ABSTRACT
The Swedish National Road Administration is responsible for the management of around 11000 bridges included in the national road network. In this context, a ‘bridge’ is a structure with a free opening of at least 3·0 m in the longest span. Of these bridges, some 8500 are made of concrete, 1800 of steel and 700 of stone. About 400 of the concrete bridges are made of prestressed concrete.
