Harbor Bridge Project
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 route will connect with SH 286 (the Crosstown Expressway) at its southern terminus and US 181 on the north. Groundbreaking on construction took place on August 8, 2016 and was scheduled to be completed by the spring of 2020, but was extensively delayed due to engineering and design issues, and is tentatively planned to be completed in 2025. History Planning for the bridge began in 2003 to address the maintenance and safety issues of the existing Corpus Christi Harbor Bridge as well as provide long term access to the Port of Corpus Christi to larger ship vessels (including Panamax). Texas Department of Transportation (TxDOT) awarded developer Flatiron/Dragados with the design–build contract ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Corpus Christi Ship Channel
The Corpus Christi Ship Channel is a deep water navigable ship canal located in Corpus Christi, Texas. It is part of the Port of Corpus Christi, managed and controlled by the Corpus Christi Port Authority. The depth of the channel is . It is used mostly for heavy industry Heavy industry is an industry that involves one or more characteristics such as large and heavy products; large and heavy equipment and facilities (such as heavy equipment, large machine tools, huge buildings and large-scale infrastructure); o ... and the export and import of goods. The channel dates back to the 1840s as a mud slough where cowboys hid and watched Comanche braves throw buffalo robes in the thick mud to prevent their horses from sinking. Years later a wooden bridge was constructed over the slough, at the time called Hall's Bayou.http://archive.caller.com/columnists/murphy-givens/the-bridge-over-halls-bayou-ep-361121356-316586761.html References {{Reflist Waterways in the United States Irr ...

Segmental Bridge
A segmental bridge is a bridge built in short sections (called segments), i.e., one piece at a time, as opposed to traditional methods that build a bridge in very large sections. The bridge is made of concrete that is either cast-in-place (constructed fully in its final location) or precast concrete (built at another location and then transported to their final location for placement in the full structure). These bridges are very economical for long spans (more than ), especially when access to the construction site is restricted. They are also chosen for their aesthetic appeal. History The first cantilevered segmental cast-in-place concrete bridge, built in 1930, was across Rio do Peixe in the state of Santa Catarina of Brazil. It was followed in 1951 by the prestressed concrete bridge across the Lahn River in , the first of many cantilevered bridges designed by . The first prestressed concrete bridge, assembled by several precast elements, was the across the river Marne in F ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Sam Houston Ship Channel Bridge
Sam Houston Tollway Ship Channel Bridge (formerly known as the Jesse H. Jones Memorial Bridge) is a span in Harris County, Texas. It was acquired from the then– Texas Turnpike Authority (TTA) (now North Texas Tollway Authority) on May 5, 1994, and is now a part of the Harris County Toll Road Authority system. The bridge opened to traffic in May 1982 and carries four lanes of the Sam Houston Tollway over the Houston Ship Channel with a clearance of . Conception The 1952 City of Houston planning document recommended a second loop designated the Outer Belt. Harris County took control of the project in 1960. Efforts to construct the Beltway 8 crossing started in the mid-1960s, culminating in an effort vetoed by Governor John Connally on June 18, 1967. Voters twice rejected bond funds for the bridge, so the effort was reconstituted as a toll bridge. This did not work at that time. In 1978, the Texas Turnpike Authority performed a study showing the project as feasible, and sold $1 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

National Transportation Safety Board
The National Transportation Safety Board (NTSB) is an independent U.S. government investigative agency responsible for civil transportation accident investigation. In this role, the NTSB investigates and reports on aviation accidents and incidents, certain types of highway crashes, ship and marine accidents, pipeline incidents, bridge failures, and railroad accidents. The NTSB is also in charge of investigating cases of hazardous materials releases that occur during transportation. The agency is based in Washington, D.C. It has four regional offices, located in Anchorage, Alaska; Denver, Colorado; Ashburn, Virginia; and Seattle, Washington. The agency also operates a national training center at its Ashburn facility. History The origin of the NTSB was in the Air Commerce Act of 1926, which assigned the United States Department of Commerce responsibility for investigating domestic aviation accidents. Before the NTSB, the Federal Aviation Administration's (FAA; at the t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Florida International University Pedestrian Bridge Collapse
The Florida International University pedestrian bridge collapse occurred on March 15, 2018, when a 175-foot-long (53 m) section of the FIU-Sweetwater UniversityCity Pedestrian Bridge collapsed while under construction. The collapse resulted in six deaths (one worker and five motorists), ten injuries (six serious and four minor), and eight vehicles being crushed underneath. Of the serious injuries, one employee was permanently disabled. At the time of the collapse, six lanes of road beneath the bridge were open to traffic. The pedestrian bridge was designed to connect the town of Sweetwater to the campus of Florida International University (FIU) in University Park, a suburb west of Miami, Florida, United States. The two were separated by a busy eight-lane highway, which the bridge was designed to span. The engineering design error that directly led to the collapse was identified by the National Transportation Safety Board (NTSB) as a miscalculation of r ...

Gordie Howe International Bridge
The Gordie Howe International Bridge (french: Pont International Gordie-Howe), known during development as the Detroit River International Crossing and the New International Trade Crossing, is a cable-stayed international bridge across the Detroit River, currently under construction. The crossing will connect Detroit and Windsor by linking Interstate 75, Interstate 94 and Interstate 96 in Michigan with Highway 401 in Ontario (through the Rt. Hon. Herb Gray Parkway extension of Highway 401). The bridge will provide uninterrupted freeway traffic flow, as opposed to the current configuration with the nearby Ambassador Bridge that connects to city streets on the Ontario side. The bridge is named after Canadian ice hockey player Gordie Howe, whose celebrated career included 25 years with the Detroit Red Wings, and who died two years before construction began. First proposed in 2004, the project was met with prominent opposition by Ambassador Bridge owner Manuel Moro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Post-tensioned Concrete
Prestressed concrete is a form of concrete used in construction. It is substantially "prestressed" ( compressed) during production, in a manner that strengthens it against tensile forces which will exist when in service. Post-tensioned concreted is "structural concrete in which internal stresses have been introduced to reduce potential tensile stresses in the concrete resulting from loads." This compression is produced by the tensioning of high-strength "tendons" located within or adjacent to the concrete and is done to improve the performance of the concrete in service. Tendons may consist of single wires, multi-wire strands or threaded bars that are most commonly made from high-tensile steels, carbon fiber or aramid fiber. The essence of prestressed concrete is that once the initial compression has been applied, the resulting material has the characteristics of high-strength concrete when subject to any subsequent compression forces and of ductile high-strength steel when subje ...

Launching Gantry
A launching gantry (also called beam launcher, girder launcher, bridge building crane, and bridge-building machine, locally nicknamed the "Iron Monster") is a special-purpose mobile gantry crane used in bridge construction, specifically segmental bridges that use precast box girder bridge segments or precast girders in highway and high-speed rail bridge construction projects. The launching gantry is used to lift and support bridge segments or girders as they are placed while being supported by the bridge piers instead of the ground. While superficially similar, launching gantry machines should not be confused with movable scaffolding systems, which also are used in segmental bridge construction. Both feature long girders spanning multiple bridge spans which move with the work, but launching gantry machines are used to lift and support precast bridge segments and bridge girders, while movable scaffolding systems are used for cast-in-place construction of bridge segments.
