It appears that the Highway 25 bridge wasn’t constructed until 2006-2007.

European Union Bridge – a road bridge over the Warta River in Konin in the Wielkopolskie Voivodeship along the national road No. 25. The extradosed bridge is the second crossing of the Warta River in the city.
The bridge with access flyovers over the Warta Valley, 3,400 meters long, was built by the consortium of Hydrobudowa-6, Warszawskie Przedsiębiorstwo Robót Drogowych and Płockie Przedsiębiorstwo Robót Mostowych in 2006-2007.
The cost of building the bridge together with the new section of the national road No. 25 amounted to approx. PLN 200 million and was 75% co-financed from the European Regional Development Fund. The bridge, put into use on December 15, 2007, was given the name of the European Union by a resolution of the Konin City Council.
The nearest crossing of the Warta river upstream is Most im. Marshal Józef Piłsudski in the center of Konin along the national road No. 92, and downstream the bridge along the A2 motorway.
