‘Carmageddon II’ came to an end ahead of schedule, with all lanes of the 405 Freeway through the Sepulveda Pass re-opened to traffic by midnight Sunday. Crews were required to finish their work by a deadline of 5 a.m. on Monday morning, but they wrapped up with time to spare. The two-day closure of the 10-mile stretch of the 405 was part of a $1-billion, four-year project to expand the notoriously congested freeway with a northbound carpool lane.
