Traveling thru Alabama to Florida

Don't give it a second thought. In my opinion this is the absolute best route south if it doesn't take you too far out of your way. Adds maybe an hour for me but great roads, bypasses mountains and traffic. I've used it the past two years but this year we are going to have a couple stops along the east coast so we're going to have to take the less desirable route on the way down at least.
...oh, and no low bridges to worry about.
