Ballard Locks repair to disrupt vessel, visitor traffic

Repair work on an eroded portion of the small lock wall at Hiram M. Chittenden Locks is expected to close the locks for several days at the end of January, according to the U.S. Army Corps of Engineers.

A scour hole along the wall was detected in a 2009 sonar survey, and a later dive inspection detected a void under the wall’s foundation. A contractor will drive sheet piles adjacent to the wall, creating a type of armor to prevent further erosion and to serve as a form for concrete that will be pumped in to fill the void.

The work should take about 60 days, and force the closure of the 95-year-old locks for several days, the corps said.
