Urbanist Argues Against Highways

The core argument of Strong Towns centers on what founder Chuck Marohn, a former civil engineer and planner, calls the "Growth Ponzi Scheme." This theory posits that the initial wave of new suburban development brings a short-term cash infusion to cities from fees and new taxes, but it creates long-term, unsustainable maintenance liabilities for infrastructure like roads and pipes. This model of horizontal expansion often results in a low tax yield per acre compared to more compact, traditional development. Studies have shown that walkable urban areas, which constitute only 1.2% of the land in the largest 35 U.S. metropolitan areas, generate 20% of the country's GDP. Furthermore, real estate in these walkable places can command a 35-45% price premium over car-dependent suburban areas. Historically, the construction of urban highways, particularly after World War II, displaced an estimated one million people and often deliberately sliced through and isolated minority neighborhoods. In Miami, for example, highway construction wiped out 40 square blocks, including a prominent Black business district and around 10,000 homes. These projects have been linked to lasting social divisions, reduced community connectivity, and negative health impacts from pollution. A growing number of cities are reversing these decades-old infrastructure decisions by removing urban highways. In Rochester, New York, the removal of a portion of the I-490 Inner Loop cost $22 million but has spurred $229 million in private investment. The project opened up 6.5 acres of land for development and led to a 50% increase in walking and a 60% increase in biking in the area. Other cities have seen similar revitalization. After San Francisco's Embarcadero Freeway was damaged in the 1989 Loma Prieta earthquake and subsequently demolished, the area was transformed with a waterfront promenade and public plaza. In Milwaukee, the removal of the Park East Freeway spur cost $25 million—less than the estimated $50-$80 million to repair it—and opened up valuable downtown land for new development. The Strong Towns approach has faced criticism for what some see as a deeply conservative, austerity-minded ideology that focuses on financial solvency above all else. Critics argue that the philosophy can oversimplify complex historical and political reasons for urban development patterns and may not adequately address issues of social equity. Despite critiques, the movement has influenced numerous local policy changes. Cities like Chicago and Dallas have slashed parking mandates to encourage more affordable housing and business development. Other communities are using "tactical urbanism"—small-scale, low-cost interventions like DIY crosswalks and pop-up shops—to demonstrate the potential for more people-oriented street designs.
