Curious, but are the putting green-outs over the FL-9A shields, or are they installing entirely new signs?
I've only been between UNF and the south I-95 interchange as far as the East Beltway goes, but it looks like for the most part, they just slapped I-295 shields over the old SR 9A ones on the BGSs, with new reassurance signs at the appropriate locations.
The only place I've seen brand-new signs is around the I-95 interchange: heading south on the West Beltway, the signs mention you're about to go north on I-295 East Beltway up until the Philips Highway (US-1) exit (although some of those are green-outs), while coming south on the East Beltway, the signs start referencing I-295 West Beltway from just before US-1 to the first BGS past the I-95 interchange.
The BGSs on J. Turner Butler Blvd (SR 202) heading for the East Beltway also have the 295 shield where the 9A one used to be. Coming south on I-95, the signs still refer to I-295 and SR 9A separately; haven't come north in a while.
