Starting at midnight Friday, July 15th, 10 miles of the San Diego Interstate 405 Freeway will be closed. Rightfully named Carmageddon, the phenomenon will cloud Southern California with the closure of a portion of the most clogged freeway system in the city, all the way from the Hollywood Hills to the 10 Santa Monica Freeway.

Knowing the doomsday-like phenomenon will not be a simple event, even local officials gave in to calling it Carmageddon.

Caltran workers will work on demolishing a bridge during Carmageddon, and the freeway portion is expected to reopen on Monday, July 18.

More than 200,000 cars use that highway each weekend, which could lead to massive delays. However, a full shutdown is necessary to replace the 50-year-old Mulholland Bridge as a part of construction efforts of the planned $1 billion project to widen the highway and add additional carpool lanes. It is expected to be done in 2013.

Free rides on the subway and certain bus lines are offered by transit officials. While metro buses and trains will not run later than usual, enhanced service on many lines is provided throughout the weekend.
