Banham Canyon Drive is a two-way street in Grand Theft Auto V and Grand Theft Auto Online, located in Banham Canyon, Los Santos County that begins at North Rockford Drive and ends at the Great Ocean Highway (Route 1).
Description[]
The use of Banham could be a tribute to English architectural historian Reyner Banham, who studied the architecture and ecology of Los Angeles and published the book Los Angeles: The Architecture of Four Ecologies. Perhaps the Rockstar team used the book as a source material when they studied Los Angeles.
