"This modern structure replaces three old wicket-type dams which served river traffic for over 70 years. Several full-size wickets and a workboat, used to operate them, are displayed at the visitor center." [CorpsLakes]

The pin for the sector gear for each of the four gates of the auxiliary lock were replaced starting Nov 16, 2020. This was in preparation for repairing the main lock in 2021 and 2022.

Our aging infrastructure, which includes our critical locks & dam system,on the inland waterways is under the watchful eye of the United States Army Corps of Engineers. 

Currently, one such lock, Hannibal, at Mile 126 on the Ohio River is under repair. 

Here we see the U.S. Army Corps of Engineers, Headquarters towboat M/V EVANICK and crane Barge HENRY M. SHREVE. This flotilla with superstructure and equipment was caught near Ravenswood, West Virginia en route to Hannibal Locks. 

Now this is a wonderful example of our tax dollars at work keeping our nations cargo moving and our economy humming along!

Some great pics of one of our 3 regional repair fleet units traveling to the next lock for the next major maintenance job! These are some big jobs that require big equipment with heavy lift capacity cranes & derrick boats. Highly skilled trades workers with specialized skills of all kinds make up these crews. Amazing capabilities!

[Not only did they place the building on a mound of dirt, I presume they installed the concrete barriers to keep floating debris away from the building.]
