In September and October 2022, the periodic detailed inspection of the Bec and Risle viaducts was carried out. This inspection was carried out at night in order to limit the inconvenience to customers and with the help of a negative walkway (see photos).

This inspection was completed in November 2022 by the use of a drone (during the day) to inspect all the piers and headers of the 2 viaducts.
