Triangle Link
The Triangle Link ( no, Trekantsambandet) is a fixed link with three branches that connects the islands of Stord and Bømlo to each other and to the mainland at Sveio, Norway. It consists of the underwater Bømlafjord Tunnel from Sveio to the island of Føyno, the Stord Bridge from there to Stord, and a road including the Bømla Bridge and the Spissøy Bridge to Bømlo. The section from Sveio to Stord is part of European Route E39, while the branch to Bømlo is part of County Road 542. The Bømlo Tunnel is long and reaches below mean sea level. It is the longest subsea tunnel in Norway and was the deepest in the world when it opened. The Stord Bridge and Bømla Bridge are both suspension bridges, with lengths of and main spans of . The Spissøy Bridge is a beam bridge. The link is long toll road with a toll plaza on Føyno. The section from Stord to Bømlo has a pedestrian and bicycle path. Plans for a link between Bømlo and Stord were first launched as a pontoon ...

Stord Bridge (Stordabruo)-edit
The Stord Bridge ( no, Stordabrua) is a suspension bridge which crosses Digernessundet between the islands of Stord and Føyno in Stord Municipality in Vestland county, Norway. The bridge is long, has a main span of and a clearance below of . It carries two lanes of European Route E39 and a combined pedestrian and bicycle pathway. It is part of the Triangle Link, a fixed link which connects Stord to Bømlo, and both to the mainland. In 2010, the bridge had an average 5,021 vehicles per day. The bridge and the link was a toll road from the opening until 30 May 2013. Plans for a crossing arose in the 1960s; and until the 1990s proposals were for a pontoon bridge further north. The Stord Bridge was conceived after the decision to combine the crossing with the Bømlafjord Tunnel. The project was resisted both by local environmental groups and the Norwegian Public Roads Administration, the latter because the new plans would delay completion. Construction was undertaken by a joint ve ...

Toll Plaza
A toll road, also known as a turnpike or tollway, is a public or private road (almost always a controlled-access highway in the present day) for which a fee (or ''toll'') is assessed for passage. It is a form of road pricing typically implemented to help recoup the costs of road construction and maintenance. Toll roads have existed in some form since antiquity, with tolls levied on passing travelers on foot, wagon, or horseback; a practice that continued with the automobile, and many modern tollways charge fees for motor vehicles exclusively. The amount of the toll usually varies by vehicle type, weight, or number of axles, with freight trucks often charged higher rates than cars. Tolls are often collected at toll plazas, toll booths, toll houses, toll stations, toll bars, toll barriers, or toll gates. Some toll collection points are automatic, and the user deposits money in a machine which opens the gate once the correct toll has been paid. To cut costs and minimise time delay, ...

Grade Separated
In civil engineering (more specifically highway engineering), grade separation is a method of aligning a junction of two or more surface transport axes at different heights (grades) so that they will not disrupt the traffic flow on other transit routes when they cross each other. The composition of such transport axes does not have to be uniform; it can consist of a mixture of roads, footpaths, railways, canals, or airport runways. Bridges (or overpasses, also called flyovers), tunnels (or underpasses), or a combination of both can be built at a junction to achieve the needed grade separation. In North America, a grade-separated junction may be referred to as a ''grade separation'' or as an '' interchange'' – in contrast with an ''intersection'', ''at-grade'', a '' diamond crossing'' or a ''level crossing'', which are not grade-separated. Effects Advantages Roads with grade separation generally allow traffic to move freely, with fewer interruptions, and at higher overall s ...

Triangle Link Map Upload
A triangle is a polygon with three Edge (geometry), edges and three Vertex (geometry), vertices. It is one of the basic shapes in geometry. A triangle with vertices ''A'', ''B'', and ''C'' is denoted \triangle ABC. In Euclidean geometry, any three points, when non-Collinearity, collinear, determine a unique triangle and simultaneously, a unique Plane (mathematics), plane (i.e. a two-dimensional Euclidean space). In other words, there is only one plane that contains that triangle, and every triangle is contained in some plane. If the entire geometry is only the Euclidean plane, there is only one plane and all triangles are contained in it; however, in higher-dimensional Euclidean spaces, this is no longer true. This article is about triangles in Euclidean geometry, and in particular, the Euclidean plane, except where otherwise noted. Types of triangle The terminology for categorizing triangles is more than two thousand years old, having been defined on the very first page of ...

