OAKLAND (CBS SF) — A massive crane, soaring more than 100 feet in the air, slipped under the Golden Gate and San Francisco-Oakland Bay Bridge early Thursday on its way to the Port of Oakland.

The freighter Zhen Hua 26 hovered off the Northern California coast until weather and tide conditions were just right to allow the crane to pass over the bridges with 10 or less feet of clearance.
