New pedestrian bridge near Boulogne-Billancourt, France

The town of Boulogne-Billancourt that borders on the 16th district southwest of Paris is located close to the Seine River. Until recently, there was no direct connection between Seguin Island and the town of Sèvres on the left side of the river.

Consequently, a new, 97 m long and 5.7 m wide pedestrian bridge was built over the Seine River.

The completely pre-assembled pedestrian bridge weighs 360 t

The steel structure weighs 360 t and was completely pre-assembled in Lauterbourg. Afterwards, it was transported to the installation site on a barge.

On the left river bank, the bridge abutment is being erected between a railroad track and the Seine River. Due to the limited available space, the crane that was needed for construction work was mounted onto a barge and anchored at the river bank. The two reinforced concrete bridge bearings at the river bank rest on approximately 23 m long bored piles.

For the abutment on the left river bank, Technique Béton supplied several high quality products in order to ensure a long service life of the bridge bearings, e.g. concrete spacers for the correct positioning of the reinforcing mesh and a vegetable mould release agent for the formwork. This product has been developed in response to the CLP Regulation (Classification, Labelling and Packaging). In addition, a special wax was applied with high precision on the architectural formwork.
