The country's transport ministry on Sunday published its preliminary feasibility studies into the bridge and confirmed that it had decided to push ahead with the project,
Transport Minister Engelbrecht said the bridge made sense “from a climate perspective”, in a press release issued with the announcement.
“Imagine how a Kattegat connection could reduce the number of domestic flights due to the significantly shorter travel times between Jutland and Zealand,” he said in the statement.
The previous centre-right government in 2018 announced that it wold spend 60m Danish kroner on a study into the bridge.
Earlier studies estimated that the bridge could cost between 58bn and 136bn Danish Kroner, depending on whether it carried trains or not. The feasibility study will report its final conclusions in 2021.
The link will probably consist of two separate bridges, one 18.3km link between Hou, south of Aarhus, and the island of Samsø, and another linking Samsö to Røsnæs on Zealand.
But the investigation is also looking at a longer single bridge linking the Sjællands Odde peninsular on Zealand to Djursland, north of Aarhus.
The proposal has generated opposition from conservationists who argue that building a motorway linking to the bridge on the Røsnæs peninsular would destroy an area of great natural beauty.
