    State officials say one of the steel rods that anchors the Bay Bridge eastern span's tower to its foundation is fractured.

    The San Francisco Chronicle reports Wednesday that project chief engineer Brian Maroney says officials do not yet know whether stewing in the saltwater caused the rod to corrode. He said tests would be needed to determine why the rod fractured somewhere above its base, the newspaper reported. Maroney says he is hopeful that no other rods have been damaged.

    The rod was one of 424 installed at the base of the tower to strengthen the $6.4 billion bridge against a massive earthquake. The new span opened in September 2013.
