White suburbanites blocked mass transit to keep Black urban residents out of their counties

Evidence

As the new suburbs ballooned in size, traffic along the poorly placed highways became worse and worse. The obvious solution was mass transit—buses, light rail, and trains that would more efficiently link the suburbs and the city—but that, too, faced opposition, largely for racial reasons. The white suburbanites had purposefully left African Americans behind in the central city and worried that mass transit would bring them back. — Nikole Hannah-Jones et al., The 1619 Project, 1202

Categorization

• ADDENDUM: Directly extends the ‘infrastructure as separation’ theme: highways (Grafting & Growth is about infrastructure-as-worldbuilding, but this is the racialized negative face of infrastructure). More precisely connects to how infrastructure choices encode exclusion.
