Thw world's longest cable stayed bridge, the Skarnsundet Bridge, will be completed on schedule close to the Arctic Circle in Norway. The concrete bridge has a slender 42.6 ft wide, 7 ft deep triangular sectioned box girder deck. It is hung between two A-shaped towers rising 499 ft above water level. Steep fjord banks limit anchor span lengths to 623 ft requiring concrete ballasting to balance cable loadings. A total of 208 locked coil cables with galvanized external wires support the bridge. Because of the structure's slenderness, extensive wind tunnel testing was commissioned that led to a 10% increase of the design wind speed and more unfavorable wind spectra. These and other design modifications led to a $2.2 million price hike. Also, swift currents during tidal changes, gave only a couple of 2-hour periods a day in which to excavate pylon foundations. These and other problems threw the contractor's finances in turmoil leading to its current takeover.
