Assignment text
County Road 53 between Øvre Årdal and Holsbru, on the stretch Årdal – Tyin.
The project is divided into 3 geographical areas. Ljoteli with tunnel and open air zones, landfill areas at Holsbru and a smaller landfill at Holsbruvannet.
A 1,100 m long tunnel will be constructed (T8.5 + sight expansion), as well as cuttings and transition zones. The assignment also includes complete electrical works in the tunnel.
At Holsbru (2,5 – 3,0 km over Ljoteli) approx. 600 m of open air road will be constructed, with cross section 6,5 m + ‘crawler lane’, Sa3.
From Holsbru and toward Holsbruvatnet, a 400 m long ditch will be established along the existing roads.
The assignment will primarily be implemented model based.
