Saint-Roman interchange stalls as Monaco awaits French signal
By Zak Jackson, MonacoViews Editorial
The planned Saint-Roman interchange linking Monaco to Roquebrune-Cap-Martin remains stalled as the Principality waits for French authorities to move the project forward.
The future interchange at Saint-Roman, on the border between Monaco and Roquebrune-Cap-Martin, has stalled before construction has even begun. The scheme is considered a key piece of the puzzle for easing road access into the Principality from the east, where the current junctions along the Moyenne Corniche and Basse Corniche regularly seize up during peak hours and major events.
The Monegasque government has completed its side of the preparatory work and is now waiting on a formal response from French authorities before the project can advance. Cross-border infrastructure of this kind requires coordination between Monaco, the French state and local Alpes-Maritimes bodies, and it is this alignment that appears to be missing. Without a clear commitment from Paris or the prefecture, no timeline for construction can be set.
For residents of Roquebrune-Cap-Martin and the eastern districts of Monaco, the delay prolongs daily congestion that has become familiar at the frontier crossing near Saint-Roman. Property owners and businesses in the area have long pointed to the interchange as essential for smoother traffic flow as both towns continue to grow, and the lack of movement on the French side leaves the project's future uncertain heading into 2027.
