Given the reduced width of the carriageway, it was not possible to use the by-bridge and it was therefore decided to create anchorages in the insole and employ technicians specialized in rope processing by preparing a simple rationalization of the carriageway by establishing the alternating one-way. Surveys conducted on the bridge include both de-structive and non-destructive surveys and could be divided into two macro-groups: Surveys for the survey and verification of geometries and construction details and Surveys for the characterization of materials. The first group is designed to investigate, detect or verify the number of the present longitudinal and transverse irons, the height of the iron cover and the geometric dimensions of the structural elements; the second group is to investigate the resistance characteristics of the materials such as removal of concrete cores and reinforcing bars, SonReb and hardness tests.
