Sandvika is the administrative center in Bærum municipality and
is located in both the city of Oslo and the greater Oslo region.
Administratively, Sandvika was located in Akershus county, diocesan
county, county and county since the Middle Ages, and in 2020 became
part of Viken county; Sandvika is also located in the diocese of
Oslo. The name Sandvika is associated with the bay in the fjord and
the land that river deposits have formed around the outlet.
Bærum municipal council approved the city status for Sandvika on 4 June 2003. Sandvika is physically a western sub-area in the contiguous urban area of Oslo and has no natural boundaries to other parts of the city of Oslo, so the urban definition of Sandvika is of a purely administrative nature. Sandvika is located southwest of Bærum, in the innermost part of the Vestfjord and approximately 15 kilometers southwest of central Oslo. Bærum's administration, together with most other public services, is located in Sandvika. Sandvika has undergone major infrastructural changes since the end of the 1980s and has grown radically. Sandvika is the municipality's largest administration and trade center.
According to Statistics Norway's statistics for cities and towns, Sandvika, like the rest of the densely populated part of Bærum municipality, is part of the town of Oslo. The city of Sandvika is (as of February 2020) not geographically delimited, and it is therefore difficult to determine the city's exact population and area. Statistics Norway states 115,134 inhabitants from Bærum who belonged to this settlement as of 1 January 2020. There were 127,731 inhabitants in the municipality per. January 1, 2017
The first settlement in Sandvika is connected to past farms such as Løkke, Hamang, Kjørbo and Bjørnegård, which belonged to Nesøygodset. Kjørbo was used as a noble estate instead of Nesøya in the 17th century, while Evje was a church estate until 1840.
Sandviksgrunnene were rich fishing grounds that were originally part of Oxehoved (Blommenholm). Fishing in the fjord provided an important contribution to the farms in Sandvika.
The main traffic route E18 goes through Sandvika, while E16 starts at Sandvika. Sandvika station is one of the largest in the district. Here, both Flytoget and selected Inter-city trains stop on the Asker line and local trains on the Drammen line. At the train station there is also a bus station and taxi rank.
In addition to cars and trains, public transport is based on buses. Traffic to Oslo from the municipality is otherwise located (metro, buses) at Bekkestua (metro, tram, buses) and Østerås
Sandvika has a large cinema (Kino 1) with eight halls, and right next to this is Bærum Kulturhus with 500 seats. This is mainly used for dance performances and concerts. Sandvika Theater, formerly Sandvika Cinema, is today used mainly for children's theater, Bærum Children's Theater and Sandvika Children and Youth Theater. Close to the theater is also the club stage Musikkflekken. Baracoa Bar and Stage have weekly concerts. Since the beginning of 2000, Sandvika has played an important role in Norwegian modern music.
In the fjord outside Sandvika is Kalvøya, an island that is connected to the mainland via an approx. 100 m long suspension bridge. In the summer, people go on beach trips here, and festivals, football matches and private groups use Kalvøya.
