The Implications of Freeway Siting in California: An Equity, Geospatial, and Case Study Approach

Project Summary

Project number: PSR-20-40
Funding source: Caltrans
Contract number: 65A0674
Funding amount: $199,414
Performance period: 1/1/2021 to 12/31/2021

Project description

Conducted in parallel between researchers at the University of California, Los Angeles (UCLA) and the University of California, Davis (UC Davis), this multidisciplinary project will examine four consequences of freeway construction on minority neighborhoods: 1) direct disruption, including disinvestment and loss of housing, local businesses, and local institutions, 2) increasing segregation, such as facilitating suburban white flight and hardening of racial boundaries, 3) diminished access to job or education opportunities because of spatial mismatch, and 4) health impacts because of increasing mobile sources of pollution. Freeway siting continues to have profound health, employment, educational, and social consequences decades later, so uncovering its history is vital to addressing one of the state's most significant spatial inequities.
