their tax monies to building highways—including Hwy 13, commissioned in 1947, and named for US Supreme Court Justice Earl Warren; and Hwy 580, completed in the 1960s, and named for General Douglas MacArthur. The removal in the 1950s of Oakland's streetcar lines (known as the Key System), the resulting dominance of car culture, the swiftness of transportation, and the increased density of housing stock have all dramatically changed the ecology and sociology of Redwood Heights. Today, the community organization based in the area is called Redwood Heights Association. Its focus is on Bringing People Together, and it is dedicated to substantially improving the quality of life for Oakland residents by hosting community events and spearheading capital improvement projects. Historical articles about the area are available on the Redwood Heights Association website. References External links Redwood Heights Neighborhood Association Neighborhoods in Oakland, California
