Caltrans Says Errors Led to 24 Accidents

In the past 3 1/2 years, Caltrans employees issued route permits that sent at least 24 oversized trucks under bridges too low for them, including three mobile homes that slammed into bridges, several cranes that damaged overpasses and a truck carrying a solar turbine that struck an overpass because the load was more than a foot too high.

Details of the accidents were released Wednesday by Caltrans officials, who had originally portrayed as an isolated incident a similar mistake that resulted in the July death of a Westminster man.

In that accident, 36-year-old Tam Trong Tran was crushed to death when a 7,000-pound fuel tank was knocked off a 15-foot big rig passing under the 14-foot, 10-inch La Palma Avenue overpass in Anaheim. At the time, officials said it was one of three incorrect truck routes approved since June, which they said were the first errors made in the last three years.

But the list released Wednesday is much longer. Although no known injuries resulted from the other mistakes, many were substantial errors that sent loads as much as 17 inches too high barreling toward freeway overpasses for which they were too big. Accidents this year did at least $45,000 in damage to property, vehicles and cargo.

Caltrans requires all trucks higher than 14 feet to get a permit to travel on state freeways and other roads. A permit is considered to be issued in error if the load clears the bridge with less than a 3-inch margin. Caltrans officials say it is impossible to determine how many times that occurs.

The information about the additional accidents comes several weeks after a union grievance was filed against Caltrans by an agency employee that cited chronic understaffing and unreasonable production standards in the San Bernardino office, where many permits are issued.

Tran's death has focused scrutiny on the permit writing office there, where some employees say the management has ignored problems for years.

"This was truly an accident waiting to happen," said Joe Weber, the permit writer in the San Bernardino office who filed the union grievance 12 days after Tran's death. "If they don't change things, it will happen again."

Weber described a frenetic office where few people last for more than a year or two and employees are often required to work overtime to keep up with the booming truck business.
