Stan Musial Veterans Memorial Bridge
The Stan Musial Veterans Memorial Bridge (known as the New Mississippi River Bridge until its formal naming in 2013 and informally known as the "Stan Span") is a bridge across the Mississippi River in the United States between St. Clair County, Illinois, and the city of St. Louis, Missouri. Built between April 19, 2010, and July 2013, the bridge opened on February 9, 2014. The cable-stayed bridge has a main span of 1,500 feet (457 m). Features The main span of the bridge is in length, part of a total span of . It is wide. Cables stretch from the bridge deck to the tops of two A-shaped towers, which reach above I-70. The new bridge's main span is supported by of stay-cable strand, enough for nearly two round trips from St. Louis to Chicago. Nearly 15,000 tons of structural steel are used, along with 8,600 tons of reinforcing steel. Some of concrete are in the foundation, deck slab, and towers. At its completion, the bridge was the third-longest cable-stayed bridge in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mississippi River
The Mississippi River is the second-longest river and chief river of the second-largest drainage system in North America, second only to the Hudson Bay drainage system. From its traditional source of Lake Itasca in northern Minnesota, it flows generally south for to the Mississippi River Delta in the Gulf of Mexico. With its many tributaries, the Mississippi's watershed drains all or parts of 32 U.S. states and two Canadian provinces between the Rocky and Appalachian mountains. The main stem is entirely within the United States; the total drainage basin is , of which only about one percent is in Canada. The Mississippi ranks as the thirteenth-largest river by discharge in the world. The river either borders or passes through the states of Minnesota, Wisconsin, Iowa, Illinois, Missouri, Kentucky, Tennessee, Arkansas, Mississippi, and Louisiana. Native Americans have lived along the Mississippi River and its tributaries for thousands of years. Most were hunter-ga ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Interstate 70 In Missouri
Interstate 70 (I-70) in the US state of Missouri is generally parallel to the Missouri River. This section of the transcontinental Interstate begins at the Kansas state line on the Lewis and Clark Viaduct, running concurrently with U.S. Route 24 (US 24), US 40, and US 169, and the east end is on the Stan Musial Veterans Memorial Bridge in St. Louis. Route description Crossing into Missouri on the Lewis and Clark Viaduct, I-70 immediately encounters the Alphabet Loop, a small but complex loop of freeways with all of its exits having the number 2 and a letter suffix that uses the entire alphabet (except I, O, and Z). I-70 runs concurrently with I-35 once it enters into the Loop. Both Interstates maintain the concurrency until they approach the northeastern corner of the Loop. Back at the northwest corner, US 169 splits off to the north, leaving four routes concurrent with each other. There is a large interchange with Route 9 in th ...

Limestone
Limestone ( calcium carbonate ) is a type of carbonate sedimentary rock which is the main source of the material lime. It is composed mostly of the minerals calcite and aragonite, which are different crystal forms of . Limestone forms when these minerals precipitate out of water containing dissolved calcium. This can take place through both biological and nonbiological processes, though biological processes, such as the accumulation of corals and shells in the sea, have likely been more important for the last 540 million years. Limestone often contains fossils which provide scientists with information on ancient environments and on the evolution of life. About 20% to 25% of sedimentary rock is carbonate rock, and most of this is limestone. The remaining carbonate rock is mostly dolomite, a closely related rock, which contains a high percentage of the mineral dolomite, . ''Magnesian limestone'' is an obsolete and poorly-defined term used variously for dolomite, for limes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Earthquake
An earthquake (also known as a quake, tremor or temblor) is the shaking of the surface of the Earth resulting from a sudden release of energy in the Earth's lithosphere that creates seismic waves. Earthquakes can range in intensity, from those that are so weak that they cannot be felt, to those violent enough to propel objects and people into the air, damage critical infrastructure, and wreak destruction across entire cities. The seismic activity of an area is the frequency, type, and size of earthquakes experienced over a particular time period. The seismicity at a particular location in the Earth is the average rate of seismic energy release per unit volume. The word ''tremor'' is also used for Episodic tremor and slip, non-earthquake seismic rumbling. At the Earth's surface, earthquakes manifest themselves by shaking and displacing or disrupting the ground. When the epicenter of a large earthquake is located offshore, the seabed may be displaced sufficiently to cause ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Liquefaction
In materials science, liquefaction is a process that generates a liquid from a solid or a gas or that generates a non-liquid phase which behaves in accordance with fluid dynamics. It occurs both naturally and artificially. As an example of the latter, a "major commercial application of liquefaction is the liquefaction of air to allow separation of the constituents, such as oxygen, nitrogen, and the noble gases." Another is the conversion of solid coal into a liquid form usable as a substitute for liquid fuels. Geology In geology, soil liquefaction refers to the process by which water-saturated, unconsolidated sediments are transformed into a substance that acts like a liquid, often in an earthquake. Soil liquefaction was blamed for building collapses in the city of Palu, Indonesia in October 2018. In a related phenomenon, liquefaction of bulk materials in cargo ships may cause a dangerous shift in the load. Physics and chemistry In physics and chemistry, the phase transiti ...

