CDG Express is a 32 km rail link project (including 8 km of new track) in the « Île-de-France » region, between « Paris East train » station in Paris and « Paris-Charles-de-Gaulle » airport.

The CDG Express route starts at the East station with a dedicated platform and tracks. CDG Express trains arrive and depart from the platform on 3 tracks (tracks 2, 3, 4), tracks 3 and 4 are the platform tracks and the 3rd track is used as an emergency track.

The aim of this project is the creation of three rail bridges at « Mitry-Mory », a 1.5 km tunnel under the tracks at « Roissy », the replacement of railway equipment (platforms, etc.) at Drancy », « Aulnay », « Le Blanc-Mesnil », « Villeparisis » or « Le Bourget », major civil engineering works near the tracks at « Saint-Denis », the renewal of bridges and the crossing of the « Porte de la Chapelle » by viaduct.

Our mission focuses on the covered and open trench of lot C and on the RAPL-type structure of lot C.
