The city’s municipal road network is centered around a series of high-capacity boulevards (3 to 4 lanes on each way), which generally radiate out from the city centre to the outskirts and are arranged in geographical axes (principally North-South, East-West and Northwest-Southeast).
The main (and most congested!) boulevards are Calea Victoriei, Stefan cel Mare, Str. Buzesti, Bulevardul Unirii, and Mihai Bravu Boulevard, which is the longest in Bucharest and forms a sort of semicircle around the northeastern part of the old sector.
The city also has two ring-roads, one inside ring (Mihai Bravu is part of it) and one outside ring, which are mainly used for cars that bypass the city as well as trucks, which aren’t allowed in the city centre.
Aside from the main roads, the city also has a number of secondary roads, which connect the main boulevards. In the historical city centre, particularly the Lipscani area, many streets are cobbled and are classified as pedestrian zones.
The traffic in Bucharest has improved after the opening of the 1.9 – km Basarab flyover, which was inaugurated in the summer of 2011, after five years of works. It connects the West of the city to the Northern area.
