| 摘要： | The Portland Engineer District recently released a video showing some of the work performed during a recent closure of Bonneville Lock on the Columbia River. During the closure, the lock was de-watered, and the Corps performed inspections and maintenance, including a close examination of the downstream miter gates, which are each 95 feet tall and 50 feet wide. The series of locks on the Lower Columbia-including at John Day and The Dalles dams, in addition to Bonneville-are a vital piece of transportation infrastructure. The Corps performs maintenance during scheduled outages, which ensures that these systems stay open on a reliable schedule. To maintain safe and reliable passage through this valuable navigation system, the Corps coordinates the annual lock closures with inland shippers and cruise lines to minimize impacts to those users. |
