Animated map illustrating how 3-digit US routes were intended to be numbered

East to west, sequentially (or north to south).  More: https://www.usends.com/numbering.html

Too fast of a rate.  Feels too jumpy.

I realize this would require some coding skill, but the optimum path would be an interactive, scalable map instead of animation.

Rate seems fine to me. What I don't like is how it goes back east after going west. Just have it loop to the beginning once it reaches the west end.

Historic 330 is still mostly there as Illinois 38 which follows 88. I have a map where there was a toll 30.

Historic in the sense that it is no longer signed as US 330.  I'm sure all the historic roads mentioned are still drivable roadways, they are just no longer US x30 highways.

That is cool

Of the x30's, I believe US 830 should be resurrected as it is a valuable alternative and could be made to go through two states. US 30S goes through three states as well, but could be US 32 easily as that number has no historic value (being replaced by US 6). Former US 30 Alternate is also a useful route, replacing NE 92 and IA 92. US 230 could be re-purposed there (if it doesn't conflict with state highways).

If upgraded to an Interstate, US 30 in western Ohio can return to its old route, while US 330 would become useful by running into Indiana (with IN 49 the best return route). Former 230, 430, 530 and 630 serve no purpose that wouldn't be accommodated by a state highway (too short or single state route) and were rightfully decommissioned.

US 330 was Alt. US 30 between 1942 and 1972, after which it became IL 38. 

Toll US 30 was the East-West (now Reagan) Tollway, which later became IL 190 (1960s), IL 5 (1972) and I-88 (since 1990).
