This section of the motorway is fully operational and is composed of two segments: Bucharest – Pitești and Pitești bypass.

The Bucharest – Pitești segment (95.9 km) is the first motorway class road built in Romania and remained the only one for more than 15 years, until the completion of the Fetești – Cernavodă segment on the A2 motorway in 1987. It was constructed between 1967 and 1972 during the communist regime. Various parts of the segment underwent several major rehabilitations: between 1997 and 2000 by the FAT joint venture composed of Italian companies Federici, Astaldi and Todini, between 2002 and 2004 by the Romanian companies Albix Timişoara and Cosar Bucureşti and between 2006 and 2010 by Romanian companies PA&CO Internaţional and Euroconstruct Trading '98. As of November 2015 this is the only segment of the motorway where in rest areas operate motels and restaurants.

The Pitești bypass segment (13.6 km) was awarded in April 2004 to a joint venture composed of Italian companies Astaldi and Italstrade. The segment was opened to traffic during November 2007, having a major role in diverting traffic from the Pitești city centre. An underpass in the Bascov area (north of Pitești) was also built to resolve traffic congestion at the nearby junction of the DN7 and DN7C roads which was generating in turn problems at the Pitești motorway end. The underpass was fully completed during October 2008.
