From agrarian fields to a sprawling metropolis, these four murals portray the development of Los Angeles’s transportation systems. A lone train travels toward the city in Circa 1870, while Circa 1910 shows Los Angeles’s massive western expansion 40 years later. The famed four-level freeway interchange and busy downtown streets are represented in Circa 1960, and After 2000 imagines the city’s future with LA Union Station in the foreground surrounded by skyscrapers and a complicated transit network.
