The 10.8 km long road tunnel is expected to open in December 2023, and Faroese authorities estimate that traffic through the tunnel can be around 300-400 cars per day.
There are currently two undersea tunnels in the Faroes (Vágatunnilin 2002 & Norðoyatunnilin 2006). The third one (Skálafjarðartunnilin) will open in 2020.
