Holt Logistics Corp. and the Philadelphia Regional Port Authority today announced they have secured new shipping service to the Packer Avenue Marine Terminal in South Philadelphia that will link directly with burgeoning port operations on the Gulf of Mexico. SeaLand, the intra-Americas regional ocean carrier of the Maersk Group, will launch a new line in 2016, its “Atlantico” service, which will call the Mexican ports of Veracruz and Altamira before making a direct connection to the Packer Avenue Terminal in Philadelphia.
