Triangle Link

Historie

The Triangle Link is a fixed link with three branches that connects the islands of Stord and Bømlo to each other and to the mainland at Sveio, Norway. It consists of the underwater Bømlafjord Tunnel from Sveio to the island of Føyno, the Stord Bridge from there to Stord, and a road including the Bømla Bridge and the Spissøy Bridge to Bømlo. The section from Sveio to Stord is part of European Route E39, while the branch to Bømlo is part of County Road 542.
The Bømlo Tunnel is 7,860 meters long and reaches 260 meters below mean sea level. It is the longest subsea tunnel in Norway and was the deepest in the world when it opened. The Stord Bridge and Bømla Bridge are both suspension bridges, with lengths of 1,077 and 998 metres and main spans of 677 and 577 meters. The Spissøy Bridge is a 283-meter beam bridge. The link is 21.5-kilometer long toll road with a toll plaza on Føyno. The section from Stord to Bømlo has a pedestrian and bicycle path.
Plans for a link between Bømlo and Stord were first launched as a pontoon bridge in the 1960s. In the late 1980s, the plans evolved into a triangular project. There was controversy surrounding the project, in particular from environmentalists.
