The History of Sacramento Freeway Development

This page attempts to give a brief summary of the development of the freeway system in the Sacramento area.

Figure 3. Sacramento Area Excerpt from 1963 State Highway Map

Figure 1 shows a rough planning map for the Sacramento area from the 1950s (I don't have the exact date). The numbers on the map were provided by Joel Windmiller. Figure 3 shows the 1963 State Highway map for Sacramento. Comparing and contrasting these maps, one notices the following:

The planning map shows some additional routes that were not on the 1963 map, either due to the area covered by the map, or for other reasons:

The 1958 Trafficways Map, prepared by De Leuw, Cather, and Company, shows the following freeways and expressways:

Contrast the planning maps with the map in Figure 4, which is the 1994 State Highway inset map for Sacramento:

[1994 Sacramento Inset]
Figure 4. 1994 State Highway Map Inset for Sacramento

This map shows that Route 102, Route 143, Route 148, and Route 65 are undetermined, and unlikely to be built. It shows a new Route 256, which wasn't defined in 1963. Other routes exist (such as Route 84 or Route 275), but are unsigned. Contrasting this with a 2000 map (alas, no longer available), one can see a significant change in Route 102. There was a planned realignment from the Auburn-Folsom-Rio Linda-Elkhorn routing of Route 102 (which would've crossed I-80 twice and paralleled Folsom Lake and Elkhorn Boulevard/Greenback Lane) in 1994 as contrasted to the mid-1990s plan of a direct route from Auburn to Elkhorn/Natomas crossing through undeveloped areas in Sacramento and Placer County.
