Left Coast Lifter
''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 (which appears on the left side of a typical map and also refers to the region's liberal, or "left leaning", political tradition). Operational history ''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 Hu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Eastern Span Replacement Of The San Francisco–Oakland Bay Bridge
The eastern span replacement of the San Francisco–Oakland Bay Bridge was a construction project to replace a seismically unsound portion of the Bay Bridge with a new self-anchored suspension bridge (SAS) and a pair of viaducts. The bridge is in the U.S. state of California and crosses the San Francisco Bay between Yerba Buena Island and Oakland. The span replacement took place between 2002 and 2013, and is the most expensive public works project in California history, with a final price tag of $6.5 billion, a 2,500% cost overrun from the original estimate of $250 million. Originally scheduled to open in 2007, several problems delayed the opening until September 2, 2013. With a width of , comprising 10 general-purpose lanes, it is the world's widest bridge according to Guinness World Records. The Bay Bridge has two major sections: the western suspension spans and their approach structures between San Francisco and Yerba Buena Island (YBI) and the structures between ...

Structural Engineers Association Of Northern California
The Structural Engineers Association of Northern California (SEAONC) is a structural engineering association established in 1930. Its headquarters are in San Francisco, California. Initially a club for structural engineers to exchange technical information, it evolved into a professional organization advising on the development of building code requirements and California legislation related to earthquake hazard reduction such as the Field Act and Alquist Priolo Special Studies Zone Act. SEAONC is the northern California section of the statewide Structural Engineers Association of California (SEAOC). SEAOC's ''Recommended Lateral Force Requirements,'' a.k.a. "Blue Book", first published in 1959, has since influenced the development of seismic analysis and design provisions in building codes nationwide.

Hurricane Sandy
Hurricane Sandy (unofficially referred to as ''Superstorm Sandy'') was an extremely destructive and strong Atlantic hurricane, as well as the largest Atlantic hurricane on record as measured by diameter, with tropical-storm-force winds spanning . The storm inflicted nearly $70 billion (2012 USD) in damage and killed 233 people across eight countries from the Caribbean to Canada. The eighteenth Tropical cyclone naming, named storm, tenth Atlantic hurricane, hurricane, and second major hurricane of the 2012 Atlantic hurricane season, Sandy was a List of Category 3 Atlantic hurricanes, Category 3 storm at its peak intensity when it made landfall in Cuba, though most of the damage it caused was after it became a Category 1-equivalent extratropical cyclone off the coast of the Northeastern United States. Sandy developed from a tropical wave in the western Caribbean Sea on October 22, quickly strengthened, and was upgraded to Tropical Storm Sandy six hours later. Sandy moved s ...

Spuyten Duyvil Bridge
The Spuyten Duyvil Bridge is a railroad swing bridge that spans the Spuyten Duyvil Creek between Manhattan and the Bronx, in New York City. The bridge is located at the northern tip of Manhattan where the Spuyten Duyvil Creek meets the Hudson River, approximately to the west of the Henry Hudson Bridge. The Spuyten Duyvil Bridge was built to carry two tracks but now carries only a single track on the eastern side of the span. It is part of the West Side Line, and is used by Amtrak trains traveling along the Empire Connection. The span is used by approximately 30 trains a day and is opened over 1,000 times per year, primarily during the summer months for Circle Line Sightseeing Cruises and recreational vessels. History A wooden railroad drawbridge across the Spuyten Duyvil was first constructed by the New York & Hudson River Railroad in 1849. The railroad continued southward along the West Side Line to St. John's Park Terminal in Lower Manhattan and carried both freight and ...

Tappan Zee Bridge (1955–2017)
The Governor Malcolm Wilson Tappan Zee Bridge, commonly known as the Tappan Zee Bridge, was a cantilever bridge in the U.S. state of New York. It was built from 1952 to 1955 to cross the Hudson River at one of its widest points, north of Midtown Manhattan, from South Nyack to Tarrytown. As an integral conduit within the New York Metropolitan Area, the bridge connected South Nyack in Rockland County with Tarrytown in Westchester County in the Lower Hudson Valley. Opened on December 14, 1955, the Tappan Zee Bridge was one of the primary crossings of the Hudson River north of New York City; it carried much of the traffic between southern New England and points west of the Hudson. The bridge was the longest bridge in New York State, a title retained by its replacement. The total length of the bridge approached . The cantilever span was , which provided a maximum clearance of over the water. The bridge was officially named after former governor Malcolm Wilson in 1994, though t ...

Hudson River
The Hudson River is a river that flows from north to south primarily through eastern New York. It originates in the Adirondack Mountains of Upstate New York and flows southward through the Hudson Valley to the New York Harbor between New York City and Jersey City, eventually draining into the Atlantic Ocean at Lower New York Bay. The river serves as a political boundary between the states of New Jersey and New York at its southern end. Farther north, it marks local boundaries between several New York counties. The lower half of the river is a tidal estuary, deeper than the body of water into which it flows, occupying the Hudson Fjord, an inlet which formed during the most recent period of North American glaciation, estimated at 26,000 to 13,300 years ago. Even as far north as the city of Troy, the flow of the river changes direction with the tides. The Hudson River runs through the Munsee, Lenape, Mohican, Mohawk, and Haudenosaunee homelands.