Askøy Bridge
The Askøy Bridge ( no, Askøybroen) is a suspension bridge that crosses the Byfjorden between the municipalities of Bergen and Askøy in Vestland county, Norway. It is long and has a main span of . Its span was the longest for any suspension bridge in Norway, until the Hardanger Bridge was opened in August 2013. Now the bridge is the third longest in Norway. It carries two lanes of County Road 562 and a combined pedestrian and bicycle path. The bridge's two concrete pylons are tall and are located at Brøstadneset in Bergen municipality (on the Bergen Peninsula of the mainland) and Storeklubben in Askøy municipality (on the island of Askøy). The bridge has seven spans in total, although all but the main span are concrete viaducts. The bridge has a clearance below of . The first plans to replace the Kleppestø–Nøstet Ferry with a bridge, which would allow the island of Askøy to have a fixed link, was launched in the 1960s. Various proposals were made, including placin ...

Tower
A tower is a tall Nonbuilding structure, structure, taller than it is wide, often by a significant factor. Towers are distinguished from guyed mast, masts by their lack of guy-wires and are therefore, along with tall buildings, self-supporting structures. Towers are specifically distinguished from buildings in that they are built not to be habitable but to serve other functions using the height of the tower. For example, the height of a clock tower improves the visibility of the clock, and the height of a tower in a fortified building such as a castle increases the visibility of the surroundings for defensive purposes. Towers may also be built for observation tower, observation, leisure, or telecommunication purposes. A tower can stand alone or be supported by adjacent buildings, or it may be a feature on top of a larger structure or building. Etymology Old English ''torr'' is from Latin ''turris'' via Old French ''tor''. The Latin term together with Greek language, Greek τύ ...

Mean Sea Level
There are several kinds of mean in mathematics Mathematics is an area of knowledge that includes the topics of numbers, formulas and related structures, shapes and the spaces in which they are contained, and quantities and their changes. These topics are represented in modern mathematics ..., especially in statistics. Each mean serves to summarize a given group of data, often to better understand the overall value (magnitude (mathematics), magnitude and sign (mathematics), sign) of a given data set. For a data set, the ''arithmetic mean'', also known as "arithmetic average", is a measure of central tendency of a finite set of numbers: specifically, the sum of the values divided by the number of values. The arithmetic mean of a set of numbers ''x''1, ''x''2, ..., x''n'' is typically denoted using an overhead bar, \bar. If the data set were based on a series of observations obtained by sampling (statistics), sampling from a statistical population, the arithmetic mean is th ...

Bømlafjorden
Bømlafjorden ( en, Bømla Fjord) is a fjord in Vestland county, Norway. The fjord is the outer-most part of the Hardangerfjord, running between the island of Bømlo (in Bømlo Municipality) and the mainland (Sveio Municipality). The Bømlafjord Tunnel crosses under Bømlafjorden. History King Magnus IV of Sweden and Norway drowned in a shipwreck in the fjord in 1374. On February 21, 1945, the vessel ''D/S Austri'' was attacked by British aircraft and sunk in the fjord. The passengers included German military personnel, prisoners of war, and civilian passengers, among them the judge and newspaperman Gerhard Jynge Gerhard Vilhelm Jynge (1877 – February 21, 1945) was a Norwegian newspaper editor.

Subsea Tunnel
An underwater tunnel is a tunnel which is partly or wholly constructed under the sea or a river. They are often used where building a bridge or operating a ferry link is unviable, or to provide competition or relief for existing bridges or ferry links.Sullivan, WalterProgress In Technology Revives Interest In Great Tunnels New York Times, June 24, 1986. Retrieved 15 August 2010. While short tunnels are often road tunnels which may admit motorized traffic, unmotorized traffic or both, concerns with ventilation lead to the longest tunnels (such as the Channel Tunnel or the Seikan Tunnel) being electrified rail tunnels. Types of tunnel Various methods are used to construct underwater tunnels, including an immersed tube and a submerged floating tunnel. The immersed tube method involves steel tube segments that are positioned in a trench in the sea floor and joined together. The trench is then covered and the water pumped from the tunnel. Submerged floating tunnels use the law of buoya ...

Cost Overrun
A cost overrun, also known as a cost increase or budget overrun, involves unexpected incurred costs. When these costs are in excess of budgeted amounts due to a value engineering underestimation of the actual cost during budgeting, they are known by these terms. Cost overruns are common in infrastructure, building, and technology projects. For IT projects, a 2004 industry study by the Standish Group found an average cost overrun of 43 percent; 71 percent of projects came in over budget, exceeded time estimates, and had estimated too narrow a scope; and total waste was estimated at $55 billion per year in the US alone. Many major construction projects have incurred cost overruns; cost estimates used to decide whether important transportation infrastructure should be built can mislead grossly and systematically. Cost overrun is distinguished from cost escalation, which is an ''anticipated'' growth in a budgeted cost due to factors such as inflation. Causes Recent works by Ahia ...
