The Helgeland Bridge (Norwegian: Helgelandsbrua) is a cable-stayed bridge that crosses the Leirfjorden between the mainland (in Leirfjord Municipality) and the island of Alsta (in Alstahaug Municipality) in Nordland county, Norway. The town of Sandnessjøen is located just southwest of the bridge on the island.^[1]
