On 30 December 2000, Eiffage's subsidiary Norscut signed a concession contract with the Portuguese government to design, build, finance and operate the future A24 motorway (or SCUT do Interior Norte) running through the Porto vineyards to link up Viseu with Chaves.
The infrastructure took over 6 years to complete. During this time, building consortium Norinter's builders excavated 26 million cubic metres of earth and built 130 engineering structures including 37 viaducts, among them Corgo and the longest, Vila Pouca de Aguiar. The 155 km motorway also required 1.3 million tonnes of asphalt mix, with most of the aggregate used coming from Eiffage Group's Adifer quarry.
Norscut's last stretch was commissioned on 24 June 20017, in the presence of Portuguese Prime Minister José Socrates.
