Earthjustice’s civil rights complaint says the working-class neighborhood has coped for 50 years with the freeway’s original construction. Now it would bear the brunt of new negative effects on residents’ health, quality of life and economic well-being, since dozens would have to relocate. The complaint says the disproportionate impact would violate Title VI of the Civil Rights Act of 1964 because CDOT likely will receive federal funding for the project.
