Interoceanic Corridor of the Isthmus of Tehuantepec

The Interoceanic Corridor of the Isthmus of Tehuantepec (Spanish: Corredor Interoceánico del Istmo de Tehuantepec), abbreviated as CIIT, is a trade and transit route in Southern Mexico, under the control of the Mexican Secretariat of the Navy, which connects the Pacific and Atlantic Oceans through a railway system, the Railway of the Isthmus of Tehuantepec (Ferrocarril del Istmo de Tehuantepec), for both cargo and passengers, crossing through the Isthmus of Tehuantepec. The project includes the modernization and expansion of local seaports, particularly the ports of Salina Cruz (Oaxaca) and Coatzacoalcos (Veracruz), and of the Minatitlán oil refinery and the Salina Cruz oil refinery.
