A land system of more than 4.03 miles was developed, the ventilation of a tunnel of more than 600 meters and a fire network of more than 0.3 miles, in addition to the electromechanical installations necessary for the 8 stations contemplated in this project. Construction that covers more than 4.9 miles and is part of the most important transport network of the Monterrey Metropolitan Area. About 600 plans were made with the engineering necessary to build this great project.
Nearly 90,000 pieces of support were used only for the power wiring system in 13.2 KV and ground, if placed one after another would be a distance greater than that between Monterrey and Saltillo.
The main challenge for GP Construcción in this project was the interference with the existing infrastructure and the complexity of some disciplines.
