The Autódromo Hermanos Rodríguez (“Rodríguez Brothers Racetrack”) is a permanent 4.4KM race track located in Mexico City, Mexico. Named after the two Rodríguez brothers, both whom died racing (Ricardo at the track), the facility has been in operation since 1962. The track is located within the public park of the Magdalena Mixiuhca in northeast Mexico City, and the Government also own it. Starting that year, it held a non championship Formula 1 round, which continued until the 1970′s when it had to be stopped due to overcrowding and safety fears. In 1986 the track undertook a redevelopment, to improve the pit facilities and the safety, however the track stayed the same. Looking at the road course, it is still the same 4.4KM, 17 cornered track as it was when built, and there are no plans to change it in the foreseeable future. As well as Formula 1, Nascar and the now defunct A1GP also took place at the venue. Nascar use a smaller layout which is the more common layout today. It also has a 1.6 mile oval, which has one banked corner and one flat, as it cuts away from the main track. It’s used for some of the lower Nascar series, including the Nascar Mexico T4.
