United States Interstate Highway System
In reviewThe Interstate Highway System was built with the labor, tax dollars, and expertise of Black Americans, even as its routing was used as a tool to cut through, displace, and devalue Black neighborhoods in dozens of cities. It is both an engineering achievement in which Black workers and professionals participated and a policy instrument deployed to segregate space, drain Black property wealth, and clear Black political bases under the banner of “urban renewal.”
1.Origins and Design of the Interstate System
The Interstate Highway System emerged from mid‑20th century federal planning and defense concerns, codified in the Federal‑Aid Highway Act of 1956 and framed as a national good promising mobility, commerce, and safety. From the outset, route selection was not simply technical but political: decisions about where to place urban segments involved mayors, planning commissions, downtown business interests, and federal officials aligning transportation aims with urban redevelopment agendas. Within this context, Black neighborhoods—often already marked by discriminatory zoning, redlining, and disinvestment—were identified as “blight” zones where land acquisition would encounter the least political resistance.
2.Black Labor and Participation in Highway Construction
Black workers helped build the highways that would later be used to divide their own communities. In many states, Black laborers, equipment operators, and skilled tradespeople worked on road crews, often under segregated job structures and unequal pay scales. Black engineers and planners—though restricted in number by barriers in education and professional licensing—also contributed to transportation design and urban planning, sometimes arguing for routes that minimized harm to existing Black neighborhoods. Their participation illustrates a recurring pattern: Black people are deeply involved in constructing national infrastructure, even when that infrastructure is later turned against their communities.
3.Targeting Black Neighborhoods Under “Urban Renewal”
In practice, urban interstate routes frequently tracked through Black neighborhoods that had already been segregated by earlier policy decisions. City leaders combined federal highway funds with urban renewal powers to clear land labeled “slum” or “blight,” often without serious consideration of alternative routes that would preserve existing Black residential and business districts. In city after city—examples include long‑standing Black communities in New Orleans, Miami, Detroit, and others—highway segments were driven through the heart of Black commercial strips, church corridors, and dense residential areas. The effect was to destroy housing stock, fracture social networks, and strip Black property owners of land under compulsory purchase that rarely compensated long‑term value or community function.
The routing often aligned with existing racial boundaries: planners chose corridors that both served downtown business interests and reinforced segregation by placing physical barriers between Black and white areas. Where Black neighborhoods stood adjacent to central business districts, they were frequently sacrificed as clearance zones, ensuring that wealthier, whiter areas were preserved while Black space bore the brunt of displacement.
4.Displacement, Wealth Loss, and Political Impact
The destruction of Black neighborhoods for highway construction was not only a physical relocation but a large‑scale transfer of wealth and political power. Generations of Black families who had purchased homes despite discriminatory lending practices saw their property condemned, often for compensation that did not reflect replacement costs or future value. Rental communities lost dense social and economic networks—corner stores, barbershops, churches, social clubs—that had functioned as informal safety nets. The fragmentation of Black residential concentrations weakened local political blocs, reducing the ability of Black voters to act as cohesive constituencies in municipal elections.
Because displaced residents were frequently relocated to public housing projects or more peripheral neighborhoods, the highway program reinforced patterns of concentrated poverty and segregation that had been established by earlier federal housing policy. The narrative that highways simply followed “least‑cost routes” obscures the reality that Black communities were repeatedly treated as expendable space in the planning calculus.
5.Resistance, Adaptation, and Later Redress Efforts
Black communities did not accept highway destruction passively. Local activists, homeowners, pastors, and civil rights organizations challenged route decisions through public hearings, protests, and lawsuits, sometimes winning partial concessions, reroutings, or mitigation measures such as sound barriers and redesigned interchanges. In some cities, Black planners and community groups proposed alternative alignments or pushed for investments to rebuild housing and business capacity near new highway corridors.
In later decades, research by Black scholars, investigations by Black newspapers, and community oral histories documented the specific ways highways had targeted Black neighborhoods, reframing the story from neutral modernization to deliberate spatial disenfranchisement. Contemporary movements for highway removal or cap‑and‑deck projects over urban highways often draw on this record, seeking to reclaim land and reconnect Black neighborhoods that were severed. The archive holds these efforts as part of an ongoing struggle to repair damage done by past policy and to assert Black authorship in the future design of urban space.
The archive holds the Interstate Highway System as a central instrument in reshaping American space, wealth, and mobility, with Black people as both builders and primary victims of its routing. The system did not simply pass through Black neighborhoods; it was steered through them as a matter of policy, turning concrete into a weapon against established Black communities. Black resistance to these routes—through organizing, litigation, and alternative planning—marks those communities as authors of urban history, not passive subjects of planning. The record of the highways is incomplete without naming Black labor in their construction and Black sacrifice in the land they took.
