The Pupin Bridge is a road bridge over the Danube River in Belgrade, Serbia. The bridge is located upstream of the city center and connects Belgrade neighbourhoods of Zemun and Borča. Opened in December 2014, it became the second bridge over the Danube in Belgrade, after the Pančevo Bridge. During the construction, its tentative name was Zemun–Borča bridge, but later it got named after Serbian scientist and inventor Mihajlo Pupin. The bridge and 21.6 km of new access roads will help to divert heavy traffic from Belgrade city centre. The bridge is designed as two independent bridge structures of three car lanes 3.5 meters wide and pedestrian-bicycle paths on both sides. The bridge construction costs of EUR 170 million were provided by the Chinese Exim Bank (85%) and the Government of Serbia and the City of Belgrade (15%). The Chinese-built bridge was also China’s first big infrastructure investment on the European continent.
