Puente de la Unidad

Puente de la Unidad or Viaducto de la Unidad is a cable-stayed bridge designed by Oscar Bulnes that crosses the Santa Catarina River and connects the cities of Monterrey and San Pedro Garza García in the Mexican state of Nuevo Leon. It is part of a circuit called "Circuito La Unidad", which would consist of the interconnection of a series of Avenues.

History

It was finished in 2003 and has been controversial even before its completion because the river it crosses is dry almost all year long, and the cost of building this 4 lane cable-stayed bridge would be the same as for building a 6 lane conventional bridge. Frequently it was argued that the costly bridge would aid a relative few, versus spending the money for the rapid transit system of Metrorrey.
