Interstate 110 and State Route 110 (California) in the context of "Auxiliary Interstate Highway"

The Financial District (Financial Core) is the central business district of Los Angeles. It is bounded by the Harbor Freeway to the west, First Street to the north, Main and Hill Streets to the east, and Olympic Boulevard and 9th Street to the south. It is south of the Bunker Hill district, west of the Historic Core, north of South Park and east of the Harbor Freeway and Central City West. Like Bunker Hill, the Financial District is home to corporate office skyscrapers, hotels and related services as well as banks, law firms, and real estate companies. However, unlike Bunker Hill which was razed and now consists of buildings constructed since the 1960s, it also contains large buildings from the early 20th century, particularly along Seventh Street, once the city's upscale shopping street; the area also includes the 7th and Flower area at the center of the regional Metro rail system, restaurants, bars, and two urban malls.

The Four Level Interchange (officially the Bill Keene Memorial Interchange) is the first stack interchange in the world. Completed in 1949 and fully opened in 1953 at the northern edge of Downtown Los Angeles, California, United States, it connects U.S. Route 101 (Hollywood Freeway and Santa Ana Freeway) to State Route 110 (Harbor Freeway and Arroyo Seco Parkway). In 2006, the interchange was officially renamed in the memory of Los Angeles traffic and weather reporter Bill Keene.
