Skarnsund Bridge - Specifications

Specifications

The bridge is one of the world's longest cable-stayed bridges, with a length of 1,010 metres (3,310 ft). The span is 530 metres (1,740 ft), while the two towers are 152 metres (499 ft) above sea level. The deck is 2.15 metres (7.1 ft) deep, and 13 metres (43 ft) wide, with two lanes for automobiles and one for pedestrians and bicycles. It is the longest concrete cable-stayed span. The sailing height is 45 metres (148 ft). The bridge was, on its completion, the longest cable-stayed bridge in the world by the length of main span, but has since lost the title.

The original construction work also included 1.6 kilometres (1.0 mi) of new road, including a resting place on the Mosvik side. In the construction of the bridge, 19,600 cubic metres (25,600 cu yd) concrete was used and the 208 cables, with a total length of 33 kilometres (21 mi), weighed 1,030 tonnes (1,010 long tons; 1,140 short tons). The cables have diameters varying between 52 and 85 millimetres (2.0 and 3.3 in) and can, if needed, be replaced separately. The bridge's foundations are bedrock below the seabed under each tower. The bridge was built to withstand winds up to 48.5 metre per second (159 ft/s) (century storms) and has been designed to withstand earthquakes.
