Study defines value and challenges of Mississippi River shipping channel

A single stretch of water can set the tone for global prices, rural incomes, and the cost of everyday goods. We dive into the Mississippi River Ship Channel with Ken Erickson of Polaris Analytics and Consulting and Sean Duffy of the Big River Coalition to unpack new, verifiable numbers that quantify its outsized role in U.S. trade. The study pegs $226.5 billion in annual value moving through a corridor that links Midwest barges to ocean-going vessels, stitching together grain exports, fertilizer supply, refined products, coal, cement, aggregates, and more into a single, high-throughput system.We explore how reliability turns into real money: why every foot of lost draft can raise ocean freight rates about 2%, how brief closures ripple into weaker basis for farmers, and where those costs land first in local communities—lost output, fewer labor hours, and thinner tax receipts. The conversation traces supply chains from Baton Rouge past New Orleans to the Gulf, highlighting five deepwater ports that together handle nearly 500 million tons a year. We also address policy head-on, showing how hard data—sourced from vessel agents, customs districts, and industry partners—strengthens the case for sustained dredging and smarter infrastructure funding.If this story of data, infrastructure, and competitiveness speaks to you, follow the show, share it with a colleague, and leave a review to help others find it.
