The small lock at Hiram M. Chittenden Locks will be closed two weeks for repairs following Sunday's boat crash.

The small lock was damaged when a vessel malfunctioned and could not disengage its engines on Sunday afternoon, hiting the lock gates. Quick-acting lockwall staff were able to clear visitors prior to impact.

U.S. Army Corps of Engineers structural engineer Mike Likavec and Lake Washington Ship Canal maintenance staff inspected the gates and anchorage on Monday and determined that repair will take about two weeks.

“Safety is our primary concern, and in the coming months we will re-inspect the gates on a routine basis to identify any signs of distress from the incident,” Likavec said.

Corps workers have begun repair work, which officials estimate will cost $10,000 to $20,000.

The small lock will remain closed to all but police and fire vessels on emergency response until structural members of the walkway, which help protect the gate, can be fabricated and installed.

Pedestrians can use the east gate walkway but won’t be allowed to cross using the west gates until the railing is replaced in about a month.
