This report sets out the main features, from a point of view of design and construction, of the structures that belong to the following works: - Railway bridge over the Manzanares River and M-30, belonging to the Atocha-Villaverde (Madrid) section, and consisting of two twin bridge decks with five spans of 25, 37,37,25 m of cleareance respectively. - Bridge belonging to the Kukularra Interchange, corresponding to the point where two branches cross over the Ugaldebieta mainline, forming a three-level intersection (Bilbao). These are two bridges with significant curvatures in plan, having a bicellular caisson cross-section, and with spans of 30,42 and 30 m and 20,32,20 m of cleareance respectively. - Bridges across the rotary that forms the intersection of CN-II with GE-533 and GE-672 (Gerona). These are two structures with two spans, having 38,5 and 18 m of cleareance respectively, with the compensating span forming part of the corresponding access-embankment. - Bridge over the Guadalquivir River, corresponding to the point where CN-321 crosses over said river in the place known as Puente del Obispo (Jaen). It consists of a structure of three spans with 45, 90 and 45 m of cleareance respectively, constructed by the cantilever method.
