The old N-340 coast road between Nerja and Torrox was closed to traffic on Tuesday afternoon after a large rock broke away from the mountainside above and fell onto the carriageway.
No one was hurt in the incident which occurred in the municipality of Torrox, not far from the municipal border with Nerja and near La Restinga beach bar.
It appears that the net fitted to the rockface to prevent rockfalls had broken. Earth and smaller rocks also fell onto the road.
The mayor of Torrox, Óscar Medina, ordered the total closure of the road, although initially one of of the lanes was still open to traffic.
