The bridge, 1,507 metres long and 29.1 metres wide, took over three years to build and cost around $260 million (211 million euro), the government said in a statement after prime minister Aleksandar Vucic attended the commissioning ceremony.
China's Ex-Im Bank financed 85% of the construction costs with the Serbian government and the city of Belgrade financing the remainder with their own funds.
The bridge was built by the China Road and Bridge Corporation.
