Bolungarvík tunnel project progressing apace
During the summer Ósafl has been excavating rock from the mouth of the planned Bolungarvík tunnel. The project is moving forward very well, with a crew of some 30 workers presently on the job and more scheduled to join them in the weeks to come. All loose material has been removed from the tunnel face on both the Bolungarvík side and the Hnífsdalur side. Blasting will commence at the end of the month.
Work will be done from both ends at once; that is, from Fremri-Ós in Sydridalur valley in Bolungarvík, and at Skarfasker in Hnífsdalur. The creation of the tunnel generates an enormous amount of excess material. The approximately 317,000 m3 of blasted rock coming from the tunnel itself will be used in road construction. In addition, a large amount will be removed from the tunnel mouth on both ends. About 150,000 m3 of material already cleared from the mountain above Skarfasker at Hnífsdalur has been used to fill a new road lying towards the coast near Hnífsdalur cove, right by the town of Hnífsdalur. BM Vallá has set up a concrete works in Bolungarvík for the job and will manufacture concrete for the construction of the portal structures at both mouths and for bridges to be built in connection with the project.
The tunnel will be 8 metres wide and 5.1 km long, and the combined length of the portal structures will be 310 metres. In addition, a total of 3.7 km of roads will be laid at both ends of the tunnel, and two bridges will be built: an 8m bridge over Hnífsdalsá river and a 32m bridge over Ósá river in Bolungarvík. Completion of the project is scheduled for 15 July 2010.
