They just finished adding StreetView to the entire route (from June '19).
However, no '538' shields still at that time (on the mainline).
The
CFEA website lists it as '538'. However, while it seems to be planned as that, it isn't signed as such yet in the field sans those two 'TO' shields. Also seems that they're going to
twin the current segment. So, maybe once that happens, it will finally get the FL-538 'Toll' shields.
So, as it stands, I'll treat the route as a 'S-N' route, as there seems to be a better chance it will get extended to the 'north' sooner than to the 'south'. I can always flip the file in the future if needed, or when it's posted as 538 and hopefully gets directional banners. Till then, I think I'll call it as 'fl.poipkwy'.
