Scenic routes through FL.
Why limit yourself to the confines of a computer programme. If you were to pop over to AAA and get their map of FL (free to members), you will see the details of all the routes available to you, and places along the way.
There are some very scenic routes through FL with small towns and antique malls along the way. These are not all necessarily much slower than the interstates. US27 and Alt27 to Ocala is a four lane highway divided road. I also recall in the vicinity of Chiefland seeing a sign to the Quilt Museum.
From Ocala to I-95 FL-40 is a lovely, albeit slower, scenic route. Down the coast you could take I-95 with periods of respite along US-1 and A1A along the coast.
You might be interested in The Arcade building with its magnificent murals, at 101 on US-1 in Fort Pierce.
