This is the most difficult section of the whole motorway from construction works perspective, considering that it has to cross the Carpathian Mountains, partly along the Olt River Valley. The feasibility study was initially completed during late 2008 with plans to start construction works next year, however the Romanian Government has continuously delayed the start of the activity until 2012, considering several options on how the motorway construction was to be funded, while advancing several deadlines for the start/completion of works on the section. As during early 2012 the section was accepted to be funded under European Union's Cohesion Fund, the 2008 feasibility study had to be updated with several key elements required by the European Union that were previously not considered. The tender for the update was launched in April 2012 aiming to have the section finalized by 2020, as total construction costs for its 116.6 kilometers were estimated at 3.25 billion euro. Eight months later the Romanian Government reconsidered and cancelled the tender.
