Study Notes
Freeway Rerouting and Environmental Justice
- Freeway rerouting and replacement with boulevards can reduce air pollution, but may lead to environmental gentrification.
- The study investigates the impact of freeway rerouting on air pollution and neighborhood changes in West Oakland.
- The Cypress Freeway was rerouted and replaced with Mandela Parkway, a street-level boulevard.
- Rerouting the freeway significantly reduced NOx (−38% ± 4%) and BC (−25% ± 2%) concentrations along Mandela Parkway.
- However, there's evidence of environmental gentrification, with a larger decrease in the Black population (−28%) and significant increase in property values (184%) along Mandela Parkway.
- Despite the gentrification, affordable housing along Mandela Parkway allows some low-income residents to live near the boulevard.
