The Rockford Files Police Station seen in many of the series episodes at De Longpre & Wilcox in Los Angeles - Los Angeles City Police Station

The old Los Angeles Police Station has long been demolished to make room for a brand new modern police station at De Longpre and Wilcox Avenues in Los Angeles.
