The long weekend's 80-hour "Jamzilla" closure along the 405 Freeway through the Sepulveda Pass came to an end at about 5 a.m. Tuesday, about an hour ahead of schedule and just in time for the morning commute.
California Highway Patrol Officer Francisco Villalobos said that all lanes in both directions on the freeway between Sunset and Ventura boulevards were fully open, and that traffic was beginning to move through just ahead of rush hour.
Transportation officials said the 5.6-mile closure was necessary for a project that would ultimately add a northbound carpool lane between the 10 and 101 freeways, along with other improvements along that stretch.
Traffic because of the construction appeared heavier Monday than over the rest of the weekend.
"As you probably know, if you tried to drive the northbound 405 over the Sepulveda Pass -- there were significant delays with heavy traffic trying to squeeze into two lanes," the Los Angeles County Metropolitan Transportation Authority posted on its blog.
Earlier in the weekend, MTA spokesman Paul Gonzales said there were only short delays that showed "a lot of people have taken to heart our warnings about staying out of the area."
