By the mid-1970s, the eastern strip complex was being promoted as the OXNARD TWIN SHOPPING CENTER. The west facility was known as TWIN CENTERS MALL. A renovation of the latter got underway in March 1979. In this photo, and the one that follows, we see the mall in the throes of heavy construction.

The remodeling enclosed the open-air shopping concourse between the east and west store blocks and added terrazzo flooring.
