ABSTRACT
During the ‘60’s and ‘70’s of the last century the Dutch highway network has been expanded enormously. Both technical and economic developments since that time have led to an increase in traffic load; the number of vehicles has grown tremendously as well as the axis loads. Most existing steel highway bridges are not capable to carry these loads and thereby are reaching the end of their technical lifetime. The Dutch government has decided to renovate some of these bridges instead of building new ones. This paper describes the way a program has been set up by combining the renovation of 14 bridges in order to develop new and innovative renovation techniques and to share knowledge between all parties involved. Continuity in the organisation, knowledge management and risk management have shown to be key aspects of this program in be-coming reliable and predictable for both the public decision making and the public.
