Exploring the Mighty Soo Locks: A Comprehensive Guide

The Soo Locks, also known as the Sault Ste. Marie Locks, are a system of canals and locks that allow ships to navigate between Lake Superior and the lower Great Lakes. Located in the city of Sault Ste. Marie, Michigan, the locks are a vital part of the Great Lakes shipping industry, enabling the transportation of goods and materials between the Midwest and Eastern Canada.

Historical Significance

The first Soo Locks were constructed in 1855, opening up the upper Great Lakes to commercial shipping. Over the years, the locks have been expanded and modernized to accommodate larger vessels and increasing traffic. Today, the Soo Locks are one of the busiest lock systems in the world, with over 10,000 vessels passing through annually.

Design and Operation

The Soo Locks consist of four parallel locks, each with a length of 1,350 feet (411 meters) and a width of 80 feet (24 meters). The locks raise and lower ships by using a system of gates and water-filled chambers. The process of navigating through the locks takes approximately two hours.

How the Locks Work:

1. A vessel enters the approach canal, which leads to the lock chamber.
2. The gates at the front of the lock close behind the vessel.
3. Water is pumped into the chamber, raising the vessel to the level of the next canal.
4. The gates at the rear of the lock open, allowing the vessel to proceed.

Economic Impact

The Soo Locks play a crucial role in the economy of the Great Lakes region. The shipping industry generates billions of dollars in revenue annually and supports thousands of jobs. The locks facilitate the transportation of various commodities, including iron ore, coal, grain, and finished goods.
