The old N-340 coast road between Nerja and Torrox will be closed to traffic for the next month after a large rock broke away from the hillside alongside and fell onto the carriageway below on Tuesday afternoon.
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.
Although one of the lanes was initially still open to traffic, the mayor of Torrox, Óscar Medina, ordered the total closure of the road.
The rock, weighing more than five tonnes, was removed the same night after a hydraulic breaker was first used to divide it into smaller pieces.
Technicians then inspected the state of the carriageway and confirmed that damage had been caused to the road surface.
Medina initially ordered the closure for a week to allow for the rock face to be secured, but having consulted the engineering company which designed the road 40 years ago, decided to prolong the closure to deal with the "complicated nature" of the landscape.
The road will remain closed between km 287.1 and 288.7, with road users advised to take the A-7 to get to Torrox and Nerja.
Heavy rain blamed
Medina blamed the heavy rain in the area over the previous few days which also left its mark on the A-7206 between Algarrobo and Cómpeta on Wednesday night. Rocks fell onto the road which was eventually reopened at midday on Thursday.
Technicians from the Junta de Andalucía have inspected the area and put up barriers to prevent further disruption but warn that netting will need to be installed.
