Investigators say the Coast Guard's vessel-traffic authorities did not warn a cargo ship it was about to plow into the Bay Bridge in the minutes before the collision.
The National Transportation Safety Board says the Coast Guard's
Vessel Traffic Service asked the Cosco Busan what its intentions
were as it made its way through a fog bank.
The ship's unusual course had drawn the attention of the Coast Guard because it was traveling parallel to the bridge.
But the Coast Guard VTS did not warn the ship it was headed for the bridge footing.
The NTSB said the VTS plays only an advisory role to the shipping traffic in the bay and cannot order vessels to change course.
