"This elegant span, with its handsome profile stretching 67 meters [220'] above the Ringdalsfjord, is Northern Europe's highest bridge. The Svinesund Bridge was opened with great ceremony on 15 June 1946, by the Norwegian king and the Swedish crown prince. The traffic has increased over the years, and at the end of last century it was decided to build a new highway and bridge between Norway and Sweden. June 10th 2005 the new bridge opened between those two countries."

"The Svinesund Bridge is a through arch bridge crossing Iddefjord at Svinesund and joining Sweden and Norway. It was completed in 2006. The bridge is 704 m long and has a clearance high of 55 m [180'] above the water."

"Arching 302 ft. (92 m) above the Iddefjord between Halden, Norway and Strömstad, Sweden, the Svinesund bridge opened to traffic on June 13, 2005....The arch is hollow, and employs heating coils to prevent the buildup of snow and ice. It also contains interior maintenance pathways to simplify access for the bridge’s upkeep."

"The bridge features two separate lanes for automobiles, as well as a dedicated lane for bicycles and pedestrians."

"The bridge is 420 meters long and the main span is 155 meters. The bridge was protected by Directorate for Cultural Heritage who believed that the bridge is a symbol for the connection between Norway and Sweden" To use the ferry before this bridge was built meant that you had to go down into the valley and then climb back out of it.

"The construction of the arch used a climbing formwork and the cable-stayed cantilever construction method known as the ‘Freivorbau’ technique. Using this method the arch is temporarily supported during the construction by cables that are anchored to auxiliary towers. The two towers are securely back-anchored in the rock using high tensile steel cables and are then dismantled following the completion of the arch."

The deck has two steel box-girders tied together with cross girders.
