The bridge forms part of the Bilbao eastern bypass. It is an arch bridge with a prestressed concrete upper deck, 316 m long with 14 spans, the seven central spans resting on an arch with a span of 148 m and a height of 50 m. The deck is 25 m wide and has four traffic lanes with their corresponding pavements, shoulders and median. The deck is 25 m wide and accommodates four carriageways with their corresponding pavements, shoulders and median.º

The section of the arch is a tricellular box with a variable edge, which is built by successive segments of its full width and 6 m long each. The bridge was built by cantilevering the arch together with the piers and deck, provisionally triangulating the structure with braces and directing the forces towards both abutments, which are in turn anchored to the rock.
