Inside the Seaway's Aging Locks

Listen to this story
The locks and channels of the Great Lakes-St. Lawrence Seaway system are getting old. Some were built more than 75 years ago. The U.S. and Canada are conducting a multi-million dollar study to determine how to keep the aging waterway functional, so ships can continue to haul cargo between the Great Lakes and the Atlantic Ocean.

David Sommerstein climbed eight stories down to the bottom of the Eisenhower Lock on the St. Lawrence River near Massena to see how it's aging.
