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 Harbor Bridge Project (or New Harbor Bridge or US 181 Harbor Bridge) is the replacement of the existing through arch bridge that crosses the Corpus Christi Ship Channel, which serves the Port of Corpus Christi in Corpus Christi, Texas, with a modern cable-stayed bridge design.
The project required about 127,000 cubic metres (166,000 cu yd) of concrete, 19,000 tonnes (21,000 short tons) of steel for the reinforced concrete, and 5,000 tonnes (5,500 short tons) of pre-stressed steel for the cables and shrouds. The builder claims that the lifetime of the bridge will be at least 120 years.
A cantilever bridge is a bridge built using structures that project horizontally into space, supported on only one end (called cantilevers).For small footbridges, the cantilevers may be simple beams; however, large cantilever bridges designed to handle road or rail traffic use trusses built from structural steel, or box girders built from prestressed concrete.
This list of the longest arch bridge spans ranks the world's arch bridges by the length of their main span. The length of the main span is the most common way to rank bridges as it usually correlates with the engineering complexity involved in designing and constructing the bridge. [ 1 ]
A self-anchored suspension bridge is a suspension bridge type in which the main cables attach to the ends of the deck, rather than directly to the ground or via large anchorages. [1] The design is well-suited for construction atop elevated piers, or in areas of unstable soils where anchorages would be difficult to construct.
Left Coast Lifter made its first lift on the new Tappan Zee bridge in April 2015, [22] a steel-reinforced concrete pile cap which formed part of the bridge's foundation. The massive crane was being used for heavy lifts of large bridge sections, [ 23 ] and placed the final steel girder for the new Rockland-bound (westbound) span in October 2016 ...
The LSIBA issued the updated financial plan for the Ohio River Bridges project on December 16, 2010. The plan envisioned roughly half of the project's costs being financed through $1.00 tolls on the proposed I-65 (northbound) and I-265 and the existing I-65 (southbound) and I-64 Ohio River crossings in the Louisville area. While the financial ...
