Macrolibramiento Section Along Azcapotzalco Edge Is 35% Built

Work on Tramo 0 of the Macrolibramiento Mexiquense, a toll highway section that runs along the edge of Mexico City’s Azcapotzalco borough, has reached 35% completion, according to Roberto Carlos Álvarez Juárez, head of SAASCAEM (the State of Mexico agency that runs its highways, airports and related services). He told El Universal the state expects to finish this section at the end of 2027.

The road was planned almost 20 years ago to link the Toluca Valley with the eastern Valley of Mexico. Only 25.5 kilometers are open today, about half of the 50 kilometers in the plan, and the state has set no date for finishing the whole route.

Where Tramo 0 runs

Tramo 0 covers 10.7 kilometers between Puente de Vigas and avenida 1 de Mayo in Naucalpan, and 3.7 kilometers of it is an elevated viaduct, Álvarez said. Its route follows Calzada de las Armas and Calzada de la Naranja, which mark the boundary between the State of Mexico and the Azcapotzalco alcaldía (borough) of Mexico City. The works touch Tlalnepantla and Naucalpan as well as Azcapotzalco.

Construction on Tramo 0 and on Tramo 4.2 at the other end started in 2024, under the state government of Delfina Gómez Álvarez. Work on Tramo 0 was suspended after complaints from neighbors and restarted in February 2026. Juan Hugo de la Rosa, the state’s mobility secretary, called the project “un paso firme” (a firm step) for mobility in the State of Mexico during a site inspection.

Banobras, the federal development bank, reported investment for both sections in its 2024 annual report.

A project that started in 2004

The highway began as the Naucalpan-Ecatepec toll road. Public records from Infoem, the State of Mexico’s transparency institute, show that the state hired Viabilis Infraestructura in 2004 to build a road from Los Remedios to Ecatepec, under a contract dated Nov. 15 of that year.

• April 2008: construction started.
• Oct. 20, 2009: then-governor Enrique Peña Nieto opened the first stretch of six kilometers, from Puente de Vigas to Calzada Vallejo.
• 2011: the first two stages went into operation, according to SAASCAEM.
• May 2012: Grupo ICA took over Viabilis, which was renamed Autopista Naucalpan-Ecatepec (Anesa), ICA reported to the US Securities and Exchange Commission.
• March 2013: the Vallejo-Pachuca connection, the third stage, opened.
• Aug. 26, 2022: Tramo 4.1, a 2.6-kilometer stretch linking Insurgentes, Gran Canal and the Siervo de la Nación highway, began operating.

What it means for drivers around Azcapotzalco

For people who live or commute along Calzada de las Armas and Calzada de la Naranja, the works on the city’s northwestern border are set to continue for at least another year, since state officials put completion at the end of 2027. Once Tramo 0 opens, the toll road will extend from the current Puente de Vigas end toward avenida 1 de Mayo in Naucalpan.

The full 50-kilometer route is planned to run from the Chamapa-Lechería highway to Ecatepec, passing through municipalities in the west of the State of Mexico.

What comes after Tramo 0

SAASCAEM plans to move to Tramo 4.2 once Tramo 0 is finished. That section covers 3.7 kilometers between avenida Gran Canal and avenida Valle de Santiago in Ecatepec. So far, Álvarez said, only preparatory works have been done there, such as piping the Río de los Remedios underground.

Naucalpan mayor Isaac Montoya Márquez gave a different picture of the next step at a Nov. 4 press conference. He said the city is in talks with the state government over mitigation works and the start of a phase toward Toluca along avenida 1 de Mayo. That phase would reach the junction with Bosque Real, the Chamapa-Lechería highway, the Naucalpan-Toluca highway and the road to La Marquesa, and he said it would open a route from Toluca to Texcoco.

The state’s stated priority for now is Tramo 0, Álvarez said.
