The Marseille-Fos Motorway crosses the Taronte Canal by means of a structure linked to two interchanges. It comprises a central metal structure between two access concrete viaducts. The length of the whole structure is 874m, the dual carriageway is 14m wide. Details are given of the special installation method used. The access viaducts are in prestressed concrete; they measure 314,50m and 259,50m, the spans being 65m. The piers are made of reinforced concrete and were built with the help of sliding forms. The central part is a metal 300-m long bridge with inclined portal frames. The deck consists of a rectangular box girder, on which rests the slab, which is 30m long. The slab is of the orthotropic plate type. The prefabrication and the transport of the metal units are described (some were transported by rail, others by water), together with the assembling, the lifting of the metal deck, the positioning of the portal frames, safety devices, carriageway joints, painting, surfacing, asphaltic varnish, and polymer-bitumen waterproofing course. /TRRL/
