PORTLAND — The $23 billion of commerce that flows along the Columbia River will pause for two weeks, beginning March 2, 2024, as the U.S. Army Corps of Engineers (USACE) Portland District closes three navigation locks for annual inspections and maintenance.

The closure will include annual inspections and routine maintenance, as well as additional rappel inspections at John Day by a USACE climbing team, according to a USACE press release.
