built with conventional C45 concrete. Inside the pylons is a hollow area. The bridge has 48 cables, 12 on each side of the pylon on each side of the roadway. The distance between the cables is on the main span, and on the viaduct. Combined, the cables are long; each cable consists of 67 to 230 twined cables, each with a diameter. The cables have a weight of between each, and they have a capacity of between . They can be tightened at the connection with the roadwall. The floating section consists of a steel box girder placed on top of ten floating pontoons. The pontoon section is anchored only at both ends, on the underwater foundation at Kauvaskallen and on Flatøy. It is fastened using flexible plate connections fastened by bolts and cables under tension. These are flexible around the horizontal axis at right angles towards the axis of the bridge, allowing for deformation caused by the tide. The fastening on Flatøy consists of a massive concrete block long and tall which was poured into a blast-out foundation pit in bedrock. Vertical pretension rock anchors have also been installed, with 12 at Klauvaskallen and 14 at Flatøy, giving of support, although they were only built to increase the safety factor. There are ten lightweight concrete pontoons, with spans between them. The pontoons are between in height. The draught varies between . Each pontoon consists of nine watertight cells which are partially filled with ballast for trim. The cells are dimensioned so two adjacent cells can fill with water without endangering the bridge. The roadway lies on top of an orthotropic deck on a steel box girder, which is wide, tall and long. The steel box girder weighs , of which is high-strength low-alloy steel. The girder has an octagonal shape and is made with thick steel plates. They are longitudinally stiffened by trapezoidal stiffeners supported by cross frames at most every . Two full bulkheads have been used for every pontoon pilaster, made from welded steel plates thick. External brackets built into the bulkheads transfer the support forces to the pontoons. The girder was built in sections of 21, 36, and 42 meters (69, 118, and 138 ft), which were subsequently welded together into 11 modules with a skew angle of 1.2 to 1.3 degrees. The girder has a constant cross-section throughout the length, except at the anchoring points
