Yes, OKDOT applied to AASHTO to delete them both at the same time.
I waited a long time for the signage removal to show up in GMSV. Eventually, US70Bus was gonzo but I didn't see enough change to convince me to remove US271Bus yet.
On the one hand,
all NB signage is now gone -- except for
this rather big exception. Good effort OKDOT in getting rid of the business banner here, but it falls a bit flat when the rest of the route more often than not was signed as plain US271 rather than business. Strong implication there's some flavor of US271 here -- something that's not a bypass.
SB is another story; other than at Jackson (old US70Bus) & Broadway where all signage was removed, the only sign removed was
the one SB one that actually had a banner.
Unless something has more recently changed on the ground,
we still have all of these.
