The Sykkylven Bridge, located on the West Coast of Norway, was opened in October 2000. The long needed private financed bridge links two villages at each side of the fjord together, and gives a valuable contribution to expansion of the community which is characterised by several furniture manufacturers. The engineering challenge was mainly to find an economical solution for the 860 meter long crossing over the 30 meter deep fjord. This paper describes a solution where a traditional girder bridge, concrete or steel, is supported on piles free spanning from the water surface to the seabed. The piles consist of up to 68-meter long steel pipes, which are reinforced and poured with concrete. Compared to a traditional solution with prefabricated caissons, these solutions will in many cases be less expensive, and particularly at Sykkylven, it was important for the realization of the project. This paper discusses structural and geotechnical aspects such as, safety, analysis and design, construction and the important interaction between designer and contractor during the construction phase.
