The construction project of the access road to Soto de Ribera Asturias’s village, includes a cable stayed bridge that overflies the Caudal river and the goods rail tracks. The bridge is located next to the existing thermal power plant settled in the village.
The bridge responds to the cable stayed typology with a two double T beans composite deck. The deck is 186 meters long and 11.65 meters wide and is supported by 28 stays anchored to a large pylon tower of composite section of 57.50 meters high, standing in the middle of the bridge.
The deck is supported at both ends on concrete abutments, and in the midpoint between the supports, where is located the pylon tower.
Given the characteristics of the environment and the existence of the river and railroad tracks under the bridge, the construction process is developed through successive cantilevers.
On the railroad side, the use of temporary supports serves to hold the deck until from the other side of the river the cantilevered sections of the deck placed in successive stages, and supported by the stays arrive to this point. Therefore, the deck is built on the river without interference and preserving intact the watercourse and river banks.
