The port city of Progreso, in the Mexican state of Yucatán, boasts of the longest pier in the world. Built with reinforced concrete, the pier juts out into the Gulf of Mexico for a distance of 6.5 km, and looks more like a bridge to some distant land. The unusually long length is necessary to allow large ships to dock since the Yucatan coast is very shallow. The limestone shelf that forms the Yucatán Peninsula falls away at such a shallow angle that it is literally kilometers before the water is deep enough to accommodate cargo vessels. Passengers disembark at the end of the long pier, and then take a free shuttle or a taxi cab to the shore and into town.

The pier was originally 2,100 meters long and was constructed between 1937 and 1941, replacing a wooden pier that was built in the beginning of the last century. In 1988, an additional 4,000 meters was added to its length increasing the pier’s cargo and container vessels handling capacity.
