Seaway Development refers to the enhancement and expansion of waterways to facilitate navigation and transportation. This includes the construction of locks, channels, and ports, which allow larger vessels to travel efficiently. Such projects often aim to boost trade and economic growth by connecting inland areas to global markets. In the context of the Great Lakes and St. Lawrence Seaway, Seaway Development plays a crucial role in supporting shipping routes. It helps industries transport goods like grain, coal, and manufactured products more effectively. Improved infrastructure can lead to increased shipping traffic and job creation in surrounding communities.
