Why is Mexico City an important transportation hub?

Mexico City serves as a vital transportation hub due to its strategic location in the Mesa Central, which has historically functioned as a natural crossroads for trade between the arid north, the Gulf of Mexico, the Pacific Ocean, and southern Mexico.1

This central role has evolved over centuries:
* Historical Foundation: Ancient trade routes and colonial-era paths for mule trains and carts converged on the city, eventually forming the core of the modern national transportation network.21
* Road and Rail Connectivity: Today, major highways and railway lines from across the country radiate outward from the capital. The city is linked to major regional hubs—such as Puebla, Toluca, and Querétaro—via an extensive network of expressways and toll superhighways.23
* Air Travel: The city’s international airport is a primary gateway for both domestic and international flights, supported by additional regional facilities to manage air traffic.2

Within the metropolitan area, the city maintains a complex internal system, including a heavily subsidized Metro subway and various bus networks, to support its massive population.2
