Harpe Bru Bridge, Norway

Projekt data

Sted: Sør-Fron (Oppland), Norge

  • Total length of extradosed bridge: 320 m
  • Largest span between the pylons: 100 m


  • Complex cross-sections with 130 cm high cross-ribs on both sides of the upper slab, at each segment
  • Pouring of each segment in two steps: first bottom slab, walls and all ribs, second upper slab
  • Suspending cables at most of the segments; collision with the carriages had to be avoided
  • Assembly had to be orgnized in a special way because of the flood forecast for the river
  • Special planking on the surface of the formwork

Mariusz Urbanski
Construction Manager

The chosen solution of using VBC Balanced Cantilevered Carriages proved itself to be correct. Thanks to the high flexibility of the system, we could optimize our project so that the workload necessary to pour each segment was as short as possible. It also had a measurable influence on the assumed schedule.
