Concrete Barriers: The Infrastructural Weaponization of Urban Highway Planning

As the automobile revolutionized the American landscape in the mid-twentieth century, the rapid construction of massive interstate highways was celebrated as the ultimate triumph of modern civic engineering. However, beneath the banner of progress and urban renewal, city planners wielded these towering concrete structures as deliberate, physical weapons of racial segregation. In the rapidly expanding metropolis of Los Angeles, the routing of massive freeways was anything but an objective logistical decision. Politicians and engineers intentionally designed highway grids to obliterate thriving minority neighborhoods, erecting impenetrable walls of asphalt and exhaust that permanently isolated marginalized communities from economic centers, effectively carving structural racism directly into the geography of the city. This powerful historical documentary maps the dark, hidden agendas of 1930s urban planning. It uncovers the archived municipal documents proving malicious intent, chronicles the desperate, ignored protests of displaced citizens, and demonstrates how the physical architecture of the past continues to dictate the economic inequality of the present. Drive beneath the shadows of the modern freeway, and discover the cold, calculated prejudices permanently entombed within the concrete pillars of the American city.
