The A1 motorway in Romania is currently under construction, with the goal of connecting Bucharest to the Banat and Crișana regions in the western part of the country and further extending to connect with the rest of Europe.

Upon its full completion, the motorway is anticipated to stretch 580.2 kilometers, traversing the country in a roughly southeast to northwest direction. Notably challenging in terms of construction, the Sibiu- Pitesti section poses the most difficulty due to the necessity of crossing the Carpathian Mountains, partly following the Olt River Valley.
