"311" is to KKK fascists a code for "three K's" or "Triple K"... you know what that is. Think also of the special significance that "88" (H as in Heil, and H as in Hitler) and "18" (A as in Adolf and H as in Hitler) in Nazi parlance. For most people those numbers have no such significance. There is, for example, a US 311 between Danville, Virginia and Winston-Salem, North Carolina. (Until 2019 it extended southeastward of Winston-Salem, but of Winston-Salem, but that highway was removed.
Removing a highway designation for an association with an infamous number has been done, as with US 666 (Mark of the Beast in Revelation 13:15–18). US 666 has been infamous as the "Devil's Highway" for a high rate of vehicle crashes and fatalities.
The reason they renumbered US 666 was that idiots kept stealing the signs.
