Quincy Rail Bridge
The Quincy Rail Bridge is a truss bridge that carries a rail line across the Mississippi River between West Quincy, Missouri, and Quincy, Illinois, USA. It was originally constructed in 1868 for the Chicago, Burlington and Quincy Railroad, a predecessor of BNSF Railway. From the 1950s until 1971 it served the ''Kansas City Zephyr'' and ''American Royal Zephyr'' daily passenger trains between Chicago and Kansas City. It served Amtrak's ''Illinois Zephyr'' from Chicago to West Quincy, Missouri, from 1971 to 1993. Since the Great Flood of 1993 the Amtrak ''Illinois Zephyr'' and ''Carl Sandburg (Amtrak), Carl Sandburg'' services terminate at the Quincy (Amtrak station), Quincy station, although after the passengers have disembarked the trains do cross the bridge to the BNSF Railway Rail yard, yard in West Quincy, where the equipment is oriented in the proper direction for the return trip on the Wye (railroad), wye and is stored until the next departure.

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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Through-truss
A truss bridge is a bridge whose load-bearing superstructure is composed of a truss, a structure of connected elements, usually forming triangular units. The connected elements (typically straight) may be stressed from tension, compression, or sometimes both in response to dynamic loads. The basic types of truss bridges shown in this article have simple designs which could be easily analyzed by 19th and early 20th-century engineers. A truss bridge is economical to construct because it uses materials efficiently. Design The nature of a truss allows the analysis of its structure using a few assumptions and the application of Newton's laws of motion according to the branch of physics known as statics. For purposes of analysis, trusses are assumed to be pin jointed where the straight components meet, meaning that taken alone, every joint on the structure is functionally considered to be a flexible joint as opposed to a rigid joint with strength to maintain its own shape, and th ...

US 24
U.S. Route 24 (US 24) is one of the original United States highways of 1926. It originally ran from Pontiac, Michigan, in the east to Kansas City, Missouri, in the west. Today, the highway's eastern terminus is in Independence Township, Michigan at an intersection with I-75, and its western terminus is near Minturn, Colorado at an intersection with I-70. The highway transitions from north–south to east–west signage at the Ohio-Michigan state line. Route description Colorado In Colorado, US 24 begins at the interchange of I-70 and US 6 (Exit 171) near Minturn. From this interchange, US 24 proceeds southeast through Minturn and continues south to the Continental Divide at Tennessee Pass. It continues south to Johnson Village and then joins with US 285 northbound to the Trout Creek Pass. After the pass, US 24 separates from US 285 and continues east to Colorado Springs and then northeast to Limon, where US 24 joins I-70 ...

Bayview Bridge
The Bayview Bridge is a cable-stayed bridge bringing westbound U.S. Route 24 (US 24) over the Mississippi River. It connects the cities of West Quincy, Missouri and Quincy, Illinois. Quincy Memorial Bridge serves Eastbound US-24. The bridge was built at a cost of $32 million, $3 million over budget. Rationale for construction During the 1980s, it was decided that the Quincy Memorial Bridge, though still structurally sound, was insufficient for traffic. Therefore, the Bayview Bridge was built to alleviate traffic over the older bridge. It was built before the extension of Interstate 72 (I-72) west into Hannibal, Missouri. Traffic levels increased when the existing downstream US 36 bridge over the Mississippi River was closed to make room for the new I-72 bridge.

