In the greater Los Angeles area, it is known as the Santa Monica Freeway and the San Bernardino Freeway, linked by a short concurrency on Interstate 5 (the Golden State Freeway) at the East Los Angeles Interchange. Interstate 10 also has portions designated as either the Rosa Parks Freeway or the Redlands Freeway. ==Route description== The California Streets and Highways Code defines Route 10 from "(a) Route 1 in Santa Monica to Route 5 near Seventh Street in Los Angeles. (b) Route 101 near Mission Road in Los Angeles to the Arizona state line at the Colorado River via the vicinity of Monterey Park, Pomona, Colton, Indio, and Chiriaco Summit and via Blythe.." Despite the legislative definition, Caltrans connects the two sections of the route by cosigning I-10 down Interstate 5 between the East LA Interchange and the Santa Monica Freeway, negating a section of the San Bernardino Freeway west of I-5. This short section of Route 10 between Route 5 and Route 101, which was formerly defined as Route 110 (signed as Interstate 110) until 1968, is signed overhead for I-10 eastbound and for U.S. 101 westbound. I-10 is part of the California Freeway and Expressway System and is eligible for the State Scenic Highway System. However, it is not actually a scenic highway as designated by Caltrans. The Santa Monica Freeway is Route 10 from Route 1 to Route 5, as named by the State Highway Commission on April 25, 1957. The section between the Harbor and San Diego freeways is also signed as the Rosa Parks Freeway. This freeway is signed as the Christopher Columbus Transcontinental Highway in Santa Monica. The Rosa Parks Freeway is Route 10 from Route 110 to Route 405, as named by Assembly Concurrent Resolution 134, Chapter 2 in 2002. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Interstate 10 in California」の詳細全文を読む スポンサード リンク
