Here's a picture taken yesterday of the western part of the Quincy Memorial Bridge which takes us from Missouri to Illinois. The water has gone down a bit since yesterday, because this is the one that Al Roker was walking through water on this morning. It's so low that it floods during exceptionally high water and has to be closed. I drove across it Saturday. They are saying now that the crest may have already occurred.
Thankfully, the new bridge is higher and was changed to take traffic both ways when this one closed. There are lots of businesses along the highway on the Missouri side and most have moved out in case the levee breaks as they would be flooded.