US 136
U.S. Route 136 is an east-west U.S. highway that is a spur route of U.S. Route 36. It runs from Edison, Nebraska, at U.S. Route 6 and U.S. Route 34 to the Interstate 74/Interstate 465 interchange in Speedway, Indiana. This is a distance of . US 136 never meets its parent, US 36; however, it does come within two miles of it at its interchange with I-465/I-74 at its eastern terminus. Route description U.S. 136 passes through the following states: Nebraska U.S. 136 closely parallels Nebraska's southern border from its western terminus near Edison to the Missouri River. It passes through Beatrice and exits the state at Brownville via the Brownville Bridge. It is designated the Heritage Highway throughout Nebraska. Missouri US 136 enters Missouri on the west just east of Brownville, Nebraska, over the Missouri River. It leaves the state at Alexandria on the east, running concurrently with US 61. During its journey, it enters every county seat in the nine counti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Keokuk–Hamilton Bridge
The Keokuk-Hamilton bridge is a steel girder, 4-lane bridge from Keokuk, Iowa to Hamilton, Illinois. It carries U.S. Route 136 across the Mississippi River. It also has fully fenced off pedestrian walkway. The Keokuk–Hamilton Bridge was built in 1985, taking over automobile traffic from the Keokuk Rail Bridge (though the latter bridge still carries rail traffic). During the Great Flood of 1993, the rising Mississippi temporarily made the Keokuk–Hamilton Bridge inaccessible from the Illinois side of the river; later, gravel was layered over the threatened section of U.S. 136 to raise its level and keep the road and bridge accessible for the remaining flood period. More recently, during the 2008 Midwest floods, the Illinois access was again threatened, but this time gravel was applied and the road level raised before it was rendered completely impassable; only temporary closings were required to allow road workers to complete the job.

Junction (rail)
A junction, in the context of rail transport, is a place at which two or more rail routes converge or diverge. This implies a physical connection between the tracks of the two routes (assuming they are of the same gauge), provided by ''points'' (US: switches) and signalling. Junctions are important for rail systems, their installation into a rail system can expand route capacity, and have a powerful impact upon on-time performance. Overview In a simple case where two routes with one or two tracks each meet at a junction, a fairly simple layout of tracks suffices to allow trains to transfer from one route to the other. More complicated junctions are needed to permit trains to travel in either direction after joining the new route, for example by providing a triangular track layout. In this latter case, the three points of the triangle may be given different names, for example using points of the compass as well as the name of the overall place. Rail transport operations re ...

Quincy Memorial Bridge
The Quincy Memorial Bridge is a truss bridge over the Mississippi River in Quincy, Illinois. It brings eastbound U.S. Highway 24 into the city of Quincy from Missouri. It was built in 1930, initially as a toll bridge, and remains structurally sound. Building of the bridge began in 1928 by the Kelly-Atkinson Company. It was completed in 1930, with the first car crossing the bridge on May 19th of that year on an official inspection trip. The original toll for the bridge was 50 cents, by 1945 the city had paid the outstanding bonds which financed the bridge's construction, and the fares were eliminated. In 1986, to serve additional traffic volumes crossing the Mississippi River into Quincy, the Illinois Department of Transportation constructed the Bayview Bridge just to the north of the Memorial Bridge. Westbound traffic was then routed onto the Bayview Bridge, while eastbound traffic was routed onto the Memorial Bridge. Since 2012, demolition and replacement of the historic Memoria ...

Wrought Iron
Wrought iron is an iron alloy with a very low carbon content (less than 0.08%) in contrast to that of cast iron (2.1% to 4%). It is a semi-fused mass of iron with fibrous slag inclusions (up to 2% by weight), which give it a wood-like "grain" that is visible when it is etched, rusted, or bent to failure. Wrought iron is tough, malleable, ductile, corrosion resistant, and easily forge welded, but is more difficult to weld electrically. Before the development of effective methods of steelmaking and the availability of large quantities of steel, wrought iron was the most common form of malleable iron. It was given the name ''wrought'' because it was hammered, rolled, or otherwise worked while hot enough to expel molten slag. The modern functional equivalent of wrought iron is mild steel, also called low-carbon steel. Neither wrought iron nor mild steel contain enough carbon to be hardenable by heating and quenching. Wrought iron is highly refined, with a small amount of silic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Swing Bridge
A swing bridge (or swing span bridge) is a movable bridge that has as its primary structural support a vertical locating pin and support ring, usually at or near to its center of gravity, about which the swing span (turning span) can then pivot horizontally as shown in the animated illustration to the right. Small swing bridges as found over canals may be pivoted only at one end, opening as would a gate, but require substantial underground structure to support the pivot. In its closed position, a swing bridge carrying a road or railway over a river or canal, for example, allows traffic to cross. When a water vessel needs to pass the bridge, road traffic is stopped (usually by traffic signals and barriers), and then motors rotate the bridge horizontally about its pivot point. The typical swing bridge will rotate approximately 90 degrees, or one-quarter turn; however, a bridge which intersects the navigation channel at an oblique angle may be built to rotate only 45 degrees, o ...
