This weekend, residents and visitors in Monaco are advised to brace for significant traffic disruptions as the Principality hosts two high-profile events: the Blue Economy and Finance Forum at the Grimaldi Forum and the State Visit of French President Emmanuel Macron. These simultaneous events will trigger enhanced security protocols, leading to widespread restrictions impacting all modes of transport – vehicles, pedestrians, and public buses.

Rolling Road Closures & Broader Impacts:
- Expect additional, unannounced rolling road closures across Monaco, particularly in Monaco-Ville, Monte-Carlo, and Larvotto. These will be implemented dynamically based on the movements of official delegations.
