The Angostura Bridge, opened in 1967 at Ciudad Bolivar, was the sole fixed link across a river so wide and powerful that it had defeated every previous attempt at spanning it. Then, a hundred kilometers downstream, engineers found something unlikely: a small island in the middle of the current, exposed only during the dry season, sitting between two navigation channels. They drove their pylons into it. On November 13, 2006, the Orinoquia Bridge opened, and the Orinoco -- South America's second-longest river -- finally had a second crossing.

Its average discharge fluctuates between 66,000 and 85,000 cubic meters per second, with currents running up to 2.6 meters per second. The r...

Iron ore from the Cerro Bolivar mines, bauxite for aluminum production, and hydroelectric power from the Caroni River's cascade of dams all converge here, making it one of Venezuela's most important industrial centers. Before the Orinoq...

The Orinoco powerline crossing carries high-voltage electricity across the river on towers that rank as the tallest human-made structures in South America. Together, the bridge and the power lin...
