A pretty neat info-graphic showing the estimated populations within each area of the US entirely bounded by Interstate Highways (not by me, just sharing): http://www.statsmapsnpix.com/2023/04/intra-interstate-populations.html
The actual map doesn't have this error, but when they're showing things, US 36 near Denver gets upgraded

Also I-37 in Indiana, and I-446 on the "outside" map somewhere in/near Kentucky
This is absolutely fascinating. Thanks for finding it. The area where I grew up has a smaller population than I thought, 913,483, since the metropolitan area is divided up by Interstates.
Dang, nearly 9,000 just in the 270/495 triangle...
I wonder how exact this is. How are they able to determine the population so precise as zip codes and other normal population metrics aren't aligned and bordered by highways?

Census data has the ability to go more granular than that. Blocks and block groups are usually bordered by roads and highways.
For example, the census block I live in contains a handful of houses and is bound by residential streets on four sides.