Ralph Modjeski
Ralph Modjeski (born Rudolf Modrzejewski; January 27, 1861 – June 26, 1940) was a Polish-American civil engineer who achieved prominence as "America's greatest bridge builder." Life He was born in Bochnia, called Galicia at the time, on January 27, 1861, to Gustav Sinnmayer Modrzejewski and actress Helena Opid Modrzejewska (best known outside Poland as Helena Modjeska). In 1865, his mother left Sinnmayer, and in 1868, she married "Count" Karol Bożenta Chłapowski. In July 1876, they emigrated to America, where, as a matter of convenience, the boy's mother changed her name to Helena Modjeska and her son's name to Ralph Modjeski. He was a classmate of Ignacy Jan Paderewski in Poland and was a formidable pianist in his own right. The son returned to Europe to study at ''l'Ecole des Ponts et Chaussées'' (the School of Bridges and Roads) in Paris, France. It was in 1883, while studying at Paris, that he obtained American citizenship. However, he always maintained contact with ...

Engineering
Engineering is the use of scientific method, scientific principles to design and build machines, structures, and other items, including bridges, tunnels, roads, vehicles, and buildings. The discipline of engineering encompasses a broad range of more specialized List of engineering branches, fields of engineering, each with a more specific emphasis on particular areas of applied mathematics, applied science, and types of application. See glossary of engineering. The term ''engineering'' is derived from the Latin ''ingenium'', meaning "cleverness" and ''ingeniare'', meaning "to contrive, devise". Definition The American Engineers' Council for Professional Development (ECPD, the predecessor of Accreditation Board for Engineering and Technology, ABET) has defined "engineering" as: The creative application of scientific principles to design or develop structures, machines, apparatus, or manufacturing processes, or works utilizing them singly or in combination; or to construct o ...

Interstate 44 (I-44) in the US state of Missouri runs northeast from the Oklahoma state line near Joplin to I-70 in Downtown St. Louis. It runs for about in the state, and is the longest Interstate Highway in the state. Route description I-44 enters Missouri in Newton County at the eastern terminus of the Will Rogers Turnpike, south of the Kansas state line. The first interchange in Missouri is the eastern terminus of both U.S. Route 166 (US 166) and US 400. This highway next goes through southern Joplin and then begins to run concurrently with I-49/ US 71 at exit 11 just after entering Jasper County.

East St
East or Orient is one of the four cardinal directions or points of the compass. It is the opposite direction from west and is the direction from which the Sun rises on the Earth. Etymology As in other languages, the word is formed from the fact that east is the direction where the Sun rises: ''east'' comes from Middle English ''est'', from Old English ''ēast'', which itself comes from the Proto-Germanic *''aus-to-'' or *''austra-'' "east, toward the sunrise", from Proto-Indo-European *aus- "to shine," or "dawn", cognate with Old High German ''*ōstar'' "to the east", Latin ''aurora'' 'dawn', and Greek ''ēōs'' 'dawn, east'. Examples of the same formation in other languages include Latin oriens 'east, sunrise' from orior 'to rise, to originate', Greek ανατολή anatolé 'east' from ἀνατέλλω 'to rise' and Hebrew מִזְרָח mizraḥ 'east' from זָרַח zaraḥ 'to rise, to shine'. ''Ēostre'', a Germanic goddess of dawn, might have been a personificatio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
