Warnings of a colossal traffic jam were in place over the weekend when a 10-mile stretch of a busy Los Angeles road was closed for construction.
But fears of the so-called Carmageddon eased when the work cruised calmly to a smooth finish.
Interstate 405 reopened nearly a day ahead of schedule with no significant problems.
Los Angeles mayor Antonio Villaraigosa hailed the contractors for finishing the work ahead of schedule and thanked the residents for staying off the roads.
"We couldn't have done this without the co-operation of this city," he said.
He also praised news outlets for spreading awareness about the event well in advance.
Residents and motorists were warned of huge traffic jams which could bring much of Los Angeles to a standstill, if they drove as usual over the weekend. But the weekend witnessed only light traffic.
