- 300,000 containers projected by 2028; 1.4 million by 2033.
- Rail transit means unloading and reloading every ship — extra cost and time.
- No water needed: immune to the droughts that limit the canal.

A $7.5 billion railway across the Isthmus of Tehuantepec promises to move cargo from ocean to ocean in seven hours. Can the Interoceanic Corridor really compete with the canal?
The project
The Interoceanic Corridor of the Isthmus of Tehuantepec (CIIT) modernizes a 188-mile railway between Salina Cruz on the Pacific and Coatzacoalcos on the Gulf — plus ports, ten passenger stations and a future link to the Tren Maya. “We will go from one ocean to the other in seven hours,” promised the government at its launch.
The corridor has already created about 800 direct and 2,400 indirect jobs, in two states where poverty runs deep: 35.7% of Veracruz and 28.7% of Oaxaca live in moderate poverty.

The challenger
Panama Canal
The incumbent
Analysts estimate the corridor could divert around 5% of the canal’s traffic — a complement to Panama, not a replacement.
Beyond the trains
Tax breaks and incentives to attract manufacturers along the route.
New hubs planned for automotive, electronics and textile industries.
Salina Cruz and Coatzacoalcos upgraded to handle ocean-going container ships.
The other side
Indigenous communities of the isthmus, led by activists like Carlos Beas Torres, argue the project advances without real consultation. In April, authorities dismantled the “Tierra y Libertad” protest camp and 44 activists were charged.
“Investment in essential services remains minimal.”
— Carlos Beas Torres, community leader
Quick answers
The Interoceanic Corridor of the Isthmus of Tehuantepec (CIIT): a $7.5 billion, 188-mile railway linking Salina Cruz (Pacific) with Coatzacoalcos (Gulf of Mexico) in about seven hours.
Projections point to 300,000 containers a year by 2028 and 1.4 million by 2033. The Panama Canal handled 14,080 transits and 285 million tons in 2023.
Unlikely. Analysts estimate it could divert around 5% of canal traffic. Its edge: rail needs no water, while drought has cut Lake Gatún levels and limited canal transits.
About 800 direct and 2,400 indirect jobs so far, plus free trade zones and ten industrial parks planned for Oaxaca and Veracruz — though indigenous communities contest the project’s local benefits.
