THE STATE

I-5 getting back in the flow

Lanes are reopening three days after deadly tunnel crash, but it will be months before the route returns to normal.

Caltrans announced plans to reopen portions of Interstate 5 near Santa Clarita faster than expected following a deadly multi-vehicle crash and fire, but warned Sunday that it would be months before the state's principal north-south highway returned to normal.

Two northbound truck lanes reopened to general traffic Sunday afternoon, and authorities said they planned to reopen the main southbound roadway before this morning's rush hour. The main northbound lanes were expected to reopen later, possibly as early as this afternoon.

Still, Douglas Failing, regional director for the California Department of Transportation, said it probably would be months before the agency could reopen the southbound truck tunnel lanes where more than two dozen trucks crashed and burned late Friday. In the meantime, he said, the road will be more congested.

Officials warned commuters and truckers to expect delays of as much as two hours when workweek traffic resumes today, and urged them to take alternative routes or public transportation.

I-5 closure: An article in Monday's Section A about plans to reopen Interstate 5 near Santa Clarita said most of the goods arriving through the ports of Los Angeles and Long Beach are hauled by rail. Most port cargo is hauled by trucks.

Metrolink, the commuter rail line, said it would put additional cars onto its trains leaving Lancaster in the predawn hours today, and that extra trains would operate the rest of the day.

Even so, railroad officials offered this advice to riders: Bring a book, wear comfortable shoes and prepare to stand.

Three people died in the Friday night pileup, which occurred just south of the intersection of I-5 and California 14, the Antelope Valley Freeway.

It was not clear what caused the chain-reaction crash Friday, and the California Highway Patrol said its investigation into the accident would be lengthy. Heavy-equipment crews finished pulling the wreckage of 30 commercial vehicles and one passenger car out of the tunnel early Sunday, allowing inspectors to go to work to determine the extent of the damage. The scene they found was sobering.

The tunnel was charred and still smoldering, the roadway pocked, the ceiling blistered. The highway's asphalt shoulders resembled a solidified lava flow. Sections of concrete walls had peeled away, exposing steel reinforcement bars, some of which appeared to be askew.

"The structural integrity of the sidewalls has been compromised," Failing said.

He said inspectors had taken core samples of concrete and steel, and would examine them microscopically to determine the extent to which they might have been weakened.

"The samples will let us know the strength of the wall," he said.

As a cautionary move, Caltrans crews will also put beams in the middle of the tunnel to reinforce concrete girders running across the top.

Caltrans officials said that some of the trucks pulled out of the tunnel had been reduced to skeletal frames lumped amid unrecognizable, molten debris. Temperatures inside the tunnel during the fire were estimated to have ranged from 1,000 to 1,400 degrees.

Still, Failing said there appeared to be no significant damage to the deck of the main I-5 roadway where it passed over the tunnel, and the girders supporting the structure appeared to be sound.

"We're not seeing any cracking," he said. "I'm very pleased with how well this bridge held up."

To aid in the repair effort, Gov. Arnold Schwarzenegger declared a state of emergency for Los Angeles County, allowing the possibility of state aid to local authorities.

Two men and an infant died in the accident, and their bodies had not been identified Sunday night. Authorities said 10 people were hospitalized, none with critical injuries, and 10 others had run out of the tunnel uninjured. The remainder of those in the 31 vehicles were unaccounted for. Investigators said they did not believe that anyone else had died.

Some truckers familiar with the 550-foot-long tunnel where the accident occurred said it has long had a reputation for being dangerous. Javier Pablo, 37, of La Mirada, who hauls cargo out of the Port of Los Angeles, described it as dimly lit and particularly dangerous after a rainstorm, which was the situation Friday evening.

"You don't know what's going on inside that tunnel until you are inside, but everyone keeps going," he said. Other truckers made similar complaints in e-mails to The Times, and also said there was a blind curve inside the structure.

Caltrans' Failing said it was the first he had heard of any problems with the tunnel. He added that any dangers might be the result of risky driving rather than poor design. Still, he said he had ordered an analysis of accident rates to see if the tunnel has a pattern of problems.

The tunnel, built in the 1970s, is part of a four-mile-long, two-lane bypass around the intersection with the 14 Freeway. Trucks continuing on I-5 are required to use the bypass, but automobile drivers sometimes opt to use it as well.

Interstate 5 handles a significant portion of the truck traffic up and down the West Coast, from Mexico to Canada. The portion around Santa Clarita handles 225,000 vehicles a day, including many trucks going in and out of the ports of Los Angeles and Long Beach.
