The bridge Carlos Fernández Casado covers the principal arm of the reservoir of Barrios de Luna, at the height of the former bridge of San Pedro de Luna, today covered by high waters. It is a suspension bridge with 440 m of space between its towers, with lateral bays each of 65 m. In carrying out the work the following phases were contemplated: — Counterweights. — Towers. — Braces. — Lintel. — Suspension. — Construction of the board. — Auscultation and control. The bridge is articulated in the center and with free longitudinal movement in order to permit the movements produced by retraction, flow and dilatation. This situation demands the carrying out, in the center of the bay, of a cap which permits vertical gyrations and horizontal displacements along the axle of the bridge and which prevents the rest of the movements. Both the project and the construction have been directed not only toward a viable construction from the point of view of resistance but also to obtain a balanced and esthetic work for the users of the highway.
