Offering a gateway to the Gulf of Mexico, the Alabama State Port Authority (ASPA), a government agency, operates the deepwater port facilities in Mobile. The port complex includes facilities for handling general cargo, such as containers, forest products, and metals, as well as liquid bulk and dry bulk cargo, such as chemicals, coal, iron ore, and steel. The port complex features more than 4 million sq. ft. of warehouse space and open yards and almost 40 berths. A 75-mile rail line links Port of Mobile facilities and provides connections to major freight railroads. The ASPA began operations in 1928.
