Espern Bru Bridge

Creating an essential link between a new district and its town centre

The Espern Bru bridge will play a central role in the new urban district that the Norwegian municipality of Hamar wants to create on a former industrial port area. Spanning a railway line, it will provide a privileged link between the new district and the town centre, while facilitating access to the various construction sites during the works. Artelia is responsible for the design of this 114 m-long structure, which will be equipped with cycle and pedestrian lanes.


Located to the north of Olso, the municipality of Hamar has launched the conversion of a former disused industrial estate into a lively new urban district offering flats and commercial buildings. As the area is cut off from the rest of the city by a railway line, it decided to build the Esperen Bridge, which will play a key role both during the works, to provide access to the various construction sites, and subsequently to link the new district to Hamar town centre.

An international team has been formed within Artelia to design this structure. The Group’s subsidiary, Dr techn Olav Olsen, carried out the structural calculations on which the bridge is based, while Artelia Denmark is responsible for its 3D design, with the help of Artelia Philippines. The 114 m-long, two-way structure will accommodate two lanes for motor traffic, one for cycles and one for pedestrians. Its twenty sections, built in Poland, will be assembled and welded on site in three parts, which will then be hoisted above the railway tracks.
