Coatzacoalcos has been a transportation hub for hundreds of years. It is connected via air, water, road, and rail to the surrounding region and the rest of the world.
The Minatitlan/Coatzacoalcos National Airport is 15 kilometres (9.3 mi) away in Cosoleacaque and has been an international airport since August 2006.
The Port of Coatzacoalcos is an international port of entry that provides transhipment of oil and petrochemicals. After an upgrade to the railway along the Tehuantepec Route was opened in 1907 by Porfirio Diaz the port saw an increase of shipping via the Isthmus of Tehuantepec, particularly from the American-Hawaiian Steamship Company. The port saw a decrease in traffic after the opening of the Panama Canal from 1914 on, but traffic has started to build up since the oil boom of the 1970s.
