Orinoquia Bridge have a clearance of 41 m above water level and are supported by four 120 m tall H-shaped pylons via two planes of cable stays. Unusually, these spans do not lead directly into each other as at other multi-span cable stayed bridges such as the Millau Viaduct, but are anchored at a fixed point on the mid-stream island. The bridge was built to complement the existing Angostura Bridge and to provide a more direct connection with the important industrial city of Ciudad Guayana. In particular, it was intended to provide for a future rail connection to allow the city's heavy
Millau Viaduct conditions (fatigue, density, texture, adherence, anti-rutting etc.). The 'ideal formula' was found after two years of research. The electrical installations of the viaduct are large in proportion to the size of the bridge. There are of high-current cables, of fibre optics, of low-current cables, and 357 telephone sockets; allowing maintenance teams to communicate with each other and with the command post. These are situated on the deck, on the pylons, and on the masts. The pylons, road deck, masts, and cable stays are equipped with a multitude of sensors to enable structural health monitoring. These are designed to detect the
