The Bucharest Ring Motorway (or the Bucharest Belt Motorway, Romanian: Autostrada Centura București), termed A0, is a partially built motorway ring around the city of Bucharest, the capital of Romania. It is serving as a second, outer ring around the city, the first being the existing Bucharest Ring Road.
It is split into two major sections: the northern and southern half-rings that are each divided into multiple lots. When fully built, it will have a total length of approximately 101 kilometers and will be a motorway connection between the existing A1, A2 and A3 motorways.
As of July 2025, the southern half-ring is fully completed and operational, while on the northern half-ring traffic only one lot is fully completed together with a small portion of the adjacent one. The rest of the northern half-ring is under construction. The parts of the motorway currently in service include the section between DN1 and DN2 on the northern half-ring, while connection between A1 and A2 motorways is possible via the southern half-ring.
