Caltrans found problems with tests

SACRAMENTO, Calif.

The Sacramento Bee reports that after engineers in December started reviewing records of the tests, they found doctored data and other suspicious tests.

The newspaper says engineers were trying to determine how much trouble a single rogue technician had caused, but found problems that extended beyond that former employee and also called into question testing of the new Bay Bridge and three other key Bay Area spans.

The assessment follows assertions by California Department of Transportation officials that their tests were valid and that the Bay Bridge is safe.
