Current Record
292m below sea level
Current record value
Ryfylke Tunnel forms the main part of the Ryfast project, running between Solbakk in Ryfylke and Hundvåg near Stavanger and replacing a ferry-dependent road connection.
The Norwegian road authority lists Ryfylke Tunnel at approximately 14.3 km. The other Ryfast tunnels opened in April 2020, making the project a multi-tunnel network; the record applies only to Ryfylke Tunnel's deepest road level.
The record conclusion has sufficient verification support.
Basis: direct confirmation by an authority
The Norwegian Public Roads Administration identifies the opened Ryfylke Tunnel as the world's deepest subsea road tunnel, reaching 292 m below sea level and opening on 30 December 2019. It must not be conflated with the whole Ryfast network.
