'Carmageddon 2' fails to be a nightmare [Photos]

A 10-mile stretch of the interstate highway — the most heavily trafficked road in the country — was shut down this weekend as part of a $1 billion freeway improvement project. But "Carmageddon 2" didn't quite live up to the hype.

Although last year's Carmageddon proved to be significantly less apocalyptic than originally predicted, the city made a concerted effort this year to prevent traffic headaches by encouraging Los Angeles residents to limit weekend activities to their own neighborhoods.
