One of the busiest freeways in California, the 405, stands vacant as workers demolish the south side of Mulholland overpass on the freeway during the 53-hour total freeway closure. The massive traffic disruptions expected throughout the region did not materialize. The bridge is being demolished as 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. UPI/Jim Ruymen
