The Ponte alla Carraia is a five-arched bridge spanning the River Arno and linking the district of Oltrarno to the rest of the city of Florence, Italy. To the west is a weir, the Pescaia di Santa Rosa, and the Ponte Amerigo Vespucci, and to the east is the Ponte Santa Trinita. The piazzas on either bank are the Piazza Nazario Sauro (south) and the Piazza Carlo Goldoni (north). At the northernmost column of the bridge a family of coypus live in a dam.
