Tanker hits San Francisco Bay Bridge: Coast Guard SAN FRANCISCO (Reuters) - An oil tanker struck a tower of the San Francisco Bay Bridge on Monday but did not appear to spill any oil into the bay, the U.S. Coast Guard said. The 750-foot-long "Overseas Reymar," sailing under a Marshall Islands flag, was empty except for water that was used as ballast, U.S. Coast Guard Lieutenant Heather Lampert said. None of the channels or ports in the San Francisco Bay were listed as shut as of Monday afternoon, according to the Coast Guard's website. Inspectors have been sent to check for damage to the bridge that spans San Francisco and Oakland, said California Department of Transportation spokeswoman Traci Ruth. In 2007, the tanker Cosco Busan spilled more than 200,000 liters of heavy fuel oil after striking the Bay Bridge in heavy fog.
