One of the main objectives of building the tunnel was to replace one of Iceland's most dangerous roads, which connected two of the largest towns in the area, Ísafjörður and Bolungarvík, and thereby improve road safety. The old road lies along the seashore under the steep and unstable mountain hills of Óshlíd, and was subject to frequent avalanches and rockfalls. Other objectives include improved road connections and reduced travel times, such that the distance between Ísafjordur and Bolungarvík would be similar to that between districts in a city.[2]
