Abstract The knowledge on the effective long‐term behavior of large civil infrastructures, for example, bridges, is becoming highly desired by owners and concessionaires. Based on the case of the Lezíria Bridge in Portugal, one of the most comprehensive case studies available in the literature, a set of good practices to achieve reliable assessments on the long‐term behavior is outlined. Spanning the construction phase, the loading test (at the end of construction) and the operation phase, the behavior of the bridge is well predicted for several physical parameters. Nevertheless, the extrapolation of creep and shrinkage models, the influence of interior and exterior environments, and significant thickness variations along cross‐sections are key issues that deserve special attention. The role of advanced FE modeling supported by monitoring data is showed to be one of the most robust approaches for supporting the management of large civil infrastructures in this era of digitalization (Industry 4.0).
