Corps Awards Contract for Mississippi River Navigation Improvements

Why It Matters

Modernizing the kevels safeguards reliable upstream navigation, preserving a low‑cost, low‑emission freight route essential to supply‑chain resilience and national security.

Key Takeaways

• $12.8M contract awarded to Kramer North America.
• Upgrades target traveling kevels at Locks 2 and 3.
• Construction slated Nov‑2026, finished before 2027 season.
• No navigation disruptions expected during work.
• Mississippi lock‑dam system moves over 10M tons annually.

Pulse Analysis

The Upper Mississippi River remains one of America’s most vital inland waterways, carrying more than 10 million tons of bulk commodities each year through a 9‑foot navigation channel and 13 lock‑dam structures. A single 15‑barge tow can replace the capacity of 216 rail cars or 1,050 semi‑trucks, delivering goods such as grain, coal, and aggregates with far lower fuel consumption and emissions. This efficiency not only eases congestion on highways and bridges but also supports the nation’s agricultural export engine and regional manufacturing hubs.

The lock‑dam complex, much of which dates back nearly a century, relies on traveling kevels—adjustable steel plates that guide towboats through lockages. Over time, wear and corrosion can impair kevel performance, increasing the risk of delays or mechanical failures. The St. Paul Engineer District’s $12.8 million award to Kramer North America targets the kevels at Lock and Dam 2 in Hastings and Lock and Dam 3 near Welch, with construction slated for November 2026 and completion before the 2027 navigation season. By addressing these critical components now, the Corps aims to preserve uninterrupted upstream traffic.

Beyond the immediate engineering fix, the project reinforces the broader strategy of modernizing America’s inland waterway network to meet rising freight demand and climate‑resilient goals. Reliable river transport reduces reliance on diesel‑heavy trucks, cutting greenhouse‑gas emissions and extending the lifespan of overburdened road infrastructure. Moreover, a dependable lock‑dam system is a strategic asset for national security, enabling rapid movement of military equipment and supplies. As the Corps continues to prioritize preventive maintenance, stakeholders can expect steadier shipping rates and fewer supply‑chain bottlenecks in the years ahead.
