Already dubbed "the most beautiful bridge in the world" by local residents and engineering aficionados alike, Hålogaland Bridge is unique and immediately recognizable.

  • With a main span of 1,145 meters, it is the longest spanning bridge ever built north of the Arctic Circle.

    Hålogaland Bridge incarnates a principle most architects and engineers seem to agree on; while bridges need to be functional, safe and durable, they should also be elegant and beautiful. When done right, bridges become a symbol of their location and part of the local story and legacy.

    The distinctive appearance of Hålogaland Bridge has been achieved by A-towers, a spatial cable system and the main cable anchorage in rock, all of which minimize the visual and physical impact on the surroundings and unite the structure with the surrounding mountains.

    A distinctive suspension bridge

    Hålogaland Bridge is a distinctive suspension bridge with its simple and logical design and features like its A-shaped pylons and illuminated pylon tops. In general, suspension bridges are considered to be among the most elegant types of bridges, but it can be difficult to give them an individual appearance because of their simple, dominant expression in the curve of the main cables. This is not the case for Hålogaland Bridge; the location and special functional requirements such as a narrow bridge deck and long bridge span mean it was possible to achieve a distinctive look for the suspension bridge.

    The low volume of traffic called for a narrow box girder carrying two lanes of road traffic beside a bicycle/pedestrian lane. Combined with a main span length of more than 1,145 meters, the record-breaking slender bridge pushes the boundaries of aerodynamic design.

    The design and construction can contend with powerful Arctic winds and thermal expansion-contraction in a region where seasonal temperature swings reach 40 degrees centigrade. The bridge marks a significant advancement due to these extreme natural stresses and conditions.

    Faster and safer

    Hålogaland Bridge allows quicker, easier and more reliable travel across the deep waters of Rombaksfjorden in the city of Narvik as a part of the E6 Narvik – Bjerkvik, Norway’s primary north-south highway. The bridge shortens the E6 by as much as 18 kilometers and draws traffic away from a stretch of E6 to reduce the risk of accidents, avalanches and landslides.

  • En usædvanlig hængebro

    Hålogalan- broen skiller sig ud som en hængebro med sit simple og logiske design. Generelt anses hængebroer for at være de mest elegante brotype, men de kan samtidig være vanskelige at give et unikt udseende på grund af deres enkle, dominerende udtryk, der kommer af hovedkablets kurve. Det er dog ikke tilfældet med Hålogaland-broen; placering og geometri har givet en mulighed for at designe en karakteristisk og let genkendelig bro; forholdet mellem banernes bredde og hovedspændets længde er sjældent, og har åbnet for udformningen af broens A-formede tårne.

  • A-formen gør, at kablerne kan hænge i et vinklet plan. Tårnets ben, der står på en elliptisk base, har et simpel, let vinklet, rektangulært tværsnit. Den slanke bro har skubbet til grænserne for det aerodynamiske design.

    Design og konstruktion kan samtidig modstå de kraftige arktiske vinde og temperaturudsving. Den er også en mere sikker rejse over fjorden som en del af E6 Narvik-Bjerkvik, Norges primære nord-sydlige motorvej. Den nye forbindelse trækker trafik væk fra en strækning af E6, som tidligere har været plaget af ulykker på grund af laviner og jordskred.
