Congratulations, I'm sure you'll enjoy it, we just returned on Sunday the 20th.
There was a moderate amount of construction on I-95 for about 40 miles from just south of Jacksonville until beyond St Augustine. It looks like they're starting to make a third lane for I-95. They had those old orange barrels out and it was somewhat congested but we never slowed down much below 60 at any point.
The checkin process at the Terminal seemed to take much longer than before. They moved the carryon luggage scanners down to the entrance of the terminal and it seemed to take longer than before, maybe I was just impatient to get onboard.
hope that helps
