Caltrans Orders More Testing After Defective Bolts Found on New Bay Bridge

SAN FRANCISCO BAY (KRON) — Caltrans is ordering a series of measures to make sure the new Bay Bridge will be safe when it opens later this year following the discovery of a series of defective bolts on the new span.

It’s now been three weeks since inspections showed dozens of bolts designed to secure the new span snapped not long after they were installed. Those bolts were part of an extensive system designed to make sure the new bridge remains safe during a major earthquake.

Now KRON 4 has obstained a memo from the head of Caltrans to bridge project managers requiring a series of steps to make sure the rest of the span isn’t defective.

Those include more testing on the bolts to find out what caused them to break in the first place, tests on other parts of the bridge using parts from the same company that supplied the bolts, Dyson Corporation, a family-run company based in Ohio. Caltrans also wants certification from the contractor that their work is in compliance with the original contract.

Caltrans says it still believes the new bridge will open on schedule on the Tuesday following the Labor Day weekend this year. However the memo makes clear that the safety of the bridge is more important than meeting an arbitrary timetable.

Stay tuned to KRON 4 and for the latest on this developing story.
