The Chicago Harbor Lock reopened today after a five-month closure to reconstruct the north chamber wall, and normal lock operations are now in place.

“Exploratory demolition was conducted and interim repairs completed,” said Tim Kroll, chief, Operations Branch, “Wall resurfacing will continue over the next two winters into the spring of 2024.” 

The Chicago Harbor Lock, located in Chicago and adjacent to Navy Pier, separates the waters of Lake Michigan from the Chicago River. It is one of two entrances from the Great Lakes to the Illinois Waterway System.
