This project to design, build and operate approximately 16 km of 2 times 2 lanes motorway linking Machilly and Thonon-les-Bains (A412), together with the development of public transport services, is part of the plan to open up the Chablais region. It will serve and open up the area south of Thonon-les-Bains starting from the Annemasse‑Geneva conurbation and the A40 motorway, improving links between the region’s major attractions by making journey times shorter and more predictable, and enhancing user safety.
This 55-year concession will not receive any subsidies from French government or the Haute‑Savoie department. In addition, the winning bid from the prospective concession operator includes a pricing policy designed to encourage local travellers to use the new motorway, in particular for commuting to work.
Eiffage is determined to create resilient and sustainable infrastructure that will create value for Chablais and its inhabitants and will draw on its expertise in responsible regional development, going beyond regulatory requirements to ensure the environmentally sound implementation of this ambitious project. This approach will promote and support agricultural production in the Chablais area as part of a conscious policy of biodiversity protection and the restoration of ecosystem services. The infrastructure is designed to anticipate and address new climate constraints, incorporating innovative low-carbon construction methods from the design phase onward. It is also supporting the development of complementary alternative modes of transport, with the creation of a cycle route running the whole length of the motorway and the installation of carpool parking areas equipped with electric vehicle charging points. Operation of the motorway will benefit from the Group’s experience and strong local roots in Haute‑Savoie, where it already operates the AREA and ADELAC concessions.
