Romania's Ministry of Transport has announced that it plans to build the new Bragadiru - Voluntari metro line 7 in Bucharest through a public-private partnership or a concession.

The  new 25km metro project would include 30 stops, a depot and a parking. The project cost is estimated at €1.5 billion (US$2.04 billion) and its construction could take six years.

Bucharest currently has four metro lines, and some 69 kilometers of metro tracks, with 51 stations. It is one of the most accessed systems of the Bucharest public transport network with a ridership of 172.6 million passengers in 2012.

The company is fully owned by the Romanian Government through the Ministry of Transportation.
