Per the 2013 state highway log (https://www.azdot.gov/docs/default-source/planning/2013shslog.pdf?sfvrsn=2), AZ 189 has been truncated to begin at the north end of the US customs facility rather than at the Mexican Border itself.
On page 442:
Begin S 189 NB 0.34 miles inside AZ at Nogales Intl Border POE

Some California state routes are like that (CA 7 and CA 111), and I've truncated them to start north of the U.S. customs station. Others aren't, like CA 188, and CA 186 (where the End CA 186 sign is south of the last chance to turn back before entering Mexico), and I've treated them as starting right at the border.
Truncating AZ 189 would break the connection (shown in TM) with the Mex 15D toll road west of Nogales, whose north end was placed at the border.

I would not truncate it and keep the connection to the Mexican road.
Mark topic solved.
