There should be some towboat traffic backups at the Greenup Locks and Dam this summer when the main lock is shut down for 13 weeks to replace the upper gates, the miter and the quion blocks. I know what the miter gates are, but the others, no. There should be some good opportunities to get photos of boats along the banks waiting their turn to double-lock through Greenup. Work begins June 4 and is to be completed by the end of August.
Then the small lock at Robert C. Byrd is scheduled to be out for 16 weeks immediately after that for repairs that will require the lock to be dewatered. The impacts on navigation probably won't be so much, though.
