@KFuentesGeorge In my town, Vallejo California, they straight up bulldozed half of downtown for a freeway that never came.
Vallejo was a Navy town, and had a huge, rather seedy nightlife spot for the sailors on leave. Party town of the west coast. During WWII a large number of black Americans were brought in to work the shipyard, in segregated housing. Like most of the Bay Area there hadn't been much of a black population before WWII.
Within 15 years of the war ending white flight had taken over and they simply bulldozed most of downtown to stop any black owned businesses from forming in the vacuum. Highly restricted zoning to prevent even restaurants. It was repeated all over the Bay Area - Oakland, Richmond Hunters Point, Marin City. Any place that had ship building intentionally sabotaged the economic growth of the city long term because of the demographic changes, to prevent black wealth.
Pisses me off on so many levels.
