1. In regard to water-based transportation, Mexico isn't as developed as the United States. There are seventy-six total seaports and only ten river ports. It's been reported that four of the most frequented seaports are responsible for approximately sixty percent of the merchandise traffic. Two of these popular seaports are called Altamira and Veracruz; these are located in the Gulf of Mexico. Additionally, seaports called Manzanillo and Lazaro Cardenas service the Pacific Ocean. In terms of proximity to the United States, it appears that a seaport called the Rosarito Terminal is closest. The Rosarito Terminal is located near San Diego, CA, just south of Tijuana.
2. Land transportation in Mexico is similar to the United States. The roadway network is extensive, and is actually home to the most paved roads in all of Latin America. The highways and smaller roadways are similar if not identical to those in the US. For the majority of expressways, tolls exist. It's been reported that Mexican tolls are some of the most expensive in the world.
Towards the end of the 20th century, Mexico made the decision to 'privatize' it's railroads. There are metro systems in both Mexico City and Monterrey. There are also smaller railroad systems within Mexico City and Guadalajara. Additionally, a high speed railway from Mexico City to Guadalajara has been proposed but construction has yet to begin. Smaller, passenger-only trains exist throughout the country and are operated by government owned private companies.
Mexico also has a freight-based railway system. This is owned and operated by the national government. While the majority of Mexican rail activity is for freight purposes, passenger trains do exist. Interestingly enough, there are even railway routes that connect to the United States. Before the railway system developed into what it is today, it had been struggling after a major decline during the Mexican revolution.
3. Air transportation in Mexico is important. Throughout the country there is an extensive network of airports. Mexican airports are the most advanced in Latin America; every city with a population of over 500,000 usually has an airport of it's own. Seven of these airports are the most frequented, with about 90% of all Mexican air travel occurring in and between these airports. These top seven include: The Mexico City International Airport, The Cancun International Airport, The Don Miguel Hidalgo y Costilla International Airport, The General Mariano Escobedo International Airport, The General Abelardo L. Rodriguez Intenational Airport, The General Juan N. Alvarez International Airport, and the Lic. Gustavo Diaz Ordaz International Airport. In addition to the international airports, there are approximately seventy domestic airports.
