|1927-47, http://maps.isgs.illinois.edu/ilhap/, the left side is the south side|
John Weeks III has drive-over views and views from the canal (south) side.
This is the first span from the Marseilles (north) side.
And the remaining spans that can be seen from the north riverbank.
In the following view that is taken from further downstream, note that the dam has seven gates closed. The picture after that shows that the eighth gate is about half open on July 10.
A comparable view of the river and bridge that I took on June 27.
I think the "waves" in the June 27th picture are from water turbulence caused by the heavy river flow whereas the "waves" in the July 10th picture are probably caused by the water hitting rocks in the river bottom. That is, the depth of the river on the 10th was low enough that the rough surface of the rapids is being exposed. I'll have to visit again during a dry season to take another look at the river bottom. The flow on July 10th was about 8 kcfs. I did not discover the flow data until the oldest available value was June 29. And it was 25.1 kcfs.
And for completeness, the underside bracing.
