Monaco awaits Nice Métropole move on border traffic fixes
By Zak Jackson, MonacoViews Editorial
Preliminary surveys are under way for a trench on the Moyenne Corniche as Monaco's government presses the Métropole Nice Côte d'Azur to update data on the last roundabout before the frontier.
Engineers are carrying out preliminary ground surveys on the Moyenne Corniche ahead of a planned trench, or trémie, designed to ease one of the most congested approaches into the Principality. The project has long been cited by residents and commuters as a priority for anyone crossing daily between Beausoleil, Cap d'Ail and the Monaco side of the border.
Alongside that work, the princely government has formally asked the Métropole Nice Côte d'Azur to update its traffic data before any redesign of the last roundabout drivers encounter before entering Monaco. Officials want current figures on vehicle flow and peak-hour bottlenecks rather than relying on older studies, a step seen in Monaco as essential before committing to a new junction layout.
For property owners and residents in the border zone, from Carnier to the Fontvieille approach roads, the outcome will shape daily commuting times for years to come. The next move now rests with the French side, with Monaco's services having completed their part of the groundwork and awaiting fresh data from the Métropole before any construction timeline can be set.
