The design and construction of cable‐stayed bridge over Bouregreg River, Morocco.

The Bouregreg cable‐stayed bridge is located at Rabat‐Salé‐Kénitra, Morocco. It forms part of the new 41.5 km Rabat motorway bypass around the city of Rabat and will improve traffic congestion in Hay Riad, the capital's western residential suburb. This bridge has a total length of 951.66m, of which the main bridge is a cable‐stayed bridge with spans arrangement of 183+376+183m and a total width of 29.82m. The main girder of cable‐stayed bridge uses double pre‐stressed concrete edge girders, connected with steel cross beams and concrete slab. The concrete pylon consists four separate curve legs, which forms a traditional pointed‐arch on the top of pylon. This paper mainly describes the structural design features and construction of the cable‐stayed bridge, and highlights some innovations of the design and construction, such as the connection between cable and pylon legs, steel cross beam and concrete edge beams, the concreting sequence of main girder and tension of stayed cables.
