Frisco Bridge
The Frisco Bridge, previously known as the Memphis Bridge, is a cantilevered through truss bridge carrying a rail line across the Mississippi River between West Memphis, Arkansas, and Memphis, Tennessee. Construction At the time of the Memphis bridge construction, it was a significant technological challenge and is considered to be chief engineer George S. Morison's crowning achievement. No other bridges had ever been attempted on the Lower Mississippi River. The bridge is built entirely of open-hearth steel, a newly developed material at the time of construction. The structure features a main span and two additional spans. Its height above the water was the highest clearance of any U.S. bridge of that era. The construction of the piers went nearly below the water's surface. Though some sources claim two cantilevered roadways were added to the bridge in the 1930s, one on each side, they probably confuse this bridge with the neighboring Harahan Bridge, which had two c ...

Memphis & Arkansas Bridge
The Memphis & Arkansas Bridge, also known as the Memphis–Arkansas Bridge or inaccurately as the Memphis–Arkansas Memorial Bridge, is a cantilevered through truss bridge carrying Interstate 55 across the Mississippi River between West Memphis, Arkansas and Memphis, Tennessee. Memphians refer to this bridge as the "Old Bridge" to distinguish it from the "New Bridge", or Hernando de Soto Bridge, upstream. The Memphis & Arkansas Bridge also carries U.S. Route 61 (US 61), US 64, US 70, US 78, and US 79 from Memphis to West Memphis; it also carried US 63 prior to its truncation (and later rerouting) in Arkansas. The western terminus of Tennessee State Route 1 (SR 1) sits on the Tennessee–Arkansas boundary halfway across the bridge. Opened in 1949, the bridge is currently the oldest bridge on the Interstate Highway System in Tennessee and Arkansas. It is currently planned to be replaced with a larger and wider bridge, starting in 2026. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Bridges Over The Mississippi River
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] |

Truss Bridges In The United States
A truss is an assembly of ''members'' such as beams, connected by ''nodes'', that creates a rigid structure. In engineering, a truss is a structure that "consists of two-force members only, where the members are organized so that the assemblage as a whole behaves as a single object". A ''two-force member'' is a structural component where force is applied to only two points. Although this rigorous definition allows the members to have any shape connected in any stable configuration, architectural trusses typically comprise five or more triangular units constructed with straight members whose ends are connected at joints referred to as '' nodes''. In this typical context, external forces and reactions to those forces are considered to act only at the nodes and result in forces in the members that are either tensile or compressive. For straight members, moments (torques) are explicitly excluded because, and only because, all the joints in a truss are treated as revolutes, as ...

US 79
U.S. Route 79 (US 79) is a United States highway in the Southern United States. The route is officially considered and signed as a north–south highway, but its path is actually more of a diagonal northeast–southwest highway. The highway's northern/eastern terminus is in Russellville, Kentucky, at a junction with U.S. 68. Its southern/western terminus is in Round Rock, Texas, at an interchange with Interstate 35, north of Austin. US 79, US 68, and Interstate 24/US 62 are the primary east–west access points for the Land Between the Lakes recreation area straddling the Kentucky/Tennessee border. Route description Texas US 79 begins at Interstate 35's Exit #253 north of Austin in Round Rock. The route travels eastward through Hutto and Taylor to Rockdale, where it intersects US 77. In Milano, US 79 turns to the northeast and begins a concurrency with US 190 until Hearne. The route continues through Franklin and Jewett before reaching Buffalo, where it intersec ...

US 70
U.S. Route 70 or U.S. Highway 70 (US 70) is an east–west United States highway that runs for from eastern North Carolina to east-central Arizona. It is a major east–west highway of the Southeastern, Southern and Southwestern United States. Established as one of the original highways of 1926, it originally ran only to Holbrook, Arizona, then was extended in 1934 as a coast to coast route, with the current eastern terminus near the Atlantic Ocean in Atlantic, North Carolina, and the former western terminus near the Pacific Ocean in Los Angeles, California. Its western end was truncated to Blythe, California in 1963, and was again truncated to US 60 / SR 77 in Globe, Arizona in 1969. Before the completion of the Interstate Highway system, U.S. Highway 70 was sometimes referred to as the "Broadway of America", due to its status as one of the main east–west thoroughfares in the nation. It was also promoted as the "Treasure Trail" by the U.S. Highway 70 Association as of 1951. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

US 61
U.S. Route 61 or U.S. Highway 61 (U.S. 61) is a major United States highway that extends between New Orleans, Louisiana and the city of Wyoming, Minnesota. The highway generally follows the course of the Mississippi River and is designated the Great River Road for much of its route. As of 2004, the highway's northern terminus in Wyoming, Minnesota, is at an intersection with Interstate 35 (I-35). Until 1991, the highway extended north on what is now Minnesota State Highway 61 (MN 61) through Duluth to the Canada–U.S. border near Grand Portage, then continued to Thunder Bay, Canada, as Ontario Highway 61. Its southern terminus in New Orleans is at an intersection with U.S. Route 90 (US 90). The route was an important south–north connection in the days before the interstate highway system. The highway is often called the Blues Highway because of its long history in blues music; part of the route lies on the Mississippi Blues Trail and is denoted by markers in Vicksb ...

I-55
Interstate 55 (I-55) is a major Interstate Highway in the central United States. As with most primary Interstates that end in a five, it is a major cross-country, north–south route, connecting the Gulf of Mexico to the Great Lakes. The highway travels from LaPlace, Louisiana, at I-10 to Chicago, Illinois, at Lake Shore Drive (US 41), near McCormick Place. The major cities that I-55 connects to are (from south to north) New Orleans, Louisiana; Jackson, Mississippi; Memphis, Tennessee; St. Louis, Missouri; and Chicago, Illinois. The section of I-55 between Chicago and St. Louis was built as an alternate route for U.S. Route 66 (US 66). The Interstate crosses the Mississippi River twice: once at Memphis and again at St. Louis. History When it was realized that a national highway system was needed, the Federal Aid Highway Act of 1956 provided for a highway replacing the old US 66 which I-55 filled. I-55 was originally constructed in the 1960s, to extend a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
