They began work at seafor the construction of protective reefin the ‘La Vesca’ area of ​​Sanremo, affected by the works for the settlement of the landslide movement which, for years, has been holding road traffic in check to the east of the city of flowers.

The intervention is among the most awaited to avoid the hill landslide which has been going on since the end of the 19th century and, the construction of a protective cliff to limit sea erosion is fundamental for the entire project. We remember that Anas is carrying out works worth around 13 million euros with a piling system that will avoid the collapse of the Aurelia. The Common, however, is building the cliff with 2.4 million thanks to regional funds. There is another 3.8 million intervention planned, again by the municipality with state funds.

According to the reports of the technicians appointed by the Municipality, the reactivation of landslides it dates back to 2010 when the first breakage of the Roya pipeline occurred with a landslide along the cycle path. Since then the phenomenon has continued to worsen in the event of heavy rain.

The ground movement, now finally stopped thanks to piling works, was quantified at around 30-40 millimeters per year with the peak of 80 millimeters reached in 2014 due to heavy rains. Even the Aurelia, in the ‘La Vesca’ area, has shown a progressive and widespread subsidence in recent years, which has caused the partial collapse of a part of the roadway (particularly evident on the downstream section, at the junction between the shelf upstream of the existing support work and the embankment behind).

The work began with the presence of ‘pontoon’, consists in the construction of a cliff made of natural boulders placed at the foot of the slope in order to limit the progressive erosion of the coast and guarantee an increase in the forces resistant to sliding while leaving the destabilizing forces unchanged. The intervention will produce a hydraulic and hydrogeological risk mitigation present in the area in such a way as to minimize the risk of triggering further disruptions.

In recent months the works have seen 270 perforated piles cast over 140 meters with a diameter of 800 mm and 20 m long as well as 500 40 meter tie rods. Prior to this, work had been carried out on the trenches for water regulation.

The works continue quickly and, from Palazzo Bellevue, we hope to be able to reopen the Aurelia to two-way traffic by the end of 2025. A date to be taken with a pinch of salt, given that the works are continuing but the construction of the retaining wall on Via Duca d’Aosta will be needed, which will guarantee the complete reopening of the road.
