First of its kind in Scandinavia
In this joint venture, PNC was responsible for the construction of Harpe bridge, which is the first of its kind in Scandinavia. Considering the large trout spawning grounds the bridge should not have more than two pillars in the river. The choice fell on a hybrid bridge, or a so-called extradosed bridge.
This is a combination of sloping cable bridge and prestressed beam bridge, but with a lower tower height and a softer angle on the towers. The bridge was built as free cantilever from each tower axis, while the side span was built on scaffolding. The bridge with four lanes is part of the E6 and 324m long.
