As reported by Monaco-Matin, intensive stabilisation work has continued this week on the retaining wall straddling the border between Monaco and Beausoleil, following the precautionary evacuation of three residential buildings due to a potential risk of collapse…
Engineers are currently focused on reinforcing a weakened section of the 100-metre wall, where monitoring sensors detected abnormal stress levels. Tie rods have been installed to redistribute pressure and secure the structure, with particular care taken to ensure that the intervention does not create secondary instability elsewhere along the embankment. Independent experts remain on site, carrying out frequent measurements as works progress.
On the French side, Beausoleil has moved quickly to adapt public services while maintaining continuity for residents. A temporary 7.5-tonne weight limit has been introduced on Boulevard Guynemer to reduce stress on the area, without disrupting essential services. Household waste collection continues using lighter vehicles, while public transport operations are maintained through the use of minibuses.
Energy and sanitation networks are also under close surveillance, with electricity, gas and water supplies monitored jointly by local authorities to prevent any disruption linked to the works. Officials have stressed that no outages are anticipated at this stage.
On the Monegasque side, the government has confirmed that the security perimeter remains unchanged and that there is currently no justification to extend evacuations. Authorities on both sides of the border continue to coordinate closely, with safety remaining the overriding priority as reinforcement work advances and further technical assessments are awaited.
