The U.S. Army Corps of Engineers Pittsburgh District installed navigation safety signs and buoys upstream and downstream of Monongahela River Locks and Dam 3 near Elizabeth, Pennsylvania, to warn river users and industry of hazardous conditions during the upcoming demolition of a 117-year-old dam.
The district placed the signs on the river 1,500 feet upstream and downstream of the fixed-crest dam. The first dam breach is scheduled for July 10, 2024. The lock chambers will close to navigation at least three days following the initial demolition. The closure may extend up to 12 days depending on river flows conditions.
The work to remove the rest of the dam will continue through December 2024. Until the entire dam is removed, and until the Corps verifies the navigation channel is safe through the area, all traffic must pass through the landside lock. After the initial demolition, contractors will perform additional demolitions once per week, which will require the locks to close for three hours or less.
After the dam is removed and the riverway is cleared, waterway users can navigate through the area without using the lock chambers.
Removing the dam will create a continuous pool of riverway stretching 30 miles, from Charleroi to Braddock, Pennsylvania, improving navigation on the Lower Monongahela River.
