The Ada Bridge (Serbian: Мост на Ади / Most na Adi) or alternatively Sava Bridge is a cable-stayed bridge over the Sava river in Belgrade, Serbia. The bridge crosses the tip of Ada Ciganlija island, connecting the municipalities of Čukarica and New Belgrade. The bridge pylon is located on the tip of the island, which has been reinforced with large amounts of concrete and has been slightly enlarged to provide stronger foundations. Construction began in 2008, and the bridge opened on 1 January 2012.[2] Adjoining roads were completed in 2013.[3]


Ada bridge in front of other Belgrade bridges

In 1923, architect Đorđe Kovaljevski created the first urbanization plan of the area that envisaged a bridge over Ada Ciganlija.[4] The initial idea of what is today known as the Belgrade Inner City Semi-Ring Road, to which the bridge is an important part, were created at that time. This road was part of several plans under different names such as the Main Ring Road, Transverse Road, Eastern Tangent Road, each with slightly different routes. All the plans had one thing in common: the Ada Ciganlija Bridge. In early plans the bridge was placed closer to the Lake while the final project placed the bridge on the very tip of the island due to ecological concerns over the lake.[4]


Ada Bridge is the most upstream Belgrade bridge over the Sava river within the urban area. The bridge provides the only direct connection between the New Belgrade (Blokovi) and Čukarica (Banovo Brdo) municipalities.[3] The bridge pylon is located on the tip of the Ada Ciganlija island.


Bridge at night

The competition for the preliminary design of the bridge was held in 2004. Twelve companies submitted bids, with the winning design by the Slovenian company Ponting. The bridge designers were the architects Viktor Markelj and Peter Gabrijelčič.[5] The winning conceptual design was unanimously selected by the jury which was chaired by Nikola Hajdin, President of the Serbian Academy of Sciences and Arts and the architect of the New Railroad Bridge.[6] The Belgrade Association of Architects also endorsed the project, assessing it as contemporary and relevant to the future skyline of Belgrade.[7]

The bridge is a cable-stayed design with a single pylon. The foundation for the pylon is a circular diaphragm wall with 113 bored piles. The main span is constructed from 8,600 tons of bridge construction steel (grade S355J2+N), supported by 80 stay cables, and is counterbalanced by a post-tensioned, reinforced concrete back span of 200 m (660 ft). The approach towards New Belgrade is constructed as a 388m post-tensioned, reinforced concrete side span as continuous beam box girder with a similar arrangement of deck as the back span. Component parts of the deck were manufactured in China and delivered in transportable units on a sea and river-route via Rotterdam through the Rhine–Main–Danube Canal to the pre-assembly yard next to the construction site at Mala Ciganlija in Belgrade. The stay cables used to support the bridge deck have a maximum length of approximately 373 m (1,224 ft), and in total 1280 tons of high grade steel is used for the 80 cables with up to 91 strands.[8]

The bridge is designed to significantly reduce traffic passing through the city centre and the older Gazela Bridge. It is planned to be part of the future Belgrade Inner City Semi-Ring Road. It will have three road lanes and a tram (light rail) track in each direction.[citation needed]


Pylon under construction, May 2010

Construction began in 2008 and ended in 2011. The bridge was opened to public traffic on 1 January 2012 at 00:00.


The construction was commissioned by the Belgrade Land Development Public Agency and co-financed by the City of Belgrade, the European Bank for Reconstruction and Development, European Investment Bank and several private financiers.[citation needed]

The contract for a Project Manager and Engineer was awarded to Louis Berger Group. Their job was to provide support to the City of Belgrade in all aspects of project cycle management, including design review, preparation of works documentation, procurement, works supervision and contract administration.[9]

Engineering and construction of the bridge was awarded to a consortium of three companies, Porr AG from Austria, Slovenija ceste Tehnika from Slovenia and DSD Brückenbau GmbH from Germany.[10][11][12] The consortium engaged several subcontractors, including Leonhardt, Andrä und Partner from Germany, China Railway Shanhaiguan Bridge Group from China, Vorspann Technik from Germany, BBR from Switzerland, the University of Belgrade's Faculty of Mining and Geology, Eusani-Hortmanns-Zahlten Ingenieurgesellschaft from Germany, Ponting from Slovenia, BBV from Germany and the Institute Kirilo Savić from Belgrade. The North Approach Road's detailed design was by Hidroprojekt – saobraćaj from Belgrade. the South Approach Road's detailed design was by Centar za puteve Vojvodine from Novi Sad, and the Paštroviceva Street detailed design was by IM Projekt from Belgrade.[12]

In popular culture[edit]

Ada bridge was featured in the fifth episode, season nine of the Discovery Channel documentary television series Build It Bigger.[13]
