“IHNC Lock is closed to navigation around the clock, 24hrs per day until approximately 25 November 2020 while the structure is dewatered for major repair work.”
CALCASIEU RIVER SHIP CHANNEL:
The Calcasieu Ship Channel continues to operate with a maximum draft restriction of 36 feet freshwater due to a sunken barge obstruction that is schedule to be salvaged by November 15, 2020.
“There is a 36′ draft restriction on the Calcasieu River Ship Channel until removal of the sunken rock barge, which is on target for 15 Nov or sooner.”
OLD RIVER LOCK:
