Salina Cruz is an important seaport city on Mexico's Pacific coast. It is located in the state of Oaxaca. It is the fourth-largest city in Oaxaca. It is also the main town of its municipality, which has the same name.

The city is part of the Isthmus of Tehuantepec region. In 2020, about 76,660 people lived in the city. The whole area, called the municipality, had 84,438 people. It covers about 131.9 square kilometers.

This port became important in the late 1800s. It was the southern end of the Tren Interoceánico (Interoceanic Train). This train helped move goods across the narrow Isthmus of Tehuantepec.

History of Salina Cruz

Salina Cruz was started in 1522 by the Spanish. Pedro de Alvarado was in charge. They named it "Salina de la Santa Cruz." This was because its official founding day was a Catholic holy day.

Salina Cruz is near where the Río Tehuantepec meets the ocean. It is on the Gulf of Tehuantepec. The area did not have a natural harbor. There was only a small village of native people before.

The Mexican government chose Salina Cruz to be the Pacific end of the Tehuantepec National Railway. They built a modern town nearby. They also built an artificial harbor. This was to handle all the ships and goods expected.

Building the Port

The new port opened in 1907. By 1909, many workers lived there. The harbor was made by building two long walls called breakwaters. These walls curved towards each other. They left an entrance 635 feet wide.

Inside, the harbor had two parts. There were also many docks and warehouses. These warehouses had electric cranes. There were also many railway tracks. The port also had one of the largest dry docks in the world at the time. A dry dock is a place where ships can be repaired out of the water. This one was 610 feet long.

The port was designed to move a huge amount of goods across the country. Even before it was finished, four shipping companies planned to use Salina Cruz regularly.
