Kværner felt that the Public Roads Administration should bear the extra costs, demanding NOK 108 million in compensation, but the administration denied this, resulting in a lawsuit. Its E39 coastal highway, a … [2], The technology for the bridge was based on recent technology for pontoon bridges combined with Norwegian offshore technology. Instead, an orthotropic deck was chosen, such as the Bergsøysund Bridge had used. The fjord end of the main span is supported by a 30-meter (98 ft) deep foundation, where the two bridges meet. The distance between the cables is 12.00 meters (39.37 ft) on the main span, and 9.33 meters (30.6 ft) on the viaduct. Norway’s proposed floating tunnel. – With a ferry-free connection between Stord and Os, we may see a similar development of the area between Bergen and Stavanger. The main span is built in lightweight LC55 concrete, while the viaduct and pylon is built with conventional C45 concrete. hdwallpapers.in [20], The bridge was officially opened by King Harald V on 22 September 1994. By 1968, the debt would be paid off, but the Norwegian Public Roads Administration launched a plan whereby the tolls would continue to be collected and used to finance a bridge across Salhusfjorden.

The Bjørnafjord Bridge, located south of Bergen, takes its cue from the bridge over the Sognefjord, Norway's largest fjord. The submerged floating tube bridge is certainly an engineering marvel, but the idea isn’t new. Building the world’s longest floating bridge on the E39. [15][16] An H pylon was chosen instead of an A pylon both because it was more functional, and would be more aesthetic in conjunction with the other bridges in the area, particularly three suspension bridges. Consultants sought for Bjornafjord floating bridge concept design. 4). However, the fares would be kept the same and the extra revenue used to finance a bridge from Flatøy to Lindås. The cables have a weight of between 1.5 and 14.5 tonnes (1.5 and 14.3 long tons; 1.7 and 16.0 short tons) each, and they have a capacity of between 1,960 and 7,910 kilonewtons (440,000 and 1,780,000 lbf). The technique had previously been used down to 140 meters (460 ft), but Salhusfjorden is 500 meters (1,600 ft) deep, making the method prohibitively expensive. [8] Both Oslo District Court and Eidsivating Court of Appeal concluded that the tolls were legal, and the issue was rejected by the Supreme Court. This work will be done in parallel with another independent project group. They are longitudinally stiffened by trapezoidal stiffeners supported by cross frames at most every 4.5 meters (15 ft). [2], The use of high-strength steel caused problems as it was necessary to heat the steel to 150 °C (302 °F) before and after welding, and Kværner had problems finding an adequate process during late 1992. [24] In 2009, the bridge had an average daily traffic (ADT) of 14,698 vehicles, up from 7975 in 2000. This is one of the most important factors behind the Norwegian Storting’s decision to prioritize building an improved and ferry-free coastal highway route. We will build safe and sustainable roads for the future, and therefore we are doing elaborate research to ensure that we choose the right and safe solutions. – We face many challenges and therefore need to develop new technology. The submerged roadway would help speed travel along the nation's rugged west coast. 1994; Hasselø 2001). The bridge was financed with NOK 41 million in state grants, NOK 139 million from tolls paid in advance, and NOK 730 million in debt which would be repaid by the tolls. [7] Norwegian expatriate Leif J. Sverdrup, co-founder of Sverdrup & Parcel of the United States, inspected the fjord in 1965[9] and was later hired to plan the bridge in cooperation with Oslo-based civil engineering consultants Prosjektering. However, they were both rejected in favor of a concrete or steel box section borne on concrete pontoons. – We have the necessary knowledge to realize the goal of expanding and strengthening the settlement and labour markets along the West Coast, they conclude. [23] In 2008, there were 19,700 travelers on the bridge each day, 14 percent of which used public transport. World's first 'floating tunnel' proposed in Norway The submerged roadway would help speed travel along the nation's rugged west coast. The components were built in Moss and Fredrikstad and then shipped to Lonevågen, a branch of Osterfjorden which was suitable to connect the parts. World's first 'floating tunnel' proposed in Norway. Seven…. The ferry ride, which takes about 40 minutes, will only take 11 minutes by car when the ferry is replaced by a floating bridge.eval(ez_write_tag([[580,400],'norwaytoday_info-medrectangle-4','ezslot_1',111,'0','0'])); – The whole region will gain from connecting these two cities according to Signe Eikenes and Kjell Håvard Belsvik from The Norwegian Public Roads Administration (NPRA).

