World's Most Spectacular Pedestrian Bridges
Puente de la Mujer, Buenos Aires
Architect Santiago Calatrava's "Woman's Bridge" on the Rio de la Plata is female by association; the surrounding streets are named for noteworthy women such as human rights activist Alicia Moreau de Justo. The bridge faces a new crop of trendy hotels, restaurants, and condos in Puerto Madero—and can take some credit for inspiring the neighborhood's redevelopment.
Fancy Footwork: With a single mast pointing skyward at a 45-degree angle, the bridge sometimes gets compared to a couple doing the tango. We don't quite see it, but in Buenos Aires, tango dancers are never far away, especially on the streets of San Telmo.
