The steep and inaccessible terrain in the area gave special challenges when it comes to conducting and construction design. This led to the creation of a new and inventive construction method for a large suspension bridge.

The feasibility study was optimized by reduced construction cost, safer conducting, improved visual expression and less terrain intervention by the coastline and the mountain side.

Of special tasks performed it can be mentioned description and implementation of wind tunnel surveys, and subsequent implementation into dynamic wind analyzes.

Tender documents were completed in December 2018. Construction of the bridge is planned to start in the first half of the 2020’s.
