Corps advises mariners of Charleroi single-lock chamber closure

 

PITTSBURGH -- The U.S. Army Corps of Engineers Pittsburgh District is alerting marines that scheduled repairs at Monongahela River Lock and Dam 4 at Charleroi will close the river to navigation from 12 a.m., May 15 through 11:59 p.m., June 16. 

The repair fleet will be working on the facility’s 56-foot by 720-foot chamber land and corner walls. However, the Corps will open the single-land chamber for restricted operations during the following four weekends.

RESTRICTED OPERATIONS:

May 20 through May 21 – The single land chamber will be open to navigation traffic with no restrictions.

May 27 through May 29 – The single land chamber will be closed to navigation traffic.

June 3 through June 4 – The single land chamber will be open to navigation traffic with a width restriction of 35 feet and a length restriction of 300 feet.

June 10 through June 11 – The land chamber will be open to navigation traffic with a width restriction of 35 feet and a length restriction of 300 feet.

PROCEDURES: The Self-Help Program will be in effect for up-bound and down-bound commercial traffic. All vessels must moor on the land wall while in the lock chamber. Vessels will be directed where to tie off; two lock lines will be required. All vessels are to remain clear of the middle wall at all times. The new upper and lower river guide walls will be available for vessel mooring.

Due to the limited lockage times, towboats are advised that not answering a call from the locks will result in being dropped to the end of the waiting list.

There will be no change to the lockage procedures for recreational boaters during this closure.

Mariners are advised to monitor marine radio Channel 13 for additional information.

The Pittsburgh District’s 23 locks and dams on the upper Ohio, Monongahela and Allegheny rivers represent the oldest and largest network of navigation facilities in the Army Corps’ national inland marine transportation system.
