Mezcala Bridge
The Mezcala Bridge (also known as the Mezcala-Solidaridad Bridge), is a cable-stayed bridge located in the state of Guerrero on Highway 95D in Mexico. It spans the Balsas River (known locally as the Mezcala River) close to the western Pacific coast of the country. This bridge, with a total length of and six uneven spans completed in 1993, has been in service since 1994 as a toll bridge. It was the world's ''tallest'' bridge from its opening in 1993 to 1998 when the Akashi-Kaikyo Bridge in Japan was opened. It was also the ''highest'' bridge in Mexico and the second highest multiple cable-stayed bridge to be built in the world. The Mezcala Bridge was built as part of the 1989–1994 highway restructuring program in Mexico, which reduced the distance of Highway 95 between Cuernavaca and Acapulco by 49 km. The bridge suffered a fire in one of its cable systems in March 2007 when there was an accident on the main deck. The fire resulted when a coconut-carrying truck collided ...

List Of Tallest Bridges In The World
This list of tallest bridges includes bridges with a structural height of at least . The of a bridge is the maximum vertical distance from the uppermost part of a bridge, such as the top of a bridge tower, to the lowermost exposed part of the bridge, where its piers, towers, or mast pylons emerge from the surface of the ground or water. Structural height is different from , which measures the maximum vertical distance between the bridge deck (the road bed of a bridge) and the ground or water surface beneath the bridge span. A separate list of highest bridges ranks bridges by deck height. Structural height and deck height The difference between tall and high bridges can be explained in part because some of the highest bridges are built across deep valleys or gorges. For example, (as of 1 July 2020) the Duge Bridge is the highest bridge in the world, but only the fifteenth tallest. This bridge spans a deep river gorge. The bridge's two towers, built on either rim of the gorge, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mexican Federal Highway 95D
Federal Highway 95D is a toll highway connecting Mexico City to Acapulco, Guerrero. Highway 95D is among the most important toll roads in the country, serving as a backbone for traffic out of Mexico City toward Morelos and tourist destinations in Guerrero. Three segments, from north to south, comprise Federal Highway 95: the segment between Mexico City and Cuernavaca, the segment from Cuernavaca to Acapulco (commonly known as the Autopista del Sol or Sun Highway), and the Maxitúnel Interurbano Acapulco, separated from the other two segments and offering a bypass under local traffic in Acapulco. México–Cuernavaca The first and oldest segment of Highway 95D is that running between Mexico City and Cuernavaca, which was the second toll road in the country. The original construction of the highway was performed by Compañía Constructora del Sur, S.A. de C.V., a state-controlled predecessor to Caminos y Puentes Federales, the government agency that maintains the México–Cuernava ...

Celebration Of Mexican Political Anniversaries In 2010
In 2010, Mexico celebrated both the 200th anniversary of its Independence and 100th anniversary of its Revolution. The entire year was proclaimed by President Felipe Calderón as "Año de la Patria", or "Year of the Nation". 16 September 1810 is the day of the "Grito de Dolores" or Miguel Hidalgo's call to take up arms against the Spanish colonial government. The start of the Mexican Revolution is celebrated as being 20 November 1910, when Francisco "Pancho" Villa and Pascual Orozco led the first insurrectionist attack against the regime of Porfirio Díaz. Events and other promotions of these celebrations were designed to link of Mexico's identity and historic continuity. During a speech at the inauguration of the Casa de Allende (Allende House) Historic Museum, President Felipe Calderón called upon Mexico to use the upcoming anniversaries to reflect on where the country has been and to think about what kind of Mexico descendants will inherit in the future. He said the vision of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Buildings And Structures In Guerrero
A building or edifice is an enclosed Structure#Load-bearing, structure with a roof, walls and window, windows, usually standing permanently in one place, such as a house or factory. Buildings come in a variety of sizes, shapes, and functions, and have been adapted throughout history for numerous factors, from building materials available, to weather conditions, land prices, ground conditions, specific uses, monument, prestige, and aesthetic reasons. To better understand the concept, see ''Nonbuilding structure'' for contrast. Buildings serve several societal needs – occupancy, primarily as shelter from weather, security, living space, privacy, to store belongings, and to comfortably live and work. A building as a shelter represents a physical separation of the :Human habitats, human habitat (a place of comfort and safety) from the ''outside'' (a place that may be harsh and harmful at times). buildings have been objects or canvasses of much architecture, artistic expression. ...

