A consortium led by Vinci Construction has won a €193m contract to build a 6.7km-long viaduct for metro line 18 of the Grand Paris Express, which Vinci says is the largest urban mobility project currently underway in Europe.
The viaduct will be located towards the middle of line 18, connecting Massy-Palaiseau and the future overhead CEA Saint-Aubin station.
Line 18 will connect 10 stations between Orly airport and Versailles, and is intended to boost development of the Plateau de Saclay with its cluster of research labs, university campuses and higher education establishments.
Vinci said the 30-month project will employ 400 people at peak.
Work on the first section of line 18 has begun and is being carried out by another consortium, also led by Vinci Construction.
The group is involved in other works packages of the Grand Paris Express which, when fully complete in 2030, will add four lines to the city’s rail network, comprising 200km of track – 90% of which will be underground – and 68 stations.
The consortium building the viaduct is composed of Vinci Construction Grands Projets as lead company, Vinci subsidiaries Dodin Campenon Bernard, Chantiers Modernes Construction and Freyssinet, and Razel-Bec, subsidiary of the Fayat Group.
The contract was awarded by Société du Grand Paris, the state agency established to deliver the Grand Paris Express.
