It is a single tube with two lanes of a total width of seven metres and a 1.5 m shoulder at each side. The project also includes new roads outside the tunnel of approx. 2.2 km.The method of excavation is drill and blast using an Atlas Copco Rocket Boomer L3C with three booms (year 2003). The supplier of explosives is Kemis of Iceland. The detonators are from Austin Detonator's facility in the Czech Republic. The explosives have been made by Minex of Poland. Support techniques are traditional fibre-reinforced shotcrete and rock bolts. Rock bolts are from Orsta in Norway. Istak is operating its own concrete batching plant.
