Belgrade Bypass

Belgrade Bypass

By construction of the Belgrade Bypass the branch of the Corridor Xb, E-75 (border with Hungry,  Horgoš- Novi Sad-Belgrade) will be connected to the Corridor X, E-70 (Border with Croatia Batrovci-Belgrade), I B Category state road No. 26 and Route 4, E-763 (Belgrade-Požega-border with Monte Negro Boljare), and again to the segment of the Corridor  X, E-75 (Belgrade - Niš – Preševo – Border with Republic of North Macedonia). Positive effects of the construction of the Belgrade Bypass will be felt when vehicles are diverted from highly frequented core urban road networks of Belgrade to the Belgrade Bypass, which will contribute to the utterly improved influence on traffic flow on the Bypass, and at the same time on traffic flow on the core network of urban roads under the most intensive traffic. 

The effects of the abovementioned improvements will reflect on:

Reduced travel time for transit traffic flows which will be diverted to the Bypass, as well as for initial and end flows using the Bypass; reduced congestion on the segment of the core network of urban roads under the most intensive traffic; reduced number of traffic accidents on the core network of urban roads under the most intensive traffic; reduced costs of vehicle exploitation; reduced toxic gases and noise in the narrow city area. 

Traffic flows using the Bypass instead of segments of the core network of urban roads under the most intensive traffic, especially transit flows, would receive “services of the 5 star hotel in place of ‘no star’ hotel”. 

Bypass route has been designed within the corridor specified by the Belgrade Master Plan as the one to be used for passage of roads through Belgrade City area. Due to such circumstance, mutual spatial and functional ratio between the motorway and the city has been very carefully studied and the section has been designed accordingly to satisfy all the criteria of an international motorway, simultaneously representing a positive factor in the development of the city. 

Belgrade Bypass comprises the following sections:

Section A: Batajnica-Dobanovci – works on the route and on Dobanovci and Batajnica interchange are completed.

Section B: Dobanovci – Bubanj potok

It consists of 6 sectors, as follows:

  • sectors B1-B3: Dobanovci – bridge on the Sava at Ostružnica: completed works
  • bridge on the Sava at Ostružnica: completed works
  • sector B4: completed works
  • sector B5: completed right highway lane from the interchange “Orlovača” to the exit from the tunnel Straževica (phase I), works on the construction of the left highway lane (phase II) and of the tunnel Straževica left tube are in progress
  • sector B6: tunnel Straževica – interchange Bubanj Potok, works on the construction of the left and the right highway lane are in progress

Section C: Bubanj potok - Pančevo (E-70) – upcoming works
During the 1980s, a special Feasibility Study was prepared for the motorway section Dobanovci-Bubanj potok. This Study analyzed all the alternatives and examined all the economic parameters, concluding that this represented a priority as well as a profitable investment in Serbia’s road network.

2005 godine je Evropska Agencija za Rekonstrukciju finansirala izradu Studije ekonomske opravdanosti izgradnje Obilaznice oko Beograda koja je kao polaznu osnovu uzela predhodnu verziju Studije.


Total length of the Bypass section from Dobanovci to Bubanj Potok is 47.4 km and it was designed with design speed of 120 km/h.

The road profile consists of:

  • driving lane ............................ 4 x 3.75 m
  • emergency lane ...................... 2 h 3.00 m
  • marginal strip .................... 2 h 2 x 0.50 m
  • median strip .............................. 4.00 m
  • shoulder ................................... 2 h 1.50 m

Total ......................................................30.00 m

Minimum applied horizontal curve radius is 1,000 m, and maximum gradient is 3.8%.


Five nods are designed on this section: two of the being at section ends and three in the middle part of the section. 
Solutions for layout and elevation of the basic alignment are specified in such a manner that the construction of other interchanges will also be possible in the future, provided that justified traffic reasons substantiate such an action.


There are 41 bridge localities with 79 structures on the section Dobanovci - Bubanj potok. 
The biggest bridge is the one over the Sava River near Ostružnica, consisting of three structures in total length of 1,965 m (steel structures over the river and approach concrete frameworks on both banks).
All other bridges are concrete, whereas five bridges are distinguished by size: “Sveta Petka“ (408 m), “Železnička reka“ (406 m), “Kijevski potok“ (571 m), “Topčiderska dolina“ (597 m) and “Bridge over the railway line”, 430 m).


Four tunnels are designed on this route and those are the following: “Lipak” (partially under the plateau of the railway station Ostružnica, length 665 m), “Železnik” (699 m) and “Beli potok” (under Avala road, 360 m) with two tunnel tubes, and the “Straževica” Tunnel (under Resnik, 745 m) with two separate tubes.

The project is being realized in two phases, with regard to the content of the cross-section. The first phase is based on construction of one carriageway of 11.5 m and its functional use for two-way traffic. However, it contains all the elements of the final solution that will enable simple upgrade to full motorway profile. Additionally, this phase includes expropriation of road area for the final solution. The second phase (now in progress) comprises the completion of all the remaining works in accordance with the final Design.
