The General Rafael Urdaneta Bridge is located at the Tablazo Strait outlet of Lake Maracaibo, in western Venezuela. The bridge connects Maracaibo with much of the rest of the country. It is named after General Rafael Urdaneta, a Venezuelan hero of Independence who was born in Maracaibo. Made of reinforced and prestressed concrete, the cable-stayed bridge spans 8.678 kilometres (5.392 mi) from shore to shore. The five main spans are each 235 metres (771 ft) long. They are supported from 92-metre (302 ft) tall towers, and provide 46 metres (151 ft) of clearance to the water below. The bridge carries only vehicles.
The competition to design the bridge started in 1957 and was won by Juan Francisco Otaola Pavan and his partner Oscar Benedetti, Venezuelan civil engineers and owners of Precomprimido C.A., with the design of Riccardo Morandi, an Italian civil engineer. While Morandi designed the bridge, it was Otaola and Benedetti who made the structural and budget calculations, which in part with Otaola’s demand for the project to be done by at least 50% of Venezuelan companies and workforce, secured the winning bid for the Venezuelan government.[5] Precomprimido’s was the only concrete design out of twelve entries, and was expected to be less expensive to maintain, as well as providing valuable experience of prestressed concrete technology for Venezuela.[4] Precomprimido’s construction was aided by several international companies, primarily Julius Berger as well as Grün & Bilfinger, Bauboag AG, Philipp Holzmann AG, Wayss & Freytag and K Ingeniería.
