Asparuhov Bridge
The Asparuhov most ( bg, Аспарухов мост) or Asparuhov Bridge is a bridge in Varna on the Black Sea coast of Bulgaria. It connects the Asparuhovo district to the rest of the city over the canals between the Black Sea and Lake Varna. The bridge is 2.05 km in length and 50 m in height, weighing 3,200 tons. It has 38 pairs of supports, each one capable of carrying 2,400 tons. The bridge experiences significant traffic, with 10,000 vehicles crossing it every day. The bridge's construction began in 1973 when the need for a larger canal to link Lake Varna and the sea became necessary. The initial launch date was set for 30 September 1976, but construction was ahead of schedule and finished on 8 September, when the bridge was opened in a ceremony by Todor Zhivkov. Meanwhile, the new canal that the bridge crosses began operation on 1 September, with the first ship going through on 4 September of the same year. After 20 years of neglect, reconstruction work began in 199 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Extreme Sports
Action sports, adventure sports or extreme sports are activities perceived as involving a high degree of risk. These activities often involve speed, height, a high level of physical exertion and highly specialized gear. Extreme tourism overlaps with extreme sport. The two share the same main attraction, " adrenaline rush" caused by an element of risk, and differ mostly in the degree of engagement and professionalism. Definition The definition of extreme sports is not exact and the origin of the terms is unclear, but it gained popularity in the 1990s when it was picked up by marketing companies to promote the X Games and when the Extreme Sports Channel and Extreme International launched. More recently, the commonly used definition from research is "a competitive (comparison or self-evaluative) activity within which the participant is subjected to natural or unusual physical and mental challenges such as speed, height, depth or natural forces and where fast and accurate cogniti ...

Bridges Completed In 1976
A bridge is a structure built to span a physical obstacle (such as a body of water, valley, road, or rail) without blocking the way 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, and 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 still in existence and use.

Cantilever Bridges
A cantilever bridge is a bridge built using structures that project horizontally into space, supported on only one end (called cantilevers). For small footbridges, the cantilevers may be simple beams; however, large cantilever bridges designed to handle road or rail traffic use trusses built from structural steel Structural steel is a category of steel used for making construction materials in a variety of shapes. Many structural steel shapes take the form of an elongated beam having a profile of a specific cross section. Structural steel shapes, sizes, ..., or box girders built from prestressed concrete. The steel truss cantilever bridge was a major engineering breakthrough when first put into practice, as it can span distances of over , and can be more easily constructed at difficult crossings by virtue of using little or no falsework. Origins Civil engineer, Engineers in the 19th century understood that a bridge that was continuous across multiple supports would dis ...

Buildings And Structures In Varna, Bulgaria
A building, or edifice, is an enclosed structure with a roof and walls standing more or less permanently in one place, such as a house or factory (although there's also portable buildings). Buildings come in a variety of sizes, shapes, and functions, and have been adapted throughout history for a wide number of factors, from building materials available, to weather conditions, land prices, ground conditions, specific uses, prestige, and aesthetic reasons. To better understand the term ''building'' compare the list of nonbuilding structures. Buildings serve several societal needs – primarily as shelter from weather, security, living space, privacy, to store belongings, and to comfortably live and work. A building as a shelter represents a physical division of the human habitat (a place of comfort and safety) and the ''outside'' (a place that at times may be harsh and harmful). Ever since the first cave paintings, buildings have also become objects or canvasses of much artis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cycle Track
A cycle track, separated bike lane or protected bike lane (sometimes historically referred to as a sidepath) is an exclusive bikeway that has elements of a separated path and on-road bike lane. A cycle track is located within or next to the roadway, but is made distinct from both the sidewalk and general purpose roadway by vertical barriers or elevation differences. In urban planning, cycle tracks are designed to encourage bicycling in an effort to relieve automobile congestion and reduce pollution, reduce bicycling fatalities and injuries by eliminating the need for cars and bicycles to jockey for the same road space, and to reduce overall confusion and tension for all users of the road. Cycle tracks may be one-way or two-way, and may be at road level, at sidewalk level, or at an intermediate level. They all have in common some separation from motor traffic with bollards, car parking, barriers or boulevards. Barriers may include curbs, concrete berms, posts, planting/median ...

Suicide Bridge
A suicide bridge is a bridge used frequently by people to end their lives, most typically by jumping off and into the water or ground below. A fall from the height of a tall bridge into water may be fatal, although some people have survived jumps from high bridges such as the Golden Gate Bridge. However, significant injury or death is far from certain; numerous studies report minimally injured persons who died from drowning.Stephanian, D. , url = https://dx.doi.org/10.14288/1.0387208 , title = Outcomes in suicidal bridge jumping in the Lower Mainland , date = December, 2019 To reach such locations, those with the intention of ending their lives must often walk long distances to reach the point where they finally decide to jump. For example, some individuals have traveled over the San Francisco–Oakland Bay Bridge by car in order to jump from the Golden Gate Bridge.

Bungee Jumping
Bungee jumping (), also spelled bungy jumping, is an activity that involves a person jumping from a great height while connected to a large elastic cord. The launching pad is usually erected on a tall structure such as a building or crane, a bridge across a deep ravine, or on a natural geographic feature such as a cliff. It is also possible to jump from a type of aircraft that has the ability to hover above the ground, such as a hot-air-balloon or helicopter. The thrill comes from the free-falling and the rebound. When the person jumps, the cord stretches and the jumper flies upwards again as the cord recoils, and continues to oscillate up and down until all the kinetic energy is dissipated. Early tethered jumping The land diving ( Sa: ') of Pentecost Island in Vanuatu is an ancient ritual in which young men jump from tall wooden platforms with vines tied to their ankles as a test of their courage and passage into manhood. Unlike in modern bungee-jumping, land-divers in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Bulgaria
Bulgaria (; bg, България, Bǎlgariya), officially the Republic of Bulgaria,, ) is a country in Southeast Europe. It is situated on the eastern flank of the Balkans, and is bordered by Romania to the north, Serbia and North Macedonia to the west, Greece and Turkey to the south, and the Black Sea to the east. Bulgaria covers a territory of , and is the sixteenth-largest country in Europe. Sofia is the nation's capital and largest city; other major cities are Plovdiv, Varna and Burgas. One of the earliest societies in the lands of modern-day Bulgaria was the Neolithic Karanovo culture, which dates back to 6,500 BC. In the 6th to 3rd century BC the region was a battleground for ancient Thracians, Persians, Celts and Macedonians; stability came when the Roman Empire conquered the region in AD 45. After the Roman state splintered, tribal invasions in the region resumed. Around the 6th century, these territories were settled by the early Slavs. The Bulgars, led by Asp ...

Traffic
Traffic comprises pedestrians, vehicles, ridden or herded animals, trains, and other conveyances that use public ways (roads) for travel and transportation. Traffic laws govern and regulate traffic, while rules of the road include traffic laws and informal rules that may have developed over time to facilitate the orderly and timely flow of traffic. Organized traffic generally has well-established priorities, lanes, right-of-way, and traffic control at intersections. Traffic is formally organized in many jurisdictions, with marked lanes, junctions, intersections, interchanges, traffic signals, or signs. Traffic is often classified by type: heavy motor vehicle (e.g., car, truck), other vehicle (e.g., moped, bicycle), and pedestrian. Different classes may share speed limits and easement, or may be segregated. Some jurisdictions may have very detailed and complex rules of the road while others rely more on drivers' common sense and willingness to cooperate. Organization ...
