The last-mentioned line also gives indirect connexion with the port of Coatzacoalcos, and the Mexican Central, via San Luis Potosi, with Tampico.
Of the principal ports on this coast, Matamoros, Tampico, Tuxpan, Coatzacoalcos and Frontera are on rivers, which are obstructed by bars.
Tampico and Coatzacoalcos, however, have been improved by breakwaters or jetties, and the deepening of the Channels across the bars, into safe and commodious harbours.
This line crosses the Isthmus of Tehuantepec from Coatzacoalcos (officially Puerto Mexico) on the Gulf coast to Salina Cruz on the Pacific coast, and has been under construction many years.
The larger ports for foreign trade are Vera Cruz, Tampico, Progreso, Carmen and Coatzacoalcos on the Gulf coast, and Guaymas, La Paz, Mazatlan, Manzanillo, San Blas, Acapulco and Salina Cruz on the Pacific coast.
Some of these - Vera Cruz, Tampico, Coatzacoalcos, Salina Cruz, Manzanillo and Mazatlan - have been greatly improved with costly port works.
Legend tells stories of his teaching men picture-writing and the calendar, and also the artistic work of the silversmith, for which Cholula was long famed; but at last he departed, some say towards the unknown land of Tlapallan, but others to Coatzacoalcos on the Atlantic coast on the confines of Central America, where native tradition still keeps up the divine names of Gucumatz among the Quiches and Cukulcan among the Mayas, these names have the same meaning as Quetzalcoati.
The streams flowing northward to the Gulf coast are the Coatzacoalcos and Papaloapam with its tributary, the San Juan, all flowing across the state of Vera Cruz.
Two important railway lines traverse the state - the Tehuantepec (trans-isthmus) line between the ports of Salina Cruz and Coatzacoalcos (Puerto Mexico), and the Mexican Southern line (narrow-gauge) from Puebla to Oaxaca, with branches to San Geronimo on the Tehuantepec line with the Guatemalan frontier as its destination, and toward Puerto Angel on the coast.
