İzmit Bay Bridge
The Osman Gazi Bridge () is a suspension bridge spanning the Gulf of İzmit at its narrowest point, . The bridge links the Turkish city of Gebze to the Yalova Province and carries the O-5 motorway across the gulf. The bridge was opened on 1 July 2016 to become the then-longest suspension bridge in Turkey and the fourth-longest (ninth-longest as of 2025) suspension bridge in the world by the length of its central span. The length of the bridge was surpassed by the Çanakkale 1915 Bridge across the Dardanelles strait, which became the longest suspension bridge in the world when it was opened on 18 March 2022. Project Construction and operation of the bridge was awarded to a joint venture (NOMAYG JV) formed by five Turkish companies ( Nurol, Özaltın, Makyol, Yüksel and Gocay) and one Italian construction company Astaldi following the international Build–operate–transfer tender that took place in April 2009. In 2010, a contract was signed for the project that was estimate ...

Wire Rope
Steel wire rope (right hand lang lay) Wire rope is composed of as few as two solid, metal wires twisted into a helix that forms a composite ''rope'', in a pattern known as ''laid rope''. Larger diameter wire rope consists of multiple strands of such laid rope in a pattern known as ''cable laid''. Manufactured using an industrial machine known as a strander, the wires are fed through a series of barrels and spun into their final composite orientation. In stricter senses, the term ''wire rope'' refers to a diameter larger than , with smaller gauges designated cable or cords. Initially wrought iron wires were used, but today steel is the main material used for wire ropes. Historically, wire rope evolved from wrought iron chains, which had a record of mechanical failure. While flaws in chain links or solid steel bars can lead to catastrophic failure A catastrophic failure is a sudden and total failure from which recovery is impossible. Catastrophic failures often lead to cascadi ...

Footbridge
A footbridge (also a pedestrian bridge, pedestrian overpass, or pedestrian overcrossing) is a bridge designed solely for pedestrians.''Oxford English Dictionary'' While the primary meaning for a bridge is a structure which links "two points at a height above the ground", a footbridge can also be a lower structure, such as a boardwalk, that enables pedestrians to cross wet, fragile, or marshy land. Bridges range from stepping stones–possibly the earliest man-made structure to "bridge" water–to elaborate steel structures. Another early bridge would have been simply a fallen tree. In some cases a footbridge can be both functional and artistic. For rural communities in the developing world, a footbridge may be a community's only access to medical clinics, schools, businesses and markets. Simple suspension bridge designs have been developed to be Sustainability, sustainable and easily constructed in such areas using only local materials and labor. An enclosed footbridge between t ...

List Of Longest Suspension Bridges
The world's longest suspension bridges are listed according to the length of their main span (architecture), span (i.e., the length of suspended roadway between the bridge's towers). The length of the main span is the most common method of comparing the sizes of suspension bridges, often correlating with the height of the towers and the engineering complexity involved in designing and constructing the bridge. If one bridge has a longer span than another, it does not necessarily mean that the bridge is longer from shore to shore (or from abutment to abutment). Suspension bridges have the longest spans of any type of bridge. Cable-stayed bridges, the next longest design, are practical for spans up to just over 1 kilometre (the Russky Bridge, longest cable-stayed bridge in the world has a 1,104m span). Therefore, as of January 2025, the 33 longest bridges on this list are the 33 longest spans of all types of vehicular bridges (other than floating pontoon bridges). The 1915 Çanakk ...

Galați Steel Works
The Galați steel works (), formally Liberty Galați (formerly known as ''ArcelorMittal Galați'' and ''Sidex Galați''), is a steel mill in Galați, Romania, the country's largest. History Background The idea of building a large steel works in eastern Romania, with access to the Danube and/or the Black Sea, was first discussed in 1958 at a plenary session of the ruling Romanian Workers' Party. The decision was formalized by a decree in July 1960, shortly after the party's 8th Congress approved a huge investment for the project. At the congress, a heated debate took place over where to situate the plant; some wanted it near Constanța, at Midia or Mangalia, but they were overruled by leader Gheorghe Gheorghiu-Dej, who had roots in Galați. Building the works went against the wishes of the Soviet Union, whose leader Nikita Khrushchev, supported by the more industrialized Czechoslovakia and East Germany East Germany, officially known as the German Democratic Republic (GDR), ...

High-speed Railway
High-speed rail (HSR) is a type of rail transport network utilising trains that run significantly faster than those of traditional rail, using an integrated system of specialised rolling stock and dedicated railway track, tracks. While there is no single definition or standard that applies worldwide, lines built to handle speeds of at least or upgraded lines of at least are generally considered to be high-speed. The first high-speed rail system, the Tōkaidō Shinkansen, began operations in Honshu, Japan, in 1964. Due to the streamlined spitzer (bullet), spitzer-shaped nose cone of the 0 Series Shinkansen, trains, the system also became known by its English nickname bullet train. Japan's example was followed by several European countries, initially in High-speed rail in Italy, Italy with the Florence–Rome high-speed railway, Direttissima line, followed shortly thereafter by High-speed rail in France, France, High-speed rail in Germany, Germany, and High-speed rail in Spain, ...
