The Puente Ingeniero Carlos Fernández Casado (also called Barrios de Luna Bridge ) is a motorway bridge as part of the Autopista AP-66 ( Autopista Ruta de la Plata ) over the reservoir of Barrios de Luna in the Spanish province of León , approximately halfway between León and Oviedo .
The cable-stayed bridge , built between 1979 and 1983, is named after the Spanish civil engineer Carlos Fernández Casado (1905–1988). It was planned by the engineering firm Carlos Fernández Casado, SL , founded in 1966 under the direction of Javier Monterola .
At 440 m it had the largest span of all cable-stayed bridges with concrete bridge decks until it was replaced by the Skarnsund Bridge in 1991 and still had the largest span of all bridges in Spain until it was replaced by the Puente de la Pepa in Cádiz in 2015 .
description
The bridge has two lanes in each direction and a walkway outside the stay cables for maintenance personnel.
Their H-shaped reinforced concrete pylons stand with their legs slightly spread outwards on the bank rocks and therefore have different heights of 102.3 m and 117.3 m. The stems of the pylons are connected to each other and stiffened above the deck girder by two cross bars. The span is 440 m.
The carriageway girder consists of a three-cell hollow box made of prestressed concrete , which is stiffened every 4.5 m by transverse discs. Its cover plate is 22.5 m wide, its 14.5 m wide base plate is connected to the cover plate on the inside by two vertical webs and on the outside by inclined webs. The base plate is partially cut out to reduce weight. The construction height of the deck is only 2.5 m. It hangs alone on the stay cables and is not supported on the pylons. Because of the short side spans of only 99 m, it is rigidly connected to the abutments that serve as a counterweight. This is why the deck girder has a movement joint in the middle of the bridge . From each stem of the pylons 28 stay cables are stretched in a fan shape to the main opening and 27 cables to the side opening, making a total of 220 cables.
