アルバロ・オブレゴン
This project will extend the line from Mixcoac to Observatorio, where it will connect with Line 1 and it will have three new stations and a length of 3.5 km. The two new stations are Valentín Campa and Álvaro Obregón, both situated in the Álvaro Obregón borough. The totality of the extension is being constructed underground.
