Viaducto Miguel Alemán is a crosstown freeway, opened in September 1950, that runs east-west across central 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 encased duct that is hosted at the center of the freeway carries waters from the west-city hillsides, specifically from the Tacubaya and Becerra rivers. At the east end of the freeway, the river discharges its waters on the Churubusco river, also encased.
The Viaducto Miguel Alemán is nomenclature-wise divided in three portions:
The Viaducto was originally planned by architect Carlos Contreras as early as 1925, together with other major roads such as the Anillo Periférico.
