The two partners Implenia and Stangeland Maskin have already worked together successfully on previous projects: They have previously built the Eiganes Tunnel together and are currently working as a joint venture on the E39 Lyngdal project.
Sub-project E04 was also awarded in December 2022. This northernmost section of the Boknafjord Tunnel is being built by the Swedish company Skanska. It is a twin tunnel that will involve Skanska building 18.5 km of road in the tunnel and another 2 km above ground. The contract is worth around 460 million euros. Construction is scheduled to start in the first quarter of 2023 and be completed by the end of 2029. The remaining middle tunnel lot E02 has not yet been awarded.
