[4] The official Visit Norway website has claimed Vikings would drag their boats over the peninsula to avoid crossing the dangerous patch of sea.

[6] Knut Samset, a project management professor with at the Norwegian University of Science and Technology, criticised the decision to go ahead, claiming modern vessels could navigate the seas safely and that "cost-benefit analysis is negative".

[11] Terje Andreassen, temporary project manager, stated that construction was expected to start in 2023[12] with an estimated completion in 2025 or 2026.

[10] The tunnel's entrances have been designed by Norwegian firm Snøhetta with rock walls left rough to blend into its surrounding landscape.

[6] Snøhetta's designs include walkways and the construction of a new road bridge to enhance views of ships passing in and out of the tunnel.

Instead, the tunnel will cater primarily to smaller vessels, including coastal ferries and other small passenger ships, offering an unforgettable journey through this innovative passage.

[19] After years of little communication following the announcement of the plans, the Norwegian Coastal Administration has now published the tender for the tunnel’s construction, with a pre-qualification deadline set for the end of January 2025.
