E70/E75 Motorway Belgrade, Bypass R251


Delegation of the European Commission to Serbia




2008 – 2011


Supervision of all works under FIDIC Red Book; assistance to Serbian roads administration regarding work contracts; review of design

  • Supervision under FIDIC Red Book

Project objectives

The supervision under the FIDIC Red Book related to two works contracts. The road works on the 6-lane motorway through Belgrade comprised primarily pavement rehabilitation over a length of some 30 km as well as lighting and traffic signalling. The works contract for the bypass (app. 30 km) included pavement rehabilitation, traffic signalling, the rehabilitation and equipment of the Strazevica tunnel (length. app. 500 m), the stabilisation of three landslides and additional intersections.

Project data

The Serbian motorways and roads network has been severely affected by war damage and has suffered from the lack of investments resulting in heavily deteriorated sections of the network. Two sections of crucial importance for both the traffic in and through Belgrade and the regional traffic on Transport Corridor 10 are the motorway E70/E75 and the bypass R251 Bubanj Botok – Vinca. Earthworks in both sections amounted to some 120,000 m³. In total 5,500 m³ of concrete were required for structures including the new tunnel lining and some 120,000 tons of asphalt.

Project content
