1953 Highway Madness In L.A.
Los Angeles is widely known for its traffic and smog, miles of freeway stretching in every direction--the ultimate automobile city. Indeed, its highway system is one of the most extensive in the nation, famous for its criss-crossing interchanges. The first of these interchanges, the world's first four-level interchange structure, was opened on this day. The massive concrete structure connected the freeways of Hollywood, Harbor, Santa Ana, and Arroyo Seco.
