Bridge over the reservoir of Oliana at the Segre river. Spans: 50+66+110+66 m. Ring Oliana-Coll de Nargó from the C-14 road. Sant Ermengol, bishop of La Seu d’Urgell, was a great builder of bridges. Died building the bridge of Bar in 1035. It was customary for centuries in Catalonia do a prayer to the saint before crossing a bridge. In project the assembly of the central stretch was planned by flotation and lifting, 2005 was a dry year and there was not enough water in the reservoir when we planned the assembly.
