Re-Opening of GIWW Alternate Route
Effective immediately on October 31, 2020, the Captain of the Port (COTP) New Orleans has set Port Condition NORMAL for the Gulf Intracoastal Waterway (GIWW) Alternate Route.  Vessel transits are permitted on the Alternate Route (refer to MSIB Vol XX Issue 087a for details).

All Aids to Navigation (ATON) discrepancies were either corrected or temporarily corrected.  The following virtual AIS signals are not being broadcast as a result of damage sustained to Breton/Chandeleur ICW Alternate Route Light 15 (LLNR 957.12):

Mariners are reminded that the IHNC Lock and St. Claude Avenue Bridge are closed.  Mariners using the GIWW Alternate Route should continue to be aware of shoaling found in the vicinity of Buoy 22 (mile 1.7) in Baptiste Collette; refer to https://hydrosurvey.mvn.usace.army.mil/navpgs/n_outlets_at_venice.asp for the updated USACE survey of the area.

The 100-yard radius safety zone around a damaged platform in Breton Sound Block 49 (approximate position 29-27-01N / 089-17-41W) remains in effect (reference LNM 41-20).

Although waterways are open to traffic, shoaling, storm debris, and other hazards may still exist.  Mariners transiting the area should use caution, and report any Aids to Navigation damage or other waterways issues to the Coast Guard.
