The intervention involved expanding the 32 km stretch between Modena Nord and Bologna, which sees peak traffic of up to 168,000 vehicles per day (including around 48,000 lorries and buses), from 3 to 4 lanes plus a hard shoulder. This stretch is the point of intersection of the two main highways connecting northern (A1 and A22) and southern Italy (A1 and A14).

After sharing the planning decisions with the Local Authorities, the authorisation phase of the project was launched, which concluded with the Services Conference in November 2002.

The 4th northbound lane was opened to traffic on 23 December 2005, 8 months ahead of schedule.

The 4th lane was fully opened to traffic on 31 March 2006, approximately 5 months ahead of schedule.

The 3 lanes remained open to traffic in each direction throughout the execution of works, with the exception of some necessary resurfacing phases.

Local works

These interventions, financed and planned by Autostrade per l'Italia, concern the construction of the North-South Ring Road in San Cesario sul Panaro, the installation of noise barriers for a total of 15 km and the expansion of the Modena Ring Road, the plan for which is currently being approved by the Authorities.
