Port History

San Antonio overtook Valparaíso as Chile's busiest container port in the 2010s due to its deeper draft and proximity to Santiago (110km vs 120km for Valparaíso). STI (operated by PSA International since 2000) has invested heavily in Super-Post-Panamax cranes and yard automation. The port handles approximately 50% of Chile's containerized exports. A $2.5 billion outer harbor expansion is planned to add 3 new berths with 18m draft.
