Doesn’t barge traffic stop for the dead of winter in the Upper Mississippi? IIRC, the River can and does freeze.
St Louis (MO) is having some very cold weather. However, the barges could make it to Memphis. They have temps in the 50's for the coming week...
Memphis, TN, since it is a 'transportation/package hub' (FEDEX and UPS) probably would have some facilities for handling the barges...
The EIA article talks about rail disruptions as being one of the problems, and wintry weather would impact truck traffic.
Truck traffic would probably be the fastest and most reliable.
To resolve this problem, the trucks should be on the end where you need to fan out for distribution, and rail/barge could do bulk transport to central points -- in a perfect world...
