The road was partially opened on 9 December 2003 for traffic entering from local junctions, then fully opened on 14 December 2003 The historical investment structure of the project differs greatly from the present position. The original concession was held by a consortium of Trafalgar House (Kvaerner) and Italstat (Autostrade). The Kvaerner share passed to Macquarie when Kvaerner was restructured in 1999. Macquarie then bought out the Autostrade share when the project was refinanced in 2006
