The urban sprawl of South Sacramento began with the routing of former U.S. Route 99 (now Stockton Boulevard) through the area. Stockton and Franklin boulevards extend southerly from Downtown Sacramento, and were used from the earliest days of the "gold mining" era for land routes to Stockton—as well as to travel to farming areas—long before the route was designated a U.S. highway.

The next transportation growth was the Southern Pacific Railroad and then several years after, the Western Pacific Railroad, both of which railroad tracks in neighboring Florin.

During the 1940s, steady growth of residential areas was occurring in neighboring areas of South Sacramento. During the 1950s additional shopping centers were developed on or near Stockton Boulevard and Florin Road, and new residential areas developed in the nearby Lindale and Florin areas. Rapid growth occurred in the early 1960s as the Florin Mall was built in South Sacramento as well as additions to the Lindale area, tapering off in the late '60s to early '70s.
