Wikipedia:WikiProject U.S. Roads/Mississippi/All-time list
Given are the years of the first and last official maps the routes appear on. These are not always the exact years the routes were created or eliminated. In particular, numbers were assigned in about 1929, but the first map with numbers is 1932.
A number of three-digit routes (including all locally maintained ones?) are missing from maps starting in 1967. I don't know if this means that unmaintained highways were completely removed from the system, or if they had signage removed, or what.
