The Corridor, Teralta West, and Teralta East are linear neighborhoods located in the middle strip of the Mid-City plateau. They were originally developed with single-family housing as the suburban addition to San Diego, and located along the east trolley corridor and the original Highway 80 (El Cajon Boulevard) route. The area has been developing since World War II with higher-density apartments and condominium development.
These neighborhoods now contain the highest population density in Mid-City. Much of the housing is multifamily combined with older single-family development and some older apartment courts.
Commercial needs are served by The Boulevard and University Avenue commercial corridors. All residences are within a walking radius of commercial services.
