Today’s Key Issues

  • Montgomery Lock and Dam (OR31.7) Main Chamber closed 7/26/21 thru 8/27/21. Boats will have to use Auxiliary Chamber to navigate lock. Expect delays if you have barges moving through this area.
  • Revetment Operation Update at (LM 933) – As of Thursday, 7/29, USCG and USACE have restricted SBD tow size to 9-barge max during working hours. USACE has advised they will not work this weekend. These restrictions will resume 0600 8/2 and expected through completion on 8/6. NBD transit remains permissible during working hours. Expect up to 12-hrs of delay for SBD vessels.
  • Belle Chasse Bridge Construction (WC 3)– LADOT will begin construction activities 8/2 for the removal and replacement of the drawbridge at MM 3 behind Algiers Lock. Transit will see minimal delay during work, aside for intermittent 12-hr closures for work. Accordingly, USACE will keep industry informed of these closures as work progresses, expected throughout 2022. Expect delays to correlate between the intermittent closures and traffic at Algiers during this project. First Closure Period scheduled 0600 – 1900 8/4/2021.
  • David Terry Lock Closure (AK 108) – Repairs scheduled to fully close David Terry Lock for two weeks just below Little Rock 8/27 – 9/9. During this time, Lock will see intermittent closures 8/16 – 8/26. As a result, this closure effectively closes-off access to the Ark from the LM.
