Ok, from watching the video there, I can make out the following Exit #'s.
53 for International Parkway
54 for I-4
All that leaves is the exit number from where it shifts from the FL-46 corridor. OSM says 52, but I'd like confirmation on that first before I make the update (could be posted as 51, who knows, but 52 would seem right).
Plus, wasn't even aware that they had opened the segment from Exit 50 to 52(51) before the connection from I-4. You're slacking there NE2.
