The YORKTOWN mall stayed fairly static between its late 1968 grand opening and the early 2000s, when its first major reconfiguration was done. An aerial view from 2006 shows the south side of the complex in the throes of construction. A vacant Montgomery Ward has been razed and is being replaced with SHOPS ON BUTTERFIELD, an open-air and enclosed lifestyle center.
