LOS ANGELES, CA - JULY 16: A pedestrian passes a detour sign as drivers heed the advice of widely-publicized warnings to stay off the roadways while workers demolish the south side of Mulholland overpass on the 405 freeway during the 53-hour total freeway closure dubbed "Carmageddon" for the resulting massive traffic disruptions expected throughout the region, on July 16, 2011 in Los Angeles, California. The bridge is being demolished part of a $1 billion project to add carpool lanes and make other improvements along the 405 freeway from Orange County to the city of San Fernando.
