longest pier in the gulf
4 miles long, the Progreso Pier is one of the longest in the world. The pier that extends from the shores of Progreso, YucatÃ¡n into the deep waters of the Gulf of Mexico is among the longest such structures in the world. Located in a port city in Mexico in the state of YucatÃ¡n, the pier was built for docking large cargo and passenger ships. The pier hasnât always reached such great lengths.
