The Belgrade city road bypass (Serbian: Обилазница око Београда / Obilaznica oko Beograda) or Belgrade bypass, is a bypass road currently under construction around the city of Belgrade, the capital of Serbia.
The project is financed from the National Investment Plan, the European Bank for Reconstruction and Development, and the European Investment Bank. The project costs for phase 1,2 and 3 is estimated at €543 million.
The bypass was planned by the Belgrade's general urban planning, and its parts have been sporadically built for 17 years. However, the works intensified around the end of 2005. Its construction is expected to help alleviate Belgrade's traffic congestion, and remove all transit traffic from the city center, unloading the critical Gazela and Pančevo Bridges. The total length of the bypass will be 69 kilometres.
On January 21, 2012, the Minister of Infrastructure of Serbia Milutin Mrkonjić has said that the Section B of the bypass will be opened for traffic in May 2012, 6 months before scheduled completion. Mrkonjić repeated that promise on February 26, 2012.
The bypass will consist of three principal sections:
Part of Section B from Dobanovci to Orlovača was finished and opened for traffic in October 2008. All heavy trucks were banned on Gazela bridge in March 2010, effectively redirecting all truck transit over the Section B.
Section A was opened for traffic in May 2012, along with the Orlovača–Straževica part of the Section B. Batajnica interchange, the origin of section A, is still incomplete, with only one side of the viaduct in operation. Of the section B, the part between Straževica tunnel and Bubanj potok is still under construction, operating as single carriageway.
Section B, spanning the hilly terrain, will include 4 tunnels and 40 viaducts when completed, nine of them over 400 m long. In the final stage, it will also require enhancement of the existing Ostružnica bridge to accommodate the planned dual carriageway.
