After completion of the 4-month design phase, construction work will begin in March 2012 and will last 18 months.

Major maintenance and refurbishment, standard maintenance and upkeep of the bypass will be entrusted, for 15 years, to Colas Rhône-Alpes Auvergne, which will be responsible for road surfaces and equipment, and to Bouygues Travaux Publics Régions France, which will be responsible for civil engineering structures.

The Allicso project is focused on environmental protection, in particular reducing impacts on biodiversity, and involves the participation of local SMEs and the employment of people without access to jobs.
