These are notes that I am writing to help me learn our industrial history. They are my best understanding, but that does not mean they are a correct understanding.

Mississippi Lock and Dam #5A at Minnesota City, MN
USACE-mission - Constructed 1932, placed in operation in 1936. Last major rehabilitation 1989 through 2000. - Dam consists of a concrete structure 682 feet long with five roller gates and five tainter gates. Earth embankment 22,000 feet long. - Concrete overflow spillway 1,000 feet long. USACE-content A lift of 5.5' This site is closed to the public.
In addition to providing two spare gates, the Rock Island District also loaned their Hercules 60' ringer platform barge that David Pickett caught going through L&D #18.

David Pickett posted three photos with the comment: "Corp of Engineers crane, The Hercules. We're eliminating lock gates." Levi Kriete350 tons over the stern at a 70’ radius.
The title used to say the dam was at Winona, MN, even though references put it at Minnesota City, MN, or Fountain City, MN. After discovering L&D #5, I now understand why they don't use Winona. Namely, there are two dams within a few miles of each other near Winona.
Angle Binnar shared USACE's post We will have four temporary closure periods at Lock and Dam 5A near Fountain City, Wisconsin, from 7 a.m. to 7 p.m., July 19, 21, 26 and 28, to replace the lock chamber’s [90-year old] miter gates.

Re: Hercules: The Hercules was initially purchased by Melborne Bros. Construcion of North Canton, Ohio. The crane and the barge was designed specifically to erect the bridge in Luling. The main barge has 4 outrigger barges with concrete counterweights. These barges provide stability, but they also allow for transportation on the river. The barges are detached and set on the main barge to make the Hercules narrow enough to pass through the locks. After completing the bridge in Luling, Melborne Bros took their crane to Huntington Ohio to erect another cable stayed suspension bridge. The 2-lane bridge in Huntington had precast concrete deck sections that were lifted into place. Both bridges and the crane were on the cover of Engineering News Record. I believe the Huntington bridge was completed in 1984. The crane was sold after the Huntington bridge was completed. At that time, Hercules has erected 2 of the first 4 cable stayed bridges in the US. I was on board the Hercules once when it was in Huntington. It was impressive enough for me to look it up on line today and leave this information.
Thanks for the information. I have copied this comment to my Hercules notes: https://industrialscenery.blogspot.com/2017/06/60-foot-ringer-crane-in-1980s.html My notes indicated that the next bridge built by this crane was Arthur J Ravenel Jr. Bridge (https://industrialscenery.blogspot.com/2017/04/us-17-over-cooper-river-in-charleston.html). Since that bridge wasn't built until 2005, that can't be true. So I have removed that statement.
