I remember my Dad teaching me about highway numbers back when I was a kid, so I know that the 4 means it’s part of a loop, being odd means it runs mostly N/S, and being a low number means it’s on the west side of the US.
The Dewey Decimal System is still a mystery to me, though…
I believe if the first digit is even in the 3 digit highway number, it connects, if it’s odd then it doesn’t. There’s a cool video about it by cgp grey and a whole Wikipedia on it
