Crossing from the 15th to the 16th Arrondissements, you may walk the Bir-Hakeim bridge, made popular by the film Inception. This bridge is an huge two-tier structure, including foot bridge, a metro line viaduct, and motorway. It is exquisitely simple with huge pillars and a very definite vertical feel. The Inception hat reflects these clean lines knit with a simple cable and rib design.
