The location of the main airport serving the city of Oslo, Norway, has been the subject of several political debates since 1918. The first controversy was initially related to choice between the islands of Gressholmen and Lindøya in the Oslofjord for a water aerodrome. The debate later changed, arriving at the decision in 1933, to locate a new airport at Fornebu. However, Oslo Airport, Fornebu, being located on a peninsula, proved to not have sufficient space for a runway capable of intercontinental aircraft and a second runway, resulting in plans from the 1960s to replace it. The main contestants were Gardermoen Air Station, Hurum, Hobøl, Ås and a split solution between Fornebu and Gardermoen. In 1992, parliament decided to build an all-new Oslo Airport, Gardermoen; when it opened in 1998, Fornebu was closed. The decision caused the southern parts of Eastern Norway to be moved further from the main airport, and the regional, privately owned Sandefjord Airport, Torp became the base for low-cost airlines. Moss Airport, Rygge opened in 2007, becoming the third simultaneous airport to serve Oslo, and closed in 2016.
The Hurum Line was a proposed railway line which would have connected Røyken and Hurum in Asker municipality, Norway. Launched during the Oslo Airport location controversy during the second half of the 1980s, its main purpose was to act as an airport rail link to serve the proposed national airport on Hurumlandet. The main proposal for the line called for a 14-kilometer (8.7 mi) section of double track which would branch from the Spikkestad Line at Hallenskog. Construction of the Hurum Line would have seen 7 kilometers (4.3 mi) of the Spikkestad Line upgraded to double track as well as upgrades to the Drammen Line. The distance from Hurum to Oslo is 45 kilometers (28 mi), with travel time estimated at 35 minutes.
