Report: Supplier knew of problems before Bay Bridge rods cracked

OAKLAND, Calif. (KGO) -- A new report claims that the supplier of the steel rods that cracked on the Bay Bridge in 2013 never told Caltrans the same thing happened with nearly identical rods made for a Washington state bridge in 2009.

The San Francisco Chronicle reports on a review released by California bridge officials. It states Ohio's Dyson Corporation knew of rod problems six months after shipping 96 of them to California in 2008.

Thirty-two of those rods sat in rainwater for five years, exposing them to corrosive hydrogen. They snapped after being cinched down in 2013.

The construction failure cost toll payers $45 million.

Dyson Corporation has not responded to requests for comment.
