It likely shipped salt by package freighter back in the days that salt was shipped in wooden barrels, but I don't think that it ever shipped salt in un-packaged bulk quantities. Keep in mind that the only salt mine in Michigan that uses traditional underground mining techniques is the Detroit Salt Mine. Cargill at St Clair and Hersey, Morton at Manistee and others use solution mining to bring brine to the surface for evaporation. So they don't produce near the volume of salt as underground mines do. Solution mining plants tend to cater to producing food grade salt, water softener salt and brine products for chemical manufacturing. The underground mines (Detroit, Windsor, Goderich, Cleveland, Fairport, etc) tend to cater to the high-volume de-icing (road salt) trade.
Here is an old steroscope card from St. Clair back in the day.
