The Western Strasbourg bypass A355 in eastern France was commissioned last week. Recognised as a public interest on 23 January 2008, this 24 km long road represents the most extensive motorway project undertaken in France in recent years. VINCI Autoroutes, as contracting authority, financed the EUR 561 million cost of the project and will also operate and maintain the new motorway as part of a concession contract spanning 54 years.Commissioning this motorway marks the culmination of a project launched in October 2018 after three years of studies and preparatory work, which involved 6,000 people and over 300 companies, a third of which are based in the Alsace region. The design and construction work was entrusted to a consortium of companies made up of VINCI Construction (Dodin Campenon Bernard, lead company, VINCI Construction Terrassement, VINCI Construction France and Eurovia), VINCI Energies (Cegelec Mobility) and Ingerop Conseil & Ingénierie.By rerouting hauliers from the A35 urban motorway, the A355 will ease congestion around the city of surrounding area, saving up to 10 million hours of time lost each year, and will facilitate the expansion of shared, low-carbon mobility solutions, thereby helping to reduce air and noise pollution and improve the quality of life for local residents.Its design, construction and operating model makes the A355 a ground-breaking project in road transport infrastructure, in terms of ecological transparency and environmental integration. For example, 1,315 hectares of land have been the subject of environmental offsetting measures – 4.5 times the total footprint of the finished motorway – and 130 wildlife passages were built, representing one passage every 200 metres, which in relative terms is 20 times more than on other motorway networks in France.
