“Inner Harbor Navigation Canal (IHNC) Lock mariners are advised that the mooring bits located in the long guidewall on the canal end of the Inner Harbor Navigation Canal (IHNC) Lock are very unstable; you may use the wall to line up on when locking but DO NOT tie off on the mooring bits.”
The USACE continues with construction and repair activities at the IHNC Lock that includes periods of hot work (welding) and continues to operate with the conditions listed below:
“Inner Harbor Navigation Canal (IHNC) Lock mariners are advised that there is on-going construction, which includes hot work, at the forebay and tail bay of the Inner Harbor Navigation Canal (IHNC) Lock. Vessels shall adhere to the following:
- Use extreme caution when entering and exiting the lock especially in the vicinity of the construction and keeping a safe distance from the construction.
