Helgeland Bridge Wikipedia
The Helgeland Bridge (Norwegian: Helgelandsbrua) is a cable-stayed bridge that crosses the Leirfjorden between the mainland and the island Alsta in Nordland county, Norway. The town of Sandnessjøen is located just southwest of the bridge on the island.
The Helgeland Bridge was designed by Holger S. Svensson. Construction began in 1989 and it was finished in 1991. The bridge officially opened in July 1991. Construction cost was 200 million NOK. The bridge was a toll bridge until 23 June 2005.
The 1,065-metre (3,494 ft) long bridge is made up of 12 spans—the longest of which is 425 metres (1,394 ft) long. The maximum clearance to the sea below the bridge is 45 metres (148 ft). The foundations extend to a depth of 31 metres (102 ft). The bridge is built out of pre-stressed and reinforced concrete and steel cables.
