One team of CHP specialists was working to identify the missing drivers as well as passengers and witnesses. Another team was working to identify the commercial vehicles – some of them burned to charred metal frames – through the trucking companies. Coroner’s investigators have been through all the vehicles and believe there are no more bodies, Stanley said. The cause of the crash has not been determined. Fire raged in the tunnel overnight and into Saturday, compromising the structure. Passenger lanes cross over the damaged tunnel and state Transportation Department officials initially thought it could take days to ensure they were structurally sound. The freeway was shut down over the weekend, and commuters were warned to find alternate routes to work Monday. But crews completed shoring up the tunnel, making it safe for repair teams to move in. Engineers determined the freeway was safe, and all lanes were opened shortly after 3 a.m. “It is, for us, a very good day here in California,” said Doug Failing, Caltrans district director for Los Angeles and Ventura counties. “I got into this business because I love seeing traffic move.” Failing said he will have a better idea of when the tunnel will open at the end of the week when he gets test results back. Concrete and steel reinforcement samples are being tested at a Texas lab to determine how the tunnel materials withstood the temperatures that reached 1,400degrees Fahrenheit. Caltrans’ goal, he said, is to repair the tunnel without closing the freeway. “I-5 is open to traffic, and it is our intention to keep it that way,” Failing said. During the repairs, lighting will also be improved in the tunnel. There is no cost estimate for the repairs, but Caltrans has an emergency authorization of $2.25 million for the initial work. For now, all lanes are open except for the southbound I-5 connector to northbound Route 14. And it could be weeks or months before the southbound truck tunnel reopens. “The southbound truck bypass is closed and will remain closed for an indefinite period of time,” Failing said. Caltrans and the city of Santa Clarita urged commuters to continue seeking alternates because the endless stream of trucks that traverse California’s main north-south freeway artery will share the road with passenger vehicles – a rough mix on the busy road to work. The speed limit has been reduced to 55 mph. To help reduce the impact of the freeway mess on commuters, Metrolink expanded its service between northern Los Angeles County and downtown Los Angeles. The additional service will continue today. On Monday, the I-5 and the Antelope Valley (14) Freeway that feeds it just south of the tunnel were exceptionally clear. Even though southbound freeway lanes were open, motorists said they opted for the train to avoid the ride home, unaware northbound lanes also would reopen ahead of schedule. “I didn’t want to drive home,” said Michelle Debardas of Valencia, a Metrolink first-time rider who works at a Glendale title company. “Getting to work didn’t look so bad, but coming home could take hours.” On Sunday, reporters brought up truckers’ concerns about the tunnel’s safety. “Quite frankly, I was caught by surprise at that,” Failing said. “We have had no record of complaints in my office.” His staff has looked at accident records from 2004 through 2006 at the tunnel site. “During that three-year period, we’ve only identified five accidents that happened in that stretch,” Failing said. He said the agency will follow up on the complaints. “A tunnel is not usually your first choice when you are trying to solve a transportation problem, but at some point in time a tunnel is the only choice you have available,” Failing added. email@example.com 160Want local news?Sign up for the Localist and stay informed Something went wrong.

But even as traffic concerns eased, officials began stepping up their probe into what set off the fiery collision of 30 trucks and a car on a rainy Friday night, leaving three dead and 10 injured. At least nine drivers who apparently escaped from vehicles trapped in the burning truck bypass tunnel in the Newhall Pass had not yet contacted the California Highway Patrol, officials said. Los Angeles trucker Ricardo Cibrian of Los Angeles is presumed to be one of the two men killed in the crash. Trucker Hugo Rodriguez and his 6-year-old son, Isaiah, are the other two believed to have died. They reportedly were from Fresno. “This is the worst accident that I have personally seen,” said Warren Stanley, assistant chief for CHP’s Southern Division and a 25-year CHP veteran. COMMUTE: Officials hope to keep tunnel open during repair. By Jerry Berrios and Patricia Farrell Aidem STAFF WRITERS Traffic whizzed easily through the normally clogged Newhall Pass on Monday after Interstate 5 lanes reopened ahead of schedule and investigators continued to search for clues to a deadly chain-reaction crash that closed the key north-south highway for days.
