The Sixth Street Viaduct, also known as the Sixth Street Bridge, is a viaduct bridge that connects the Arts District in Downtown Los Angeles with the Boyle Heights neighborhood.

The Arts District is a neighborhood on the eastern edge of Downtown Los Angeles, California in the United States. The city community planning boundaries are Alameda Street on the west which blends into Little Tokyo, First Street on the north, the Los Angeles River to the east, and Violet Street on the south. Largely composed of industrial buildings dating from the early 20th century, the area has recently been revitalized, and its street scene slowly developed in the early 21st century. New art galleries have increased recognition of the area amidst the downtown, which is known for its art museums.
