Safety work on the Roche Pourrie cliff face along the RD 94 in the Drome department.

Facing rockfall risks on the RD 94, the Drôme Department is investing 2.5 million euros to permanently secure the Roche Pourrie cliff near Saint-May.

These significant works aim to ensure the safety of road users, who are particularly exposed to rockfall phenomena exacerbated by climate change. The schedule has been organized to minimize disruptions to travel, local economic activity, and tourism, especially during the year-end and February holiday periods.
Continuous monitoring of the cliff is ongoing, with detection and alert systems remaining fully operational to anticipate any incidents.
