The Southern California freeways are a vast network of interconnected freeways in the megaregion of Southern California, serving a population of 23 million people. The Master Plan of Metropolitan Los Angeles Freeways was adopted by the Regional Planning Commission in 1947 and construction began in the early 1950s. The plan hit opposition and funding limitations in the 1970s, and by 2004, only some 61% of the original planned network had been completed.

The western segment is signed as Interstate 210 (I-210) from its western end at I-5 to SR 57 in Glendora, while the eastern segment is signed as State Route 210 (SR 210) to its eastern terminus at I-10.

The main portion of the existing route begins at Vista Del Mar in Los Angeles near the Los Angeles International Airport and ends at the Anaheim–Orange city line at Via Escola where it becomes Cannon Street. Historically, the Imperial Highway extended from Vista Del Mar to Calexico, where a portion of the highway still exists. The original route was replaced with other highways, leading the older portions of the Imperial Highway to fall out of use.

Many of the existing freeways in Southern California's Inland Empire were completed in the late 1970s. The only exception is the segment of the Foothill Freeway, State Route 210 between San Dimas and San Bernardino, completed in July 2007. In general, most of the higher paying jobs are located in Los Angeles and Orange County. Thus, workers must commute daily up to two hours in each direction on the existing network. As the population increases, traffic congestion is also projected to increase. In 2007, Forbes magazine ranked the area first in its list of America's most unhealthy commutes, beating every other major metropolitan area in the country, as Inland area drivers breathe the unhealthiest air and have the highest rate of fatal auto accidents per capita.
Highway revolts have occurred in cities and regions across the United States. In many cities, there remain unused highways, abruptly terminating freeway alignments, and short stretches of freeway in the middle of nowhere, all of which are evidence of larger projects which were never completed. In some instances, freeway revolts have led to the eventual removal or relocation of freeways that had been built.