Bridges Completed In 1993
A bridge is a structure built to span a physical obstacle (such as a body of water, valley, road, or railway) without blocking the path underneath. It is constructed for the purpose of providing passage over the obstacle, which is usually something that is otherwise difficult or impossible to cross. There are many different designs of bridges, each serving a particular purpose and applicable to different situations. Designs of bridges vary depending on factors such as the function of the bridge, the nature of the terrain where the bridge is constructed and anchored, the material used to make it, and the funds available to build it. The earliest bridges were likely made with fallen trees and stepping stones. The Neolithic people built boardwalk bridges across marshland. The Arkadiko Bridge, dating from the 13th century BC, in the Peloponnese is one of the oldest arch bridges in existence and use. Etymology The ''Oxford English Dictionary'' traces the origin of the word ''bridge' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cable-stayed Bridges In Mexico
A cable-stayed bridge has one or more ''towers'' (or ''pylons''), from which cables support the bridge deck. A distinctive feature are the cables or stays, which run directly from the tower to the deck, normally forming a fan-like pattern or a series of parallel lines. This is in contrast to the modern suspension bridge, where the cables supporting the deck are suspended vertically from the main cable, anchored at both ends of the bridge and running between the towers. The cable-stayed bridge is optimal for spans longer than cantilever bridges and shorter than suspension bridges. This is the range within which cantilever bridges would rapidly grow heavier, and suspension bridge cabling would be more costly. Cable-stayed bridges found wide use in the late 19th century. Early examples, including the Brooklyn Bridge, often combined features from both the cable-stayed and suspension designs. Cable-stayed designs fell from favor in the early 20th century as larger gaps were bridg ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hydrocarbon
In organic chemistry, a hydrocarbon is an organic compound consisting entirely of hydrogen and carbon. Hydrocarbons are examples of group 14 hydrides. Hydrocarbons are generally colourless and Hydrophobe, hydrophobic; their odor is usually faint, and may be similar to that of gasoline or Naphtha, lighter fluid. They occur in a diverse range of molecular structures and phases: they can be gases (such as methane and propane), liquids (such as hexane and benzene), low melting solids (such as paraffin wax and naphthalene) or polymers (such as polyethylene and polystyrene). In the fossil fuel industries, ''hydrocarbon'' refers to naturally occurring petroleum, natural gas and coal, or their hydrocarbon derivatives and purified forms. Combustion of hydrocarbons is the main source of the world's energy. Petroleum is the dominant raw-material source for organic commodity chemicals such as solvents and polymers. Most anthropogenic (human-generated) emissions of greenhouse gases are eithe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
High-density Polyethylene
High-density polyethylene (HDPE) or polyethylene high-density (PEHD) is a thermoplastic polymer produced from the monomer ethylene. It is sometimes called "alkathene" or " polythene" when used for HDPE pipes. With a high strength-to-density ratio, HDPE is used in the production of plastic bottles, corrosion-resistant piping, geomembranes and plastic lumber. HDPE is commonly recycled, and has the number "2" as its resin identification code. In 2008, the global HDPE market reached a volume of more than 30 million tons. Properties HDPE is known for its high strength-to-density ratio. The density of HDPE ranges from 930 to 970 kg/m3. Although the density of HDPE is only marginally higher than that of low-density polyethylene, HDPE has little branching, giving it stronger intermolecular forces and tensile strength (38 MPa versus 21 MPa) than LDPE. The difference in strength exceeds the difference in density, giving HDPE a higher specific strength. It is also harder and ...

Construction
Construction are processes involved in delivering buildings, infrastructure, industrial facilities, and associated activities through to the end of their life. It typically starts with planning, financing, and design that continues until the asset is built and ready for use. Construction also covers repairs and maintenance work, any works to expand, extend and improve the asset, and its eventual demolition, dismantling or wikt:decommission, decommissioning. The construction industry contributes significantly to many countries' gross domestic products (Gross domestic product, GDP). Global expenditure on construction activities was about $4 trillion in 2012. In 2022, expenditure on the construction industry exceeded $11 trillion a year, equivalent to about 13 percent of global Gross domestic product, GDP. This spending was forecasted to rise to around $14.8 trillion in 2030. The construction industry promotes economic development and brings many non-monetary benefits to many cou ...
