The Almodóvar Bridge is the first of several structural works forming part of the new Cordoba-Sevilla motorway. The construction procedure adopted—cantilever method by means of precast sections—is very interesting and will be used also for other similar bridges. The bridge structure, with its two approach viaducts, consists of a Gerber beam of prestressed concrete resting on two piers, including a central span of 70 m and two side cantilevers of 35 m. The suspended span, 30 m long, and the two approach viaducts are constituted by precast prestressed beams. The central cantilever arms of the Gerber beam are constructed by means of precast sections which are subsequently connected together by prestressing bars. The article describes the design principles, the bridge structure as well as the methods of construction.
