St. Louis Port Authority

The Port Authority of the City of St. Louis supports economic development in the City’s 6,000-acre Port District, which lies along the City’s 19 miles of Mississippi River frontage. In addition to managing leases for City-owned property in this area, the Authority works with shipping stakeholders across the bi-state area to promote regional commerce.

Port Authority Activities

      The Port of Metropolitan St. Louis is also located in the heart of a 15-mile stretch of the Mississippi River that has become known as the Ag Coast of America. It is home to 15 barge-transfer facilities that, at total capacity, can handle 150 barges a day – the highest level of capacity anywhere along the Mississippi River.

      The St. Louis region’s port system is the second-largest inland port system in the United States, and was ranked the most efficient port system by the U.S. Army Corps of Engineers (2018 data). The St. Louis regional port system is responsible for 8% of the 855 miles of the Mississippi River, but carries one-third of the river’s total freight. In 2018, the region’s barge industry handled more than 534,000 tons per mile – more than 2.5 times more efficient than the closest competitor.
