The Cesar Chavez - Macy Street Bridge is first proposed in 1913 by the City Engineer to the Board of Public Works, who recommends his plan despite the construction's damage to Stern's Winery and the Agricultural Chemical Works.

The Fletcher Avenue Bridge is paid for through a bond motion put on the 1924 ballot. In 1926, before its completion in 1927, the Fletcher Street Bridge is slated to be dedicated to the "Empire Builder" known as Jedediah Smith, who crosses the American continent from New Hampshire by way of Salt Lake City, to Southern California.

The cost of building the 7th Street Viaduct is shared with the Los Angeles Railway Company, who operate the trolley system that uses the thoroughfare for its trolleys. The 7th Street Viaduct is initially built in 1910 but undergoes vast improvements. In 1923 traffic on the bridge is so congested that it is estimated that 10,000 vehicles cross it daily and the crossing gates are down for 9 minutes each hour for the trolleys to pass.


Spring Street Viaduct 1928

Upon reaching this area in 1769 Gaspar de Portala describes it as: "a lush spot with tall trees, abundant water and plentiful game." In short, the perfect place to build a pueblo for Spain's colony. The Spring Street Viaduct is built in 1928 and becomes a bypass route acrosss the Los Angeles River for commercial traffic traveling on Santa Fe and Alameda Streets. Today, Farmlab and the Metabolic Studio under the Spring Street Bridge provide creative and provocative talks by artists and researchers interested in land use issues.

Prior to this 1929 bridge, there is a bridge from the 19th century that serves traffic.

Fourth Street Viaduct 1930

The Fourth Street Viaduct is built in 1930 and is noted for its catenary arch, reinforced concrete and complex grade separation. In 1981 an alleged hit and run driver flees his car on the bridge and attempts to escape by jumping from the bridge 75 feet below. He survives with multiple fractures.
Washington Boulevard Bridge 1931

The Bridge is completed in 1931. When building begins on the bridge in 1930, the President of the Washington Bridge Association remarks: "Completion of the bridge will give the East Side Territory a new wide route to the beaches and will aid greatly in relieving traffic conditions."


Sixth Street Viaduct 1932

The Sixth Street Viaduct is vastly expanded in 1932 in part to make a direct connection from Whittier Boulevard to Boyle Avenue, from Stephenson Avenue--to the viaduct.
