The first expansion of the complex (in dark gray) was built in the early 1970s. A second enlargement (medium gray) was done in the mid-1980s. It added a 2-level West Wing, parking garage and J.C. Penney anchor store.

Here we see the Upper Level mall concourse, which was a part of the original -circa-1964- SHOPPING PARK.
