The small lock at Hiram M. Chittenden Locks, or the Ballard Locks, will be closed from Monday, March 9 through Friday, March 20 for annual maintenance, according to its Web site.

The Large Lock will continue to operate 24/7 and we’ll get the commercial traffic through as quickly as possible," according to Dave Carpenter, the project’s Operations Manager. "All pleasure boats will be using the large lock during this time."

The small lock is capable of handling vessels up to 25 feet wide and 100 feet long while the large lock can be configured to be handle vessels as large as 760 feet by 80 feet.

More than 60,000 vessels pass through the locks each year between Lake Washington and Salmon Bay in Ballard.
