Canyon, and was extended southeast from Woodland along Sign Route 16 to Sacramento and then south and west via Antioch to the San Francisco – Oakland Bay Bridge approach in Berkeley. The California Freeway and Expressway System was formed in 1959, and included in the planned upgrades was the road between Antioch and Rio Vista. (North of Rio Vista the present SR 84 was part of the system.) The entire length was included in the State Scenic Highway System in 1963. In the 1964 renumbering, the Antioch-Sacramento roadway was split between two routes: Route 84 from Antioch to SR 12 near Rio Vista, and Route 160 from SR 12 to Sacramento. However, the entire route was marked as SR 160, and in 1981 the legislative definition was changed to reflect this. The part of SR 160 through and north of downtown Sacramento began as part of Legislative Route 3, which was added to the state highway system under the first bond issue, passed in 1910, and left the city on the 16th Street Bridge over the American River, following Del Paso Boulevard, El Camino Avenue, and Auburn Boulevard to Roseville. (The short piece from the end of Route 3 near the State Capitol south to Broadway and Freeport Boulevard was Route 4, which followed SR 99 towards Los Angeles.) Route 3 between Sacramento and Roseville was also part of the Victory Highway, and was marked as part of US 40 in 1928 and US 99E in 1929. The North Sacramento Freeway opened on October 6, 1947, bypassing this route from the bridge to Auburn Boulevard near Ben Ali. In 1955, the Elvas Freeway opened from the midpoint of the North Sacramento Freeway to the east side of downtown, and US 99E was moved off the south half of the older North Sacramento Freeway and onto the Elvas Freeway. The North Sacramento Freeway was included in the California Freeway and Expressway System when it was created in 1959, and the part of Route 3 southwest of the Elvas Freeway, which carried I-80, became part of SR 160 in the 1964 renumbering. By 2000, the city of Sacramento maintained the non-freeway portion of SR 160 within the city limits under a contract with Caltrans. However, since Caltrans's main goal is to move traffic efficiently, the city was not able to carry out pedestrian-friendly projects that they and local residents wanted. Under a
