Caltrans Freeway Plans for the Bay Area
In the 1950’s and 1960’s traffic engineers ran wild with plans for urban freeways in the United States. The general consensus was that freeways had no downsides and were not visual blights, pollution emitters, and neighborhood dividers. Even as the public mood changed against freeways in the 1970’s and 1980’s, State Departments of Transportation continued to try to follow through with their grandiose plans for urban freeways.
This map shows plans for urban freeways in the San Francisco Bay Area. I was inspired to create this map when I saw several proposed freeway maps created by Caltrans from 1945 to 1986. These maps made me think of the vast changes in the geography of the area that these freeways would have created. CA 93 along San Pablo Dam Road would have ramped up suburban development around Tilden Regional Park, a Bay Area wilderness treasure, and CA 77, CA 13 and CA 61 would tear through the urban fabric of Oakland. Note that most of the freeways proposed in San Francisco were defeated early, in 1959, by the Freeway Revolts. I hope this map makes you think about the massive changes new freeways can make in undeveloped areas and inspire you to oppose the continuation of the 20th century pattern of wilderness-freeway-sprawl.
