context: The Santa Monica Freeway (Interstate 10) begins in Santa Monica near the Pacific Ocean and heads east. The Santa Monica Freeway between Santa Monica and downtown Los Angeles has the distinction of being one of the busiest highways in all of North America. After traversing Los Angeles County, I-10 crosses seven more states, terminating at Jacksonville, Florida. In Santa Monica, there is a road sign designating this route as the Christopher Columbus Transcontinental Highway. State Route 2 (Santa Monica Boulevard) begins in Santa Monica, barely grazing State Route 1 at Lincoln Boulevard, and continues northeast across Los Angeles County, through the Angeles National Forest, crossing the San Gabriel Mountains as the Angeles Crest Highway, ending in Wrightwood. Santa Monica is also the western (Pacific) terminus of historic U.S. Route 66. Close to the eastern boundary of Santa Monica, Sepulveda Boulevard reaches from Long Beach at the south, to the northern end of the San Fernando Valley. Just east of Santa Monica is Interstate 405, the "San Diego Freeway", a major north-south route in Los Angeles County and Orange County, California.
