Abstract:Due to of Norways distinctive topography,bridges have been necessary for mobility and accessibility for decades.This presentation gives a brief historical overview of the development of long-span bridges in Norway.From the 1950s,when the suspension bridges were designed with stiffening girder of trusses,until today,when we build even longer spans of modern aerodynamic steel box girder bridges.Also our two floating bridges built in the 1990s are described.In addition,this presentation provides an overview of our new Coastal Highway Route E39 Project.It is planned to replace seven different ferry connections with pioneering designs and constructions.Suspension bridges,cable stayed-bridges,floating bridges,submerged floating tube bridges or a combination of these bridge types.Here is presented the results of the feasibility study that shows alternative methods of crossing "extreme fjords",where the width varies from 2 to 7.7 km and depths up to 1,300 m.The project also includes evaluating whether to use the experiences of Norwegian oil and offshore technology to cross these fjords.The conclusion of this feasibility study shows that this is technically feasible,and the ambition of the Norwegian Government as well as the Parliament,is that E39 corridor will be completed within 20 years from 2014.
