The A28 Rouen Alençon motorway construction

On 27 October 2005, for the first time in France, a 125 km section of motorway was open in one piece. The involvement of the teams, the importance of the resources deployed and the excellent coordination of the stakeholders had made it possible to build the 125 km in just 28 months, which was also a first at this time. Thus, ALiS was able to exceed its contractual commitments by delivering nearly 2 months before the scheduled date!
