Abstract (EN): In this work a 5 span prestressed concrete box girder bridge exhibiting cracking related pathologies is presented. Built in the late 70’s, this was the first bridge to be built by the balanced cantilever method in Portugal. A detailed non destructive inspection also revealed several prestressing ducts exhibiting corrosion signs, sustaining the assumption of corroded prestressing steel in the box-girder bottom slab. The bridge was monitored during a load test and during the 4 subsequent days under normal traffic and thermal actions. The obtained results are presented as well as the conclusions of a preliminary safety evaluation.
