The Joe Hardin Lock (No. 3) NM 50.2 closure detail that was previously noted in Nav Notice SWL 23-28 has been revised. The lock will now be closed to traffic beginning at 7 a.m. on September 11, 2023, until 7 p.m. on September 15, 2023. This is to allow workers to upgrade the lock interlock system which is an integral safety function of the Lock.
