In 2007, the department of Vaucluse carried out an inventory and assessment program in respect of its structures in order to take an inventory report on its stock of structures and to set up a database to assist in the management of these structures. A program of repairs was launched as a result in respect of a large number of structures within category 3U (IQOA classification). These engineering structures, owned by the highways agency of Isle-sur-la-Sorgues, are stone bridges with serious defects such as mouldings and tympanum walls becoming detached, cracks and fractures, impermeability problems, encroachment of vegetation, and so on.
