The A65 motorway links the A62 Bordeaux/Toulouse motorway to the A64 Bayonne/ Pau/Toulouse motorway. It also serves Mont-de-Marsan. The end of the works and the scheduled timeframe for putting the motorway into use required interim rapid inspection reports to be produced.

Features
The initial detailed inspections carried out by DIADES enabled the project manager to put the A65 motorway into operation within the timeframe set by the Client, owing to the fact that the visits and reports, which were carried out in record time upon completion of the works, assisted with post-works acceptance procedures and the finish of the structures prior to the motorway being put into service.
