The former Jefferson Davis Highway (now Emancipation Highway) has never had the capacity to back-stop I-95. It can be used in emergencies, but only if one wants to get stuck in a slightly different place with an occasional soda machine within walking distance... A feature one stuck on that road may be able to take advantage of, given the speed one will be going.
And I don't imagine it would be much use in a sudden-onset winter storm, since it's right next to I-95; it's going to get blanketed about as fast as I-95 will, and most of it lacks enough shoulder for plows to get along it if it gets jammed with traffic.
