QuoteCarmageddon–it was the nightmare scenario L.A.'s transportation authorities warned of when a construction project shut down a critical stretch of freeway for an entire weekend in July 2011. Gridlock. The glow of brake lights. The overwhelming angst of a city denied its full and unimpeded access to its freeways. In the end, the public outreach built around that ominous term worked. Motorists stayed home, and life went on as normal. A few wags even staged a "dinner party" on the deserted freeway.
But it's possible that all the dire warnings and clever pranks obscured a more troubling possibility: that Carmageddon had already come to pass decades ago, in the 1940s, '50s, and '60s, when Los Angeles scarred its landscapes, split its communities, and displaced a quarter-million people to build its 527-mile freeway system.
