The Osterøy Bridge (Norwegian : Osterøybrua) is a suspension bridge in Hordaland county, Norway. The bridge connects the Kvisti farm area on the island of Osterøy with the Herland farm area on the mainland east of the city of Bergen. The bridge is the third largest suspension bridge in Norway. It is part of Norwegian County Road 566 (Fylkesvei 566). [1]

Norwegian language North Germanic language spoken in Norway

Norwegian is a North Germanic language spoken mainly in Norway, where it is the official language. Along with Swedish and Danish, Norwegian forms a dialect continuum of more or less mutually intelligible local and regional varieties, and some Norwegian and Swedish dialects, in particular, are very close. These Scandinavian languages, together with Faroese and Icelandic as well as some extinct languages, constitute the North Germanic languages. Faroese and Icelandic are hardly mutually intelligible with Norwegian in their spoken form because continental Scandinavian has diverged from them. While the two Germanic languages with the greatest numbers of speakers, English and German, have close similarities with Norwegian, neither is mutually intelligible with it. Norwegian is a descendant of Old Norse, the common language of the Germanic peoples living in Scandinavia during the Viking Era.

Suspension bridge type of bridge

A suspension bridge is a type of bridge in which the deck is hung below suspension cables on vertical suspenders. The first modern examples of this type of bridge were built in the early 1800s. Simple suspension bridges, which lack vertical suspenders, have a long history in many mountainous parts of the world.

Hordaland County (fylke) of Norway

Hordaland is a county in Norway, bordering Sogn og Fjordane, Buskerud, Telemark, and Rogaland counties. Hordaland is the third largest county after Akershus and Oslo by population. The county government is the Hordaland County Municipality which is located in Bergen. Before 1972, the city of Bergen was its own separate county apart from Hordaland.

The Osterøy Bridge is a 1,065-metre (3,494 ft) long suspension bridge that has a main span of 595 metres (1,952 ft). There are 8 spans, and none of the piers are in the water, just on land. There is 53 metres (174 ft) of clearance below the bridge. The two suspension towers are each 121.5 metres (399 ft) high. The bridge was completed on 3 October 1997 and cost about 308 million kr. The bridge was designed by the structural engineering firm Aas-Jakobsen. [2] [3] [4]

The company is based in Oslo, Norway, and primarily works with bridges, roads, railways, offshore oil and buildings. The company has 250 employees. The company was established by Andreas Aas-Jakobsen in 1937. For the first decade, the company specialized in shell structures, but from the 1950s, the company shifted to bridge design. The company later started designing offshore installations and became a verifier for such structures, and later also became a consultant for railway projects and major road projects, such as the Bjørvika Tunnel through Oslo.

It was put into service 28 years after the first plans for a connection between Osterøy and Bergen were prepared. It was opened for traffic by Sissel Rønbeck, the Norwegian Minister of Transport and Communications. The bridge was built to withstand quite strong winds. Experts have indicated that the bridge should be capable of surviving an extreme storm. The bridge is tuned so that its greatest oscillation occurs when the wind is about 10 metres per second (22 mph) such as a light breeze.

Oscillation repetitive variation of some measure about a central value

Oscillation is the repetitive variation, typically in time, of some measure about a central value or between two or more different states. The term vibration is precisely used to describe mechanical oscillation. Familiar examples of oscillation include a swinging pendulum and alternating current.

The Storfjord Bridge is a proposed suspension bridge that would span Storfjorden in Sunnmøre, Norway. If built, it would be 3,600 metres (11,800 ft) long and have a main span of 2,300 metres (7,500 ft). This would make it the longest spanned bridge in the world, easily surpassing the Akashi-Kaikyō Bridge, which has a main span of 1,991 metres (6,532 ft). The plans have been developed by Aas-Jakobsen for a Storfjordsambandet, a company which aims to toll finance the bridge. According to Rolf M. Larssen of Aas-Jakobsen, there is a larger challenge securing sufficient funding than technically building the bridge. It is estimated to cost 4.3 billion Norwegian krone.

A symphony bridge or bridge symphony is a bridge which combines the structural support systems of a suspension bridge, a cable-stayed bridge and a cantilever bridge. No such bridges have been built, nor are there any specific plans, although the method has been considered for several bridges in Norway. It was developed collaboratively by the Norwegian Public Roads Administration and the civil engineering consulting company Aas-Jakobsen as a means of building bridges with spans between 1,000 and 3,000 meters.
