In 1956, Congress passed the Federal Aid Highway Act, authorizing the construction of 41,000 miles of interstate highway. The program was sold as a defense measure — the highways would allow for rapid military mobilization in the event of a Soviet attack — but its primary effect was domestic. It reorganized American cities more thoroughly than any other single policy in the country's history.
In Miami, I-395 cut through the heart of the Overtown neighborhood, destroying hundreds of homes and businesses and displacing a community that had been the center of the city's Caribbean and Latin American immigrant life for decades. The story is not unique to Miami. Across the country, the interstate highway program was routed through low-income and minority neighborhoods, which had less political power to resist.
The Displacement Pattern
The pattern was consistent enough to be a policy. Highway planners in the 1950s and 1960s were explicit about using highway construction to clear what they called 'blighted' neighborhoods — a term that, in practice, meant neighborhoods where Black and immigrant communities lived. The highways served a dual purpose: they moved cars, and they removed people.
The highways served a dual purpose: they moved cars, and they removed people.
The long-term consequences are still visible in American cities. The neighborhoods that were bisected or destroyed by highways have, in many cases, never recovered. The communities that were displaced were scattered, their social networks broken, their institutions dispersed. The physical damage to the urban fabric — the noise, the pollution, the barrier effect of a ten-lane highway — persists decades after the construction.
The Reckoning
There is now a serious movement to remove urban highways. Several cities have already done it: San Francisco removed the Embarcadero Freeway after the 1989 earthquake. Milwaukee removed the Park East Freeway in 2002. Seoul removed an elevated highway and restored the stream it had buried. In each case, the removal was followed by neighborhood revitalization, increased property values, and improved quality of life.
Miami is studying the removal of the elevated section of I-395 through downtown. The proposal is serious, the federal funding is available, and the political will appears to be building. Whether it happens will depend on whether the city can hold its nerve against the inevitable opposition from suburban commuters who have organized their lives around the assumption that the highway will always be there.
