The USCG has updated the safety measures in place for the revetment operations.

Key Change

—————————

The revetment operations will be conducted daily from 5:00 A.M. – 4:00 P.M. local time through December 18, 2019, including the weekend. During times of actual revetment work, the Mat Sinking Unit (MSU) will extend approximately 300-800’ channel ward from the bank. The platform will be removed from the channel within 2 hours of work ending and the channel will have no restrictions at night.
