The paper presents the fatigue assessment and subsequent design of reinforcement of the Vilvoorde viaduct in Belgium. The project aims to extend the service life of the viaduct, built in 1978, until 2078 with additional lanes of heavy traffic. The calculation strategy developed specifically for this project, combining Eurocode S-N curves, fracture mechanics and inspections, as well as the implemented reinforcements, are presented.
