Back in January of 2021 we noticed that the owners of Chesterfield Mall were building walls blocking off the old Dillard’s and Sears wings of the mall, which were also the oldest portions. When I went back recently, their plan had been implemented, and those parts had been locked and closed off.
A similar form of triage had been performed at Jamestown Mall in the waning days of its operation, which you can see in this post from October of 2011.
