New Orleans to Atlanta

[marting]

I'll be taking a road trip in the southern states of America for part of my honeymoon in early October (Dodge Challenger R/T ).

I have a rough loop starting from Atlanta following the Mississippi for a bit, working towards Dallas and then back towards Atlanta via Houston and New Orleans.

I'm not sure what to do for the last part of the journey from New Orleans to Atlanta, any good roads or sites between these?
