message: A recent edit says dam #27 was built to keep the water level high enough at the low end of the old lock #26.  This article, which names no sources, says it's to keep the pool high enough upstream of lock #27.  The dates don't match up either: 1953 vs. 1960.  Could it be that the dam was built along with the canal & locks #27 in 1953, but hightened somewhat in 1960?  (It' can't have been heightened too much!)  I searched "dam 27" on .mil sites to find what the Corps of Engineers might have on it, but I didn't find much.  These are the kinds of things that need to be cited.  --Kbh3rdtalk 21:49, 17 July 2007 (UTC)
replies: text: A couple notes, Survey number HAER IL-33 data page 3 says dam 27 was constructed in the early 1960s and provides additional depth for more efficient operation of #26, the old Alton lock and dam. It has 92 images in it and 11 data pages to explain the facility and its historical context. The Alton lock and dam apparently was problematic since its construction, maybe the dam was an attempt to save it or something. Eventually the Alton facility was replaced by Melvin Price Locks and Dam and was destroyed. We have an article about the Chain of Rocks Lock (#27) but no article focuses on the dam at this time. Most of the other L&D articles include the lock and dam in the stub article, but that one must not include the dam because of the distance between the two facilities and possibly the simplicity of the dam. See also List of locks and dams of the Upper Mississippi River for others. As for the 1953 date, I assume that means the date of the opening of Lock 27, February 1953, per HAER IL-33. --Dual Freq 23:04, 17 July 2007 (UTC)

message: There is a glaring discrepancy between this article and the article New Chain of Rocks Bridge.
In this article, it is stated:
:"Its most notable feature is a 22-degree bend occurring at the middle of the crossing, necessary to allow river traffic to have uninterrupted navigation on the river."
However, in the New Chain of Rocks Bridge article it is stated:
:"The original Chain of Rocks Bridge was a narrow bridge with a 22 degree bend midway over the river... The true reason that the 22 degree bend existed was to minimize construction costs, as a placing a bend in the bridge was the only way to ensure the bridge was consistently laid upon bedrock."
Well which is it? here I find:
:"The promoters had purchased land on each side of the river, but the parcels were not directly across the river from each other. The plan was to build the bridge on a diagonal to the river. The US Army Corps of Engineers objected to having a bridge cross the navigation channel at an angle. As a result, the section of the bridge crossing the navigation channel was built straight across the river, and then the remaining part of the bridge was built on the diagonal to meet up with the Missouri shore. The result is the 24 degree bend where the straight and diagonal sections meet."
which tends to support the former explanation, but not exactly, and actually seems to be a third explanation. Plus who is John Weks anyway? And why does a bridge crossing a river diagonally impede navigation? This official Missouri document (pdf) states that both reasons are in play. So this seems rather murky at best, and if a truly reliable original source can't be found, perhaps we should remove speculation about the reason for the 22 degree bend from both articles. 
I am cross-posting this at the New Chain of Rocks Bridge talk page. Herostratus (talk) 03:57, 25 March 2010 (UTC)

message: Is this the same bridge used in Escape from New York?  Trivia on IMDB notes that John Carpenter, the director, purchased this bridge from the City of St. Louis for $1 then returned it to the city for the same amount after filming.

message: It states that there is a 22-degree bend in the middle of the bridge but then there is no reason given for why this design decision was made. Was it economics? Practical reasons? Or geological? Kind of a glaring omission for such a historical and noteworthy structure. 146.200.202.126 (talk) 10:45, 17 July 2022 (UTC)
