Spanish construction firm Acciona Infrastructure in a consortium with its Polish subsidiary Mostostal Warszawa won the contract.
The Oder Bridge will have the ninth longest cable stayed central span in the world and the second longest in Europe, after the Pont de Normandie in France. The bridge will span 612m over the main channel of the river with two back spans of 611m and 521m on each side of the river, giving it a total length of 1.75km.
The Oder Bridge will be part of the Wrocław bypass in eastern Poland, linking the A4, the future S5 road to Poznań and the S8 to Warsaw. At a height of 122m, the central pier will be the tallest structure of its kind in Poland. It will be located on Rędzińska Island in the middle of the river.
The bridge will also be the first in Poland to be fitted with sensors to detect damage or deterioration to components.
The £125.5M contract, awarded by the Polish Roads Authority, will take two and a half years to build.
