Traffic moves along Sepulveda Boulevard as a 10-mile stretch of Interstate 405 is shut down to demolish the Mulholland Drive bridge in Los Angeles, Saturday, July 16, 2011. Traffic in the Los Angeles area is so far moving smoothly, several hours after authorities shut down the 10-mile (16-kilometer) stretch of one of the busiest U.S. freeways for a massive 53-hour construction project.
