Los Angeles Mayor Antonio Villaraigosa speaks at a news conference to announce the Mulholland Drive bridge over Interstate 405, which crosses the Santa Monica Mountains connecting the San Fernando Valley and the Westside of Los Angeles, is seen Monday, June 6, 2011. Los Angeles authorities are bracing for a full-blown traffic nightmare when a section of vital route undergoes a weekend closure this summer. Los Angeles County Supervisor Zev Yaroslavsky said motorists should stay away from the area to prevent what he terms "car-mageddon." A 10-mile stretch of the 405 through Sepulveda Pass will be closed for 53 hours for demolition of half of the bridge in mid-July. (AP Photo/Reed Saxon) less
