The Ecological Peripheral Ring is a ring road in the city of Puebla, in Mexico. It is an arm of federal highway 190 (Mexico-Amozoc) that allows it to go around a large part of the metropolitan area of ​​Puebla. With an approximate length of 40 km,[1] it forms an arc that is linked to Highway 150D") (Mexico-Veracruz) by two junctions, respectively at the northwest and east ends of the urban area, surrounding it to the south.

The Ecological Peripheral was conceived in 1993 as part of the Angelópolis Regional Development Plan.[2]​ This planned to grow and modernize the city, as well as speed up vehicular flow through a fast track that would connect the Mexico-Veracruz highway with the south of the city, freeing it from through traffic.[3]​.

In a first phase, the Ecological Periférico was inaugurated in 1997, during the governorship of Manuel Bartlett.[4]​ It initially included the west and south route, from Highway 150D at the height of San Francisco Ocotlán to Avenida José María Lafragua/Prolongación 24 Sur. Successive extensions extended it towards the east, first to Valsequillo Boulevard, then to federal highway 150") (Puebla-Antón Lizardo "Antón Lizardo (Veracruz)"), and finally until it connected again with highway 150D at Chachapa.

Currently, it has six lanes (three in each direction) along almost its entire length. However, in the past it only had four lanes without shoulders as it passed through the west of the city.[5]​.
