Coatzacoalcos Underwater Tunnel
The Coatzacoalcos Underwater Tunnel is a tunnel under the Coatzacoalcos River, connecting the cities of Coatzacoalcos and Villa de Allende in the Mexican state of Veracruz. The tunnel was formally opened on April 27, 2017, making it the first undersea tunnel in Mexico. after a 13-year construction process characterized by delays and increased costs and for which it has been described as a "monument to corruption". It is operated by a subsidiary of IDEAL, a company controlled by Carlos Slim. History Existing river crossings With the development of petrochemical complexes on the east bank of the river, the two existing crossings were insufficient for traffic. The first crossing to open was the Coatzacoalcos I bridge, which carries two-lane Mexican Federal Highway 180 and a rail line across the river and opened on March 18, 1962. In 1984, the four-lane Coatzacoalcos II bridge, formally named the , opened to traffic on the mainline of Mexican Federal Highway 180D; this bridge, buil ...

Coatzacoalcos
Coatzacoalcos () is a major port city in the southern part of the Mexican state of Veracruz, mostly on the western side of the Coatzacoalcos River estuary, on the Bay of Campeche, on the southern Gulf of Mexico coast. The city serves as the municipal seat of the municipality of the same name. It is the state's third largest city, after Veracruz City and Xalapa. Etymology Coatzacoalcos comes from a Nahuatl word meaning "site of the Snake" or "where the snake hides." According to the legend, this is where the god Quetzalcoatl made his final journey to the sea in around 999 and he made his promise to return. History Coatzacoalcos sits within the Olmec heartland. Excavations in 2008 for a tunnel under the Coatzacoalcos River indicate a substantial pre-Hispanic population. By the time of the Spanish arrival the area was under Mayan influence. In 1522, Hernán Cortés ordered Gonzalo de Sandoval to fund a settlement near Guazacualco. Sandoval named it Villa del Espíritu Santo. ...

Tunnels Completed In 2017
A tunnel is an underground passageway, dug through surrounding soil, earth or rock, and enclosed except for the entrance and exit, commonly at each end. A pipeline is not a tunnel, though some recent tunnels have used immersed tube construction techniques rather than traditional tunnel boring methods. A tunnel may be for foot or vehicular road traffic, for rail traffic, or for a canal. The central portions of a rapid transit network are usually in the tunnel. Some tunnels are used as sewers or aqueducts to supply water for consumption or for hydroelectric stations. Utility tunnels are used for routing steam, chilled water, electrical power or telecommunication cables, as well as connecting buildings for convenient passage of people and equipment. Secret tunnels are built for military purposes, or by civilians for smuggling of weapons, contraband, or people. Special tunnels, such as wildlife crossings, are built to allow wildlife to cross human-made barriers safely. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Undersea Tunnels In North America
The underwater environment is the region below the surface of, and immersed in, liquid water in a natural or artificial feature (called a body of water), such as an ocean, sea, lake, pond, reservoir, river, canal, or aquifer. Some characteristics of the underwater environment are universal, but many depend on the local situation. Liquid water has been present on Earth for most of the history of the planet. The underwater environment is thought to be the place of the origin of life on Earth, and it remains the ecological region most critical to the support of life and the natural habitat of the majority of living organisms. Several branches of science are dedicated to the study of this environment or specific parts or aspects of it. A number of human activities are conducted in the more accessible parts of the underwater environment. These include research, underwater diving for work or recreation, and underwater warfare with submarines. It is hostile to humans in many ways an ...

Immersed Tube
An immersed tube (or immersed tunnel) is a kind of undersea tunnel composed of segments, constructed elsewhere and floated to the tunnel site to be sunk into place and then linked together. They are commonly used for road and rail crossings of rivers, estuaries and sea channels/harbours. Immersed tubes are often used in conjunction with other forms of tunnel at their end, such as a cut and cover or bored tunnel, which is usually necessary to continue the tunnel from near the water's edge to the entrance (portal) at the land surface. Construction The tunnel is made up of separate elements, each prefabricated in a manageable length, then having the ends sealed with bulkheads so they can be floated. At the same time, the corresponding parts of the path of the tunnel are prepared, with a trench on the bottom of the channel being dredged and graded to fine tolerances to support the elements. The next stage is to place the elements into place, each towed to the final location, in mo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
2017 Chiapas Earthquake
The 2017 Chiapas earthquake struck at 23:49 CDT on 7 September (local time; 04:49 on the 8th UTC) in the Gulf of Tehuantepec off the southern coast of Mexico near the state of Chiapas, approximately southwest of Pijijiapan (alternately, south-southwest of Tres Picos), with a Mercalli intensity of IX (''Violent''). The moment magnitude was estimated to be . The earthquake caused all of Mexico City to tremble, prompting people to evacuate after the early warning system was triggered. It also generated a tsunami with waves above tide level; and tsunami alerts were issued for surrounding areas. Mexico's president called it the strongest earthquake recorded in the country in a century. It was also the second strongest recorded in the country's history, behind the magnitude 8.6 earthquake in 1787, and the largest recorded globally in 2017. Tectonic setting The Gulf of Tehuantepec lies above the convergent boundary where the Cocos Plate is being subducted below the North Ameri ...

Olmec
The Olmecs () were the earliest known major Mesoamerican civilization. Following a progressive development in Soconusco, they occupied the tropical lowlands of the modern-day Mexican states of Veracruz and Tabasco. It has been speculated that the Olmecs derived in part from the neighboring Mokaya or Mixe–Zoque cultures. The Olmecs flourished during Mesoamerica's formative period, dating roughly from as early as 1500 BCE to about 400 BCE. Pre-Olmec cultures had flourished since about 2500 BCE, but by 1600–1500 BCE, early Olmec culture had emerged, centered on the San Lorenzo Tenochtitlán site near the coast in southeast Veracruz. They were the first Mesoamerican civilization, and laid many of the foundations for the civilizations that followed. Among other "firsts", the Olmec appeared to practice ritual bloodletting and played the Mesoamerican ballgame, hallmarks of nearly all subsequent Mesoamerican societies. The aspect of the Olmecs most familiar now ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