It relies on a pontoon-based design with no mooring to the seabed; and it is the second longest in the world of its kind. An illustration shows what a potential underwater floating tunnel, with tubes for traffic going both ways, would look like in Norway. It is sometimes referred to as the Salhus Bridge. The bridge will have spans of up to 800 meters between each float. Lacey V. Murrow Memorial Bridge, Seattle, U.S.A, 2,020 meters, 1940.The bridge carries the eastbound lanes of Interstate 90 across Lake Washington from Seattle to Mercer Island, Wash. It supports a 172-meter (564 ft) main span, with the other end being fixed in a foundation 30-meter (98 ft) below mean sea level, which is anchored in the ridge Klauvaskallen. Following the removal of the tolls, the ADT increased from 9912 in 2005 to 12,249 in 2006. At the same time, it was decided to establish a refinery at Mongstad in Lindås. For extra stability, the bridge-tunnel may also be bolted to the bedrock below. Engineers are currently eyeing one of Norway’s most famous fjords, Sognefjord, as their test case. Norway is building the world's first submerged floating tunnel to cross the fjords. The work will be carried out on behalf of the Norwegian Road Administration region west and involves further developing and documenting four defined use options. Each pontoon consists of nine watertight cells which are partially filled with ballast for trim. – When it comes to the question of construction startup and the question of toll, the Norwegian Public Roads Administration cannot advance the Storting’s future decisions, says Eikenes. It is 1,614 meters (5,295 ft) long, of which the pontoon section is 1,246 meters (4,088 ft) long. 18 Jun 18 Consultants sought for Bjornafjord floating bridge concept design [27] Among the projects is a new four-lane Nyborg Tunnel which will shorten the distance of E39 from the bridge with the motorway at Nyborg in Bergen. It is 1,614 meters (5,295 ft) long, of which the pontoon section is 1,246 meters (4,088 ft) long. By connecting Bergen and Stavanger we will create a powerful region. This allows for a clearance of 32 meters (105 ft). A floating suspension bridge is proposed to cross Norway's Bjornafjord. In 2014, it had an average daily traffic of 16,580 vehicles. Norway to Build World’s Longest Floating Bridge PHOTO: STATE ROADS ADMINISTRATION | The bridge can be built with large floating structures anchored to the seabed. [2], The bridge is monitored by 132 sensors, including sensors on hatches to the pontoons, on doors to the steel box girder, for corrosion, strain gauges on the girder and on flexible elements, and weather information. A bridge over Bjørnafjorden is nevertheless useful for society, emphasizes Belsvik. Norway tenders geotech survey for Bjørnafjord bridge The tender has been published for the geotechnical investigations needed for a planned record-breaking floating bridge across a wide and deep Norwegian fjord. It opened in 2016. Over the decades, the need to replace existing ferry connections with fixed linkes has beed rapidly increasing. External brackets built into the bulkheads transfer the support forces to the pontoons. The clearance under the girder is 5.5 meters (18 ft). The government's solution is to build a bridge that would float on pontoons that would be connected to the fjord's silted seabed with suction anchors. The choice of a box girder bridge and the orthotropic deck were chosen because it gave the lower material use. Plans for a bridge had existed since the 1960s, and after the decision to construct the bridge was passed by the Parliament of Norway in 1989, construction started in 1991. The planned floating bridge will be 5 km long, making this bridge the world’s longest. Building the world’s longest floating bridge on the E39 Aas-Jakobsen, COWI and Multiconsult with Johs.
