The A1 motorway (Romanian: Autostrada A1) is a partially built motorway in Romania, planned to connect Bucharest with the Banat and Crișana regions in the western part of the country and the rest of Europe.
When completed it will be 580.2 kilometers long and it will span the country on the approximative south-east to north west direction.
The motorway starts in the western part of Bucharest and connects the following major cities: Pitești, Sibiu, Deva, Timișoara, Arad, reaching Hungary's M43 motorway near Nădlac.
As the motorway is built along the Trans-European Transport Networks Rhine-Danube Corridor the construction receives 85% funding from the European Union. The road is part of the proposed Via Carpatia route.
