A pilot-and-weather station, designated anchorages and a roughly 13.7 m channel mark Southwest Pass, the seaward gateway to the Mississippi rather than a cargo port in its own right. The river's main shipping channel since 1853, it is where Mississippi River pilots board inbound vessels and guide them across the bar and upriver from the Gulf of Mexico. No containers, breakbulk or customs clearance are handled here; cargo is worked at the terminals upstream. For actual freight, New Orleans, the Plaquemines terminals and Baton Rouge are the relevant ports.
