I am not sure if I am too fond of those flange design......in my area....if there was a 2 piece connection like this....instead of the flanges, they slip one pole into the other pole (one being slightly smaller than the other) and then put a big bolt or 2 through the holes....
But I have seen such flange design in Colorado for the freeway highway signs and some traffic light poles in Long Island area (outside of New York City) and I think some in Arizona...

The newer signal arms here are mounted with either a clamp or mounted with through bolts.
I haven't seem a arm that was spliced here because most signal arms are short enough to be a single piece.
