For the past year, two different groups have been commissioned by the Norwegian Public Roads Administration (NPRA) to study four different concepts for crossing the Halsafjord and five different concepts for crossing the Sulafjord. The Norconsult and  Dr.techn. Olav Olsen joint venture has together with their strategic partners completed pre-engineering for 4 different bridge concepts for a fixed crossing for the E39 over Halsafjord and Sulafjord.
