We haven't taken this route but we have some friends who suggested it to us. Northbound, they stay on I-75 to Tifton, GA and then take Hwy 82 over to 231. It intersects with 231 just south of Montgomery.
The Atlanta highway collapsed I believe on Thursday evening, the 30th. Did you leave Orlando on Friday, the 31st? If so we never leave Florida one to two days either side of April 1st. Traffic is terrible with all the snowbirds leaving the state.
We have taken the I-10/231 route the past 4 years and really like 231 overall. The section thru Dothan has gotten worse with more and more traffic lights but looking at the big picture it's a nice drive either side of Dothan, all the way north to Montgomery and south to I-10.
