This weekend, Monaco will see significant traffic disruptions due to two major events: the Blue Economy and Finance Forum at the Grimaldi Forum and the State Visit of French President Emmanuel Macron. Both events will bring heightened security measures and widespread restrictions affecting vehicles, pedestrians, and public transport.
On Saturday, June 7 from 6:00 to 20:00 and Sunday, June 8 from 6:00 to 17:00, Avenue Princesse Grace will be closed to traffic in both directions between the Portier and Rose des Vents roundabouts. Access will only be granted to residents of the nearby buildings—such as Emilie Palace, La Réserve, Houston Palace, Columbia Palace, and the ruelle St Jean—and only via Rose des Vents. Additional rolling road closures may occur across Monaco during these periods, particularly around Monaco-Ville, Monte-Carlo, and Larvotto, depending on the movement of official delegations. Traffic entering the Principality via the motorway tunnel or Moyenne Corniche is also expected to be heavily affected.
On Sunday between 12:30 and 16:00, Boulevard Louis II will be closed entirely to vehicles and pedestrians between the Portier roundabout and the Pattaya turnaround. Parking access to both the Louis II and Monte-Carlo Star car parks will be suspended during this window. Authorities have stated that these measures may be adapted on the day in response to security needs.
Pedestrian access on Avenue Princesse Grace will be limited, with the lower, seaward-side pavement off-limits to the public except for those with accreditation. Foot traffic will be redirected to the upper pavement or through Mareterra. Boulevard Louis II will also be inaccessible to pedestrians during the Sunday closure period.
Public transport will also be disrupted. Bus lines 1, 2, 3, and 4 will largely maintain their usual routes, although Line 1 will be diverted via Avenue d’Ostende on Sunday due to the Boulevard Louis II closure. Line 5 will follow a special Grand Prix-style route, terminating at Place des Moulins and making a return stop at Place du Casino. Line 6 will divert to Saint-Roman via Boulevard d’Italie, also stopping at Place du Casino before resuming its regular route to Fontvieille. The boat bus service will be completely suspended throughout both days of the forum and will resume on Monday, June 9.
With high-profile events and tight security, authorities are urging residents and visitors to plan ahead, expect delays, and follow police instructions throughout the weekend.
