Viaducto Miguel Alemán is a crosscutting freeway, opened in September 1950, that runs east-west across the middle of Mexico City. In the center of the road is a river encased in cement to control flooding. Metro Viaducto is named after this road.
The Viaducto was originally planned by architect Carlos Contreras as early as 1925, together with other major roads such as the Anillo Periférico.[1]
