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.
