Bikable roads (westbound) from Anniston to Mississippi

[Bicycle Rider]

I need recommendations for building an east to west route crossing Alabama from Anniston (west end of the Chief Ladiga Rail/Trail), to the Mississippi line. Because of my final destination, I cannot wander too far South than Interstate 20. Any recommendations for U.S. or State highways, roads or cities/towns I might use or should avoid, please post suggestions here. My journey will be a self contained combination of camping and motel (I preffer camping)

The A.C.A. Southern Tier is not an option, as it will add over 8 days to my journey.
