller highways that may have “JCT Farm Road 657” listed, but the actual “exit” looks like this. Would this count?
We’ve got an area that was once lived in, then it was found to be untenable due to repeated flooding.
Is it marked as an official exit?
What you see is what it looks like. There’s a junction sign about a quarter mile back, and another sign with arrows telling you what is in each direction, but that’s it.
It’s an official Texas state highway, and that’s what the actual intersections look like, which is why I ask. There may be NO explicitly labeled exits along a highway like that- you just drive along, there are periodic intersections with other roads, and you just sort of end up in the middle of little tiny towns. But they’re not limited access highways, so they don’t have actual exits.
I’d bet that Texas 86 between Tulia and Estelline doesn’t have a single explicit exit, and that’s an 84 mile stretch. You can probably find a longer stretch elsewhere in the state, or in other Western states. Based on my imperfect recollections, the Deadwood/Lusk stretch of US 85 (Can-Am Highway) didn’t have any explicit exits for 140 miles.
I am talking about actual exits that are marked as exits.
I wouldn’t count something that has only intersections, not exits as the “longest stretch of highway without an exit” . Because the question doesn’t make sense - it’s like asking what’s the longest stretch of highway without a rest area/travel plaza/rest stop and then saying the longest one is a road that doesn’t have any rest stops because there’s no need for rest stops anywhere other than a limited access highway.
Perhaps you should clarify that you only want limited access highways - where you get on and off only at marked exits with on and off ramps. Your OP says “highways/freeways” - freeways are usually limited access but highways may or may not be.
I interpreted the OP as “where are you most screwed if you miss your exit” since on most limited access highways highways U-turns are illegal.
Very strange interpretation of what I actually asked for. Once, again, am looking at freeways and highways, and exit signs that are marked as such, looking for the longest stretch between official exit signs marked as such.
I have never heard “exit” to mean anything other than from a limited-access highway (like an interstate), and I have a lifelong interest in this subject.
That’s why it’s so jarringly wrong when a voice car navigation system uses “exit” to refer to a simple roundabout (traffic circle). “Take the second exit..” — No, you moron, just keep going straight! It’s a roundabout, not an interchange!
I have on a highway doubling as a city arterial, but it struck me as an error in usage.
Yes, I’ve seen that very occasionally, and have the same reaction.
Maybe that particular instance is partly because “intersection” doesn’t fit on a sign as easily as “exit.”
No, it’s just another way of looking at it - unless you really meant to include highways which have unmarked exits and/or cross streets between marked exits. In which case the answer is likely a highway which is limited access in one metro area, non-limited access in another, then limited access in the next metro area. Lots of highways out west like that.
I just wanted a simple fact about distances between official exits on freeways and highways. “I interpreted the OP as “where are you most screwed if you miss your exit” since on most limited access highways highways U-turns are illegal.” brings in u-turns and opinions about being screwed. I put this in Factual Questions just to avoid all that.
How is that opinion? It is a statement of fact - if you are on a limited access highway and you miss your exit, the next legal was of correcting your error in most jurisdictions is to proceed to the next exit, getting off the highway, then re-entering going the opposite direction. If you need to drive an extra 50 miles, that satisfies the definition of “screwed” for 99.99% of the population. So you are “most screwed” when that extra distance is the greatest by being on the longest stretch of highway without an exit.
