Carmageddon Redux on the 405 Freeway ends in time for the Monday commute, with workers having finished extra maintenance during the two-day closure.Carmageddon Redux came to an end according to plan before Monday's commute got underway. But unlike last year's freeway closure, which wrapped up an unexpected 17 hours ahead of schedule, this time construction crews used most of their allotted time to make as many improvements to the 405 Freeway as possible, officials said.
