Why are suspended roundabouts being built on the Capital Ring Road

Four suspended roundabouts on the Capital Ring Road are currently under consideration: the Domnești roundabout is already open, the Berceni and Oltenita roundabouts are under construction, and in Cernica work has been suspended with an Italian builder unable to mobilize for construction. site for two years.

The suspended roundabout solution is applied to the Metropolitan Ring Road, as it is attached to the Ring Road, so any crossing must also identify traffic directions over the railway.

In essence, the suspended roundabouts will allow drivers to travel in either direction as well as bypass the ring railway (without crossings), while the Ring Road will remain on the ground and will no longer have conflicting intersections in its travel path.

The current ring road will be widened to four lanes between the Oltenice road and the Berchen road, making a total of about 6 kilometers of widened road.
