US Coast Guard District 8 published an MSIB on the IHNC lock closure and the impacts on ITVs with COIs issued for Rivers Routes.
Effective 08/31/2020 and continuing for approximately for 60 days the IHNC will be closed to all marine traffic due to dewatering operations, repairs, and maintenance. For the duration of the closure an alternate route has been established utilizing the Mississippi River (Alternate Route). The Alternate Route will be completed by transiting via the Baptiste Collette Bayou Channel, through Breton and Chandeleur Sounds, as well as to and from the eastern reaches of the GIWW near its intersection with the Gulfport Ship Channel.
The USCG has made arrangements for vessels subject to 46 CFR Subchapter M that normally operate on Rivers routes (less than 3 nautical miles from shore) as indicated in the MSIB.

On 03/27/2020 the USCG published MSIB Number: 11-20 Maintaining Maritime Commerce and Identification of Essential Maritime Critical Infrastructure Workers
The uninterrupted flow of commerce on our Marine
Transportation System (MTS) is critical to both National Security and economic
vitality. During the ongoing national emergency, it is paramount that we
safeguard the continued operation of the MTS in the face of the acute and
evolving threats posed by the COVID-19 pandemic. The MTS, which provides more
than 90 percent of the domestic supply chain, is dependent on an extensive
support network comprised of workers from both the private and public sectors.
On March 19, 2020, the Cybersecurity and Infrastructure
Security Agency (CISA), within the Department of Homeland Security (DHS),
issued a memorandum that developed an initial list of “Essential Critical
Infrastructure Workers” to help State and local officials as they work to
protect their communities while ensuring continuity of functions critical to
public health and safety, as well as economic and national security (The most
current version can be found:
CISA memorandum and this MSIB are advisory in nature and quarantine orders and
their enforcement are ultimately up to State and local officials. This MSIB
should be used to provide further clarification when making determinations
regarding which MTS workers are considered essential in regions impacted by
COVID-19 quarantine and shelter-in-place orders.
