When one travels in the winter even in the deep south then you should always check weather and road conditions. A good source of info is the DOT website for each state and on your cell phone you can check current conditions by dialing 511.
The winter weather that hit the deep south has had an impact on travel throughout the region.
In Louisiana I 10 was closed and parts of the road opened yesterday and the rest today. This is a major route across the southern US and is usually a good route to take to avoid snow and ice that one might see on I 20 or I 40.
Interstates I 10, I 20, I 59 and I 65 in Alabama were impacted.
In Georgia interstates I 20, I 75 and I 85 were all impacted as well as the perimeter I 285 around Atlanta which many people use.
