Today’s Key Issues

  • Montgomery Lock and Dam (OR31.7) Main Chamber will be closed 7/26/21 thru 8/27/21. Boat will have to use Auxiliary Chamber to navigate lock. Expect delays if you have barges moving through this area.
  • Olmsted Locks and Dam (OR 965)Effective 26 July 2021, project personnel will begin raising the wickets to hold pool due to lower water levels. Navigation traffic is moved to the lock chambers.
  • Revetment Operation Update at LM 933 – As of Friday 7/23, USACE and Industry were able to establish measures to permit one-way NBD and SBD transit through this area during working hours. Expect up to 6-hrs of delay through conclusion of this work by the end of July. The operation will then move to Barfield at LM 807 with a potential for delays TBD.
  • West Canal Closure – Lifting Mechanism failure on the Belle Chasse Bridge has closed the West Canal at WC 3 since 7/21 through 7/25. The air-draft clearance of the bridge is 40′, vessels below this height were able to transit this area. This issue increased traffic along the Port Allen route and may result in 2-4 days of delay to shipments moving between Houston and NOLA.
  • David Terry Lock Closure (AK 108) – Repairs are scheduled to fully close David Terry Lock for two weeks just below Little Rock 8/27 – 9/9. Prior to this, the lock will see intermittent closures 8/16 – 8/26. This will effectively close-off access to the Ark from the LM. For our latest commercial guidance, please click here.
  • Warrior-Tom Closure for Lock Repairs – Maintenance will close the Warrior-Tom at Bankhead and Oliver Locks 6/24 through 7/23. This is a full 30-day closure which will cut-off access to Birmingham and Tuscaloosa.
