STRATEGIC IMPORTANCE
  • Soo Locks system is the busiest lock system in the world by cargo tonnage,

  • Handles an average of 7,000 to 10,000 vessels annually, 

  • No alternative mode to move iron ore from Minnesota mines to the lower Great Lakes, and

  • The value attributed to iron ore shipped through the locks each year is $500.4 billion.

The Soo Locks complex is the lynch pin of the Great Lakes Navigation System and is considered to be nationally critical infrastructure due to their national economic importance and impact on national security. Ten out of eleven integrated steel mills in the Great Lakes region depend on iron ore and other materials that must transit the Soo Locks. The Soo Locks complex consists of 4 locks, however the Poe lock is the only one capable of handling the largest commercial vessels known as ‘1000-footers’. The Poe lock was constructed in 1968 and undergoes substantial maintenance to function reliably. A second Poe sized lock has been pursued for decades as an extended lock closure would have devastating impacts on the U.S. steel, automobile and other industries. The additional Poe-sized lock would replace two existing small locks at the complex.

The project is estimated by the United States Army Corps of Engineers (USACE) to have annual net benefits of $44.7 million with a benefit-to-cost ratio of 2.42 based on a June 2018 economic validation report.
