The new Anne-de-Bretagne Bridge in Nantes is more than a symbol of sustainable urban transformation; it is the protagonist of a remarkable maritime journey. Built entirely in Monfalcone, Italy, its massive steel deck, measuring 150 meters in length, 42 meters in width, and weighing over 2,200 tonnes, is traveling across Europe in one single piece. Its route takes it through the Adriatic Sea, the Mediterranean, the Bay of Biscay, and finally up the Loire River to the heart of Nantes.

This extraordinary convoy was chosen to avoid nearly 200 heavy truck trips, demonstrating both impressive technical expertise and a strong commitment to reducing environmental impact. Once installed, the bridge will become a new landmark for the city: a large low-carbon “bridge square” designed to carry tramway lines 6 and 7, offer generous paths for cyclists and pedestrians, and create inviting public spaces overlooking the Loire. It reflects the city’s vision of architecture that serves ecology, mobility, and community life by uniting innovation, sustainability, and beauty in a single monumental gesture.
