In 1957, Venezuelan civil engineers Juan Francisco Otaola Pavan and Oscar Benedetti, working with Italian designer Riccardo Morandi, won the competition to span the Tablazo Strait at the outlet of Lake Maracaibo with a cable-stayed bridge unlike anything the country had attempted. Otaola insisted that at least 50 percent of the workforce and contracting companies be Venezuelan. When the General Rafael Urdaneta Bridge opened in 1962, it stretched 8.678 kilometers from shore to shore, connecting the city of Maracaibo to the rest of Venezuela for the first time by road. It remains one of the longest concrete cable-stayed bridges in the world.
