Hiram M. Chittenden Locks

Definition

The Hiram M. Chittenden Locks, also known as the Ballard Locks, are a complex of locks in Seattle, Washington, that facilitate the movement of boats between Puget Sound and the Ship Canal. Named after Colonel Hiram M. Chittenden, the locks were completed in 1917 and play a crucial role in maritime transportation by allowing vessels to navigate the significant elevation differences between these two bodies of water. The locks are not just functional; they also represent an important engineering achievement and have contributed to the growth of settlements in the region by improving access for trade and transportation.
