Just got back last night....
Between Tifton and Valdosta there is still several miles' worth of construction, but it's better that it was several months ago. Then you're clear until the Fla. Turnpike, where the construction is a bit of a mess just before the Hwy. 429 (Daniel Webster Western Beltway) exit. The exit from turnpike to 429 is horribly marked, and sneaks up on you fast. They've changed it from the way it was back in March and December, so that it's a longer off-ramp... meaning you've got to be ready for it sooner that you used to..... but maybe you go the other way down to I-4. If so, you don't have to worry about that.
