Hålogaland Bridge

Project description

The Hålogaland Bridge is a 1,533 m-long suspension bridge which crosses the Rombaksfjorden in the municipality of Narvik in Nordland county, Norway.

It will be part of the E6 Halogaland Highway project. The project includes the construction of two short tunnels, the Ornestunnelen and Storlikolltunnelen, as well as the construction of two new roads on both sides of the Hålogaland Bridge. It will shorten the driving distance between Narvik to Bjerkvik by 18 km and between Narvik to Bjørnfjell by 5 km.

The 1.5 km Halogaland Bridge will be the second longest suspension bridge in Norway.

The span of the bridge will be built as a closed steel box girder resting on five pillars with height ranging from 12 m to 30 m, with a clear height of 40 m and a clear width of 200 m.

mageba scope

In terms of joints mageba supplied two TENSA-MODULAR expansion joints of type LR17 with a total length of 27.8 m. The joints featuring the Quck-Ex system which in case of a joint replacement brings huge advantages.

The main pillars are supported by two RESTON-FORCE horizontal force bearings.The bearings are designed for a maximum horizontal load of 1,800 kN (ULS) and longitudinal movements of +/– 450 mm and with a weight of 4 tons each. A critical issue the bearings is the accommodation of vertical rotations. In order to provide the best possible solution, an elastomeric pad was installed within the bearing.

Two RESTON-STU Shock Transmission Units designed with a maximum axial load of 10’400 kN (ULS), an axial stroke of +/– 450 mm and a weight of 6 tons. Due to limited space on site, the units were designed with two separated chambers with different volume of oil.
