Monterrey’s modern, efficient metro system Metrorrey currently consists of two lines. Elevated Línea 1 runs from the northwest of the city to the eastern suburbs, passing the Parque Fundidora. Línea 2 begins underground at the Macroplaza and runs north past Parque Niños Héroes into the northern suburbs. The two lines cross right by the central bus station at Cuauhtémoc station.
Several metro stations are connected with metrobuses (specialized buses with set stops) to outlying areas. Construction has also started on Línea 3, which will connect Zaragoza station by the Macroplaza to the northeastern suburbs. Work is expected to be completed in 2018.
