Ecatepec Finds at Least Two Kilometers of Caverns Beneath Adolfo López Mateos Avenue, Requiring Another 100 Million Pesos to Remove Risks

Workers began resurfacing Adolfo López Mateos Avenue in Ecatepec and discovered at least two kilometers of caverns beneath the road. Some of the underground voids measure up to six meters high, turning a road rehabilitation project into a larger effort to prevent a potential danger to residents.

Mayor Azucena Cisneros Coss said the cavities likely formed after drainage infrastructure deteriorated and the ground eroded. She called the situation a latent risk for many neighbors and said the municipality would need about 100 million pesos more to remove it.

“

We have found a very serious problem that we have to solve.

The avenue, also known as R1, stretches for 11 kilometers and crosses 26 neighborhoods. Built in the 1960s, it has received only one major intervention, according to the mayor, and has deteriorated through years without adequate maintenance.

Cisneros blamed decades of neglect and alleged that public officials failed to invest in water and drainage networks. “We have found a very serious problem that we have to solve,” she said, adding that she expected support from Governor Delfina Gómez Álvarez and President Claudia Sheinbaum Pardo. The municipality has made progress on its water network, she said, but still needs to address drainage so residents can live without fear.

“

It is a latent risk for many neighbors and we will, of course, tackle it with everything we have.
