The Public Works department in Alton is getting ready to put a concrete wall in place again to protect downtown Alton. This time, the city is expecting the Mississippi River to be about the same or maybe slightly higher than it was earlier this month, as more rounds of heavy rain are coming downriver from the Upper Midwest.

Public Works Director Bob Barnhart tells The Big Z while it's expected to be a quick rise and quick fall, he's taking nothing for granted.

At the new forecast height, he says some of the infrastructure at the Liberty Bank Alton Amphitheater may be flooded, so they are making plans to ether protect it or move it before the river takes over.
