One point two metres. That is the depth of the concrete box girder that carries traffic 425 metres across the Leirfjorden in Nordland — a deck barely deeper than a doorway is wide, holding up a span longer than most suspension bridges of its era. Seen from a boat underneath, the Helgeland Bridge hardly reads as a structure at all. It reads as a drawn line: a pale stroke pulled taut between two towers, with the wall of the Seven Sisters mountains standing behind it. That thinness is not a flourish or a happy accident. It is the whole argument of the design, and it made the bridge one of the most-studied concrete crossings in Europe when it opened in July 1991.

Divide the 425-metre main span by the 1.2-metre depth of the girder that spans it and you get roughly 354. Engineers call that number slenderness, and at 1:354 the Helgeland Bridge pushed the figure further than concrete cable-stayed construction had gone before. The deck is only...

The bridge was designed by the German engineer Holger S. Svensson, and building it meant working outward into thin air. Crews cast the deck in segments by free cantilevering, extending it from each tower in both directions at once, adding stay cables as they went, so that the hal...

The bridge lands on Alsta, an island dominated by a chain of summits that local legend turned into seven sisters. Botnkrona is the tallest at 1,072 metres, with Skjerdingen, Grytfoten, Kvasstinden, Breitinden and the pair known as Tvillingan — the twins — completing the ridge. Hi...

The Helgeland Bridge belongs to County Road 17, the Kystriksveien, a 630-kilometre coastal route running from Bodø south to Steinkjer through some of the most broken geography in Norway. Even now the drive includes six ferry crossings, each with its own timetable to plan around. ...
