In 'City Limits,' Kimble exposes how U.S. interstate construction was deliberately routed through Black and Hispanic neighborhoods in mid-20th-century Texas—displacing residents, worsening pollution, and entrenching health and economic disparities. She reveals that federal officials knew early on highways wouldn’t solve congestion and that transit offered a better alternative, yet political interests prioritized road-building anyway. Drawing on three Texas case studies, she shows how $65 billion continues to fund destructive expansions instead of equitable alternatives. Through intimate portraits—like a preschool pressured to accept pennies for relocation and Modesty Cooper’s home threatened by I-45—Kimble humanizes systemic harm while spotlighting grassroots resistance: youth-led ballot initiatives, civil rights lawsuits, and community organizing that have successfully paused or reshaped projects. Her work reframes highways not as neutral infrastructure but as deliberate policy choices with profound racial, environmental, and democratic consequences—challenging the myth of inevitability and insisting on accountability, imagination, and justice in urban planning.
