It’s Kafkaesque that in a world with such smart machinery, the ability to code to infinite hierarchies of logic, and no practical limits on the storing of human knowledge, a country as big as America can’t handle diversity in its exit numbering schemes.

There is a practical reason to number by mileposts. For one thing, it saves the trouble of renumbering exits or adding fractional exit numbers when new exits are added.

The New Jersey Turnpike is keeping the sequential numbering system. I believe it is exempt from the Federal regulations because it was built before the Interstate Highway System was established. It’s ludicrous to see how they added exits like 7A, 8A, 15X, etc. over the years.
