Circuito Interior


The Circuito Interior Bicentenario or more commonly, Circuito Interior or even more simply Circuito, is a 42-km-long urban freeway and at-grade boulevard, forming a loop around the central neighborhoods of Mexico City. It was built starting in 1961. The Circuito Interior received the appellation Bicentenario after a renovation that took place in 2010, Mexico's bicentennial year.

History

In 1951, 8 km of the Río Consulado river's course between the :es:Monumento a La Raza|Monumento a La Raza and Mexico City Airport was put underground and the route was opened as a highway.
Regent Ernesto P. Uruchurtu decided upon the routing underground of more stretches of the rivers Río Consulado, Río Churubusco and Río de la Piedad. An 18-km route was completed in 1961. In 1974 the Circuito was extended to the south and west, which according to sources at the time resolved 50% of the intersections with severe traffic congestion, with the support of the additional controlled-access roads Río San Joaquin and Parque Vía, together with the construction of the feeder roads Tacuba, Los Hongos and Chapultepec. Its eastern and western parts were finished in 1976.
