The Garonne divides as it flows under the Saint-Michel bridge, creating the two branches that surround Ramier island. Huge complexes have been built in the middle, taking advantage of the wide-open space available: the Parc des Expositions (Exhibition Centre), the Stadium, and Ramier Park. The two branches of the river come together again to the south, near the Empalot area, which is close to the Science faculties and Pech-David hill.
