"Turning Los Angeles into an Intentionally Segregated City"

"Freeways created physical barriers that made any non-white presence on the 'white' side of the road conspicuous—and thus easier to target by law enforcement. One 1943 freeway marketing pamphlet, designed to win over reluctant white communities, boasted of the freeway's fortress-like impermeability and ability to preserve 'neighborhood character.'
"As Rothstein told NPR in 2017: 'The "Underwriting Manual" of the Federal Housing Administration recommended that highways be a good way to separate African American from white neighborhoods. This... was a matter of government regulation.'"

Matthew Fleischer at the Los Angeles Times discusses how racial segregation was affected by the impact of L.A. freeways.
