History
The first bridge across the Orinoco River, the Angostura Bridge at Ciudad Bolívar, Venezuela, was completed in 1967. The first powerline crossing of the Orinoco River was completed in 1981 for an 800 kV TL single span of 1,200 m (3,900 ft) using two towers 110 m (360 ft) tall. In 1992, an overhead power line crossing for two 400 kV-circuits was completed west of Morocure (between Ciudad Bolívar and Ciudad Guayana). It had three towers, and the two spans measured 2,161 m (7,090 ft) and 2,537 m (8,323 ft), respectively. In 2006, the Orinoquia Bridge was completed near Ciudad Guayana.
