Freeway Construction Was the Real Carmageddon for L.A.'s Communities

After a weekend in which Los Angeles successfully navigated the closure of one of its most clogged freeways once again, we look back at the disastrous effect that freeway construction had on L.A.'s communities during the middle of the last century.

Carmageddon II went off without a hitch this past weekend, as Angelenos easily adjusted their schedules and transportation plans to avoid the closure of a crucial stretch of the San Diego Freeway and celebrated their local communities. However, for three decades in the middle of the last century, and with repercussions ever since, the process by which the Santa Monica Freeway was planned and constructed tore apart L.A.'s neighborhoods. Nathan Masters traces the planning and construction of the I-10 Freeway, "an indelible marker across the Los
Angeles landscape, a mini-equator that delineates boundaries between
cultural and historical hemispheres of the city," segregating the affluent north of the city from the disadvantaged south. 

Constructed as part of L.A.'s second generation of freeways, the I-10 was built as "part of a broader statewide and national effort."

"With this backing," says Masters, "came bolder plans and a tendency to subordinate local
concerns to the needs of the larger region. Mapping their proposed
routes, planners drew lines straight through established residential
communities. Houses and local businesses along the route were no more an
obstacle than existing surface streets or water mains; the state would
purchase whatever property it needed, relocate residents, and
reconfigure the neighborhoods around the new freeway."
