NORWEGIAN infrastructure manager Bane Nor has awarded Swiss civil engineering contractor Implenia an NKr 18.8bn ($US 2bn) contract to build the double-track Tangenvika bridge, which at 1020m will be Norway’s longest railway bridge.
The new prestressed concrete box structure will cross Lake Mjøsa and Implenia says special care will be required during construction as the lake is both a source of drinking water and home to a rich variety of fauna.
The contract includes 2km of new alignment on land where provision will be made for wildlife to cross over the railway. Transport of materials during the construction phase will be kept to a minimum through the careful location of storage areas and the use of local rock.
Work on the project is due to start in the second quarter of 2022 and is scheduled for completion in 2027.
