context_page_description: Left Coast Lifter is a floating derrick barge or sheerleg which was built to assist in the eastern span replacement of the San Francisco–Oakland Bay Bridge. The barge carries a shear legs crane which is the largest barge crane ever used on the U.S. West Coast. The barge's name is taken from "Left Coast", a slang term for the West Coast of the United States.
context_section_description: Left Coast Lifter was built for the American Bridge/Fluor joint venture (ABFJV), which was the lead contractor on the self-anchored suspension eastern span replacement. The barge was built in Portland, Oregon by U.S. Barge, LLC and ferried to Shanghai, where it was fitted with a shear-leg crane manufactured by Shanghai Zhenhua Port Machinery Co. Ltd (ZPMC). The completed sheerleg was ferried back to the United States on a semi-submersible heavy-lift ship, Zhen Hua 22 (IMO 8106446). The total cost was approximately US$50,000,000 (equivalent to $59,590,000 in 2019).
  Before Left Coast Lifter was fitted out with the crane for bridge construction, it was deemed to violate the Jones Act, specifically in that since the integral crane would be built and installed in China, it could not be used to transport goods by water between U.S. ports. Therefore its first job, prior to installation of the crane, was to haul dredged materials to Long Beach.
