Rogfast Undersea Tunnel
- Rogfast is a 27 km twin-tube subsea road tunnel between Randaberg (near Stavanger) and Bokn on the E39, reaching 392 m below sea level, with a spur to Kvitsoy[2][3]
- It replaces ferry crossings and cuts Bergen-Stavanger travel by around 40 minutes; it is tolled and operated by the Norwegian Public Roads Administration[2][3]
- Approved by the Storting in May 2017 at NOK 16.8 billion, work began 4 January 2018; it was halted in October 2019 over cost overruns and the cost was set at NOK 24.8 billion in November 2020[2]
- Opening is slated for 2033 at about NOK 25 billion (roughly $2.4 billion)[2][3]
- Skanska builds the northern section (contract December 2022), Implenia the southern (January 2023) and Implenia/Stangeland the middle (June 2024)[2][3]
- Ventilation is longitudinal with jet fans plus shaft ventilation; challenges include saltwater leaks and grouting at 300 m below sea level[3]
