Floating Bridge:
The bridge consists of a continuous bridge deck between land abutments on each side of the fjord, with a total bridge length of 2,630 meters.
On the western side, the deck is supported by a cable-stayed bridge spanning 870 meters, providing sufficient clearance for a navigation channel measuring 370 x 50 meters (W x H).
Outside the navigation channel, the deck is supported by steel columns on floating steel pontoons.
The floating bridge is anchored at both ends and rigidly connected to the abutments, with no expansion joints or bearings.
Suspension Bridge via Aakvikgrunnen:
Main span of 1,641 meters and a suspended side span of 560 meters.
The tower at Halsaneset is located on land, while the tower at Aakvikgrunnen is founded on a gravity-based structure (GBS) at a depth of approximately 90 meters.
Single-Span Suspension Bridge:
The suspension bridge crosses the Halsafjord between Halsaneset (west) and Orneset (east).
It features a main span of 2,065 meters.
On the west side, there is a 231-meter viaduct, and on the east side, a 97-meter viaduct, both proposed as concrete box girder bridges.
The project was presented at IABSE Ghent 2025: Halsafjorden, full paper.pdf
“
Bridge and offshore technology developed over several decades has been combined and refined in these feasibility studies to enable crossings of new fjords in the ferry-free E39 project.
