Nantes is transforming
Nantes has been getting a major makeover since 2024.
The city is currently undergoing extensive public works, particularly around Île de Nantes (Quai de la Fosse and the Pont Anne-de-Bretagne bridge). Tram Line 1 will be temporarily suspended from mid-June to late August 2026. The city centre and Parc des Chantiers – Machines de l’Île will remain accessible, thanks to replacement buses and to the pedestrian and cycling routes that will continue to be open. Park-and-ride facilities are available to drivers.
